FIELD TRIP

“Past Earthquakes and Active Structures of the L.A.Region”Field trip is led by James Dolan, Kate Scharer, Doug Yule andJerry TreimanFriday 24 April 8 AM--6 PM

This fieldtrip will focus on major faults of the northernLos Angeles metropolitan region, including the geologic effectsof the earthquakes that they generate. We plan to take apassenger bus to the following locations: (1) Griffith ParkObservatory. From here one can see the breadth of the LABasin, looking south, at uplift along the Newport-Inglewoodfault and looking north, at fold and thrust systems stackedup under the San Gabriel Mountains. This first stop willprovide a framework for the types of geologic structures thatpose a hazard to LA infrastructure and communities, as wellas a detailed discussion of the Puente Hills and Comptonthrusts, two major blind thrust faults that underlie muchof the metropolitan region. (2) Hollywood fault. This faultwas recently designated as an Alquist-Priolo Earthquake FaultZone by the California Geologic Survey. At this stop we willdiscuss approaches for collecting geologic data on active faultsin urban areas. (3) Historic reverse fault earthquakes in theSan Fernando Valley. This stop will discuss the seismologicand geologic effects of the 1994 Northridge and 1971 Sylmarearthquakes. (4) Time permitting, we will have a final stop

2014 National Seismic Hazard Mapping Updates: HazardChanges and Influence on Seismic RiskTheU.S. Geological Survey publishes new seismic hazardmapsevery six years. These maps display probabilistic estimatesof earthquake ground shaking across the United States atvarious recurrence intervals. The maps are applied in seismicprovisions of building codes, insurance rate structures, riskassessments, and other public policy. Effective communicationof the seismic hazard maps, associated uncertainties in hazardestimates, and their updates over time could pose a seriouschallenge. The session aims to pool together certain keystakeholders from the variety of end-users of these maps,and examine how the changes introduced through differentversions have influenced their decision-making. To begin, wewill discuss some of the key changes that were introducedduring the 2002, 2008, and 2014 cycles of National seismichazard maps and how they have influenced our understandingof earthquake hazards throughout the nation. In addition, thesession will also highlight some of the implications of changesin hazard in terms of measures such as human exposure,annualized earthquake loss/risk estimates, changes in designcriteria, and insurance pricing.

Advances in Earthquake Source InversionEarthquake source inversion and high-frequency ruptureimaging provide time-dependent information on earthquakerupture processes, but a synoptic view of the origin andimpact of the resulting uncertainties on the estimated sourceparameters has not been fully developed. Furthermore, theoptimal integration of various datasets, and the combinationof source inversion and source imaging, to derive a completeunderstanding of the kinematic rupture evolution in space andtime, still pose many open questions. In this context, reliablenear-real-time finite-fault parameter estimation are needed, aswell as high-fidelity rupture-history inversions.

This session aims at highlighting recent advances andcomparative studies in finite-fault earthquake source inversion,including the development of innovative inversion andimaging methods and the rigorous estimation of modeluncertainties. We also invite contributions that integrateobservational earthquake seismology with earthquake physicsand tectonics, with potential applications in ground motionprediction and early warning studies, to motivate newdevelopments in source characterization, to define new

metrics for source inversion validation, and to help buildmore realistic dynamic models of the earthquake ruptureprocess. In addition, we welcome contributions that highlightdevelopments towards "as-automatic-as-possible" finite-faultinversion, as such procedures will greatly facilitate thevalidation process of source inversions.

Advances in High-frequency Ground Motion andAttenuationGround motion at high frequencies (1-30 Hz) has recentlybeen a core issue in large seismic hazard assessment projects,following the Fukushima accident. While existing criticalfacilities and concrete dams are being reassessed in viewof high-frequency response and attenuation, broadbandsimulations are attempting to reach unprecedented highfrequencies. This session welcomes all contributions related tohigh frequency ground motion, with emphasis on attenuation.Topics of interest include: how physics-based and otherbroadband simulation techniques handle high-frequencyattenuation; crustal attenuation studies; anelastic attenuationand scattering effects at high frequencies; spectral analysisstudies where results (Q, stress drop) may be subject totrade-offs between kappa and source, path and site effects inthat frequency range; studies of hard-site amplification androck site characterization; adjustments of ground motionprediction equations (GMPEs) and host-to-target techniquesthat take into account high-frequency attenuation; newgeneration GMPEs explicitly accounting for kappa; resultsand experiences from PSHA projects for critical infrastructurethat account for high-frequency attenuation; and work on theestimation, components, and physical interpretation of kappaand fmax.

Applications of Tsunami Science: Working with Statesand Communities to Improve Tsunami ResilienceEffective tsunami mitigation programs benefit from aninfusion of new research and technologies into practicalmitigation and preparedness efforts at the community andregional level. Historical and paleo-tsunami information helps


determine the impact and recurrence of large tsunamis fora particular source or region and provides physical evidencefor rare events that enriches outreach efforts. Improvementsmade in source and numerical tsunami modeling providecommunities with enhanced tsunami hazard and risk productsused for evacuation and preparedness planning, and improvedresponse during a tsunami event, including development ofreal-time products for communities. Lessons learned from the2011 Tohoku-oki tsunami are now being applied in tsunamimitigation programs worldwide.

This session will focus on application of techniques andtechnologies into mitigation and education efforts and theireffect on community resilience. This includes: 1) advances intsunami engineering, vulnerability, and risk analysis products;2) tools to help with scenario-specific tsunami preparednessand real-time response; and 3) improved planning andeducational resources.

The August 24, 2014 South Napa, CA Earthquake: ScienceResults, Impacts and Lessons LearnedThe M6.0 South Napa earthquake continues to be a scientificsurprise: extensive, distributed surface rupture coupled withspatially varying, large magnitude post-seismic slip havechallenged our notions of the relationship between faultslip at depth and static and dynamic ground motions andtheir associated hazards. In addition, in part because of itsproximity to a major population center, and in part becauseof the concurrent maturation of new technology, this eventhas been studied and imaged by myriad new systems andplatforms with exceptional spatial and temporal density. Weencourage a broad range of contributions to this session thatwill highlight what we have learned from this earthquake andhow this will be applied in practice in order to mitigate thedamaging effects of future earthquakes on society. Suggestedtopics include the application of new technologies to post-earthquake response, application of remote sensing techniquesto detect ground failure, results from, and integration of,LiDAR and fieldmapping, geodesy, performance of earthquakeearly warning systems, geology, seismology, ground motions,site response, performance of buildings and infrastructure, andpost-earthquake coordination activities.

Capturing Site Effects in Strong Ground MotionSite effects on strong ground motions include the effectsof surface and sub-surface topography, stratigraphicdiscontinuities, and soil layering. These three-dimensional(3D) effects are known to affect the amplitude, frequencyand duration of ground motion through mechanisms ofground response (including impedance and resonance effects),basin effects (e.g., preferential focusing, and/or trappingof seismic energy), and topographic effects (resonance of atopographic feature, energy reverberations in confined space).

Site effects have been documented extensively in the literatureand have been studied through experiments, analytical,numerical and empirical methods. In practice, site effects areaccounted through semi-empirical GMPEs, which capturethe average net site effect (primarily from soil amplification)conditional on the site parameter that is used (typicallyVs30 and basin depth), but ignore higher-dimensional (3D)site effects such as topographic amplification. The purposeof this session is to facilitate the dissemination of recentadvances in the understanding, monitoring, simulation andparameterization of 3D site effects in ground motion. Specifictopics include recent advances in the mapping and inferenceof site parameters (Vs30, basin depth and beyond), semi-empirical models for 3D site effects, simulation-based modelsand experimental studies on 3D site-specific response effects,and procedures to account for 3D site effects in seismic codeprovisions.

Central Coastal California TectonicsEarth science data collected in central coastal California sincethe 2003 San Simeon and 2004 Parkfield earthquakes havesignificantly added to the understanding of the tectonics andseismic hazard of the region. In particular, the applicationof new technologies (e.g., differential GPS, GIS, multibeambathymetry, airborne and marine magnetics, low energy2D/3D seismic reflection, and autonomous seismographnodes) through cooperative public-private sector research hasenabled high-resolution geophysical imaging of the centralCalifornia coastal region and has helped reduce the uncertaintyfor a number of seismic hazard significant parameters

This session will feature results from the PG&E-sponsored Central Coastal California Seismic ImagingProject – a multidisciplinary offshore/onshore study ofcrustal structure, marine paleoseismology, and seismic hazardnear the Irish Hills. In addition, this session will highlightcooperative geologic and geophysical research efforts includingthe PG&E /USGS Central California Cooperative Researchand Development Agreement (CRADA) and the CaliforniaSeafloor Mapping Program. We welcome independentresearch submissions that focus on the tectonics and seismichazards of the central California coast.

Characterizing Ground Motions and Active Faults in UrbanAreasShallow materials can result in significant ground motionamplification or ground failure during earthquakes, anddetermining whether active faults lie beneath cities is a keyparameter for seismic hazard analyses. However, characterizingthe effects of shallow deposits and active faults beneathurban areas can be hampered by the built environment


and high levels of ambient noise. This session solicitscontributions describing methodologies for characterizingurban earthquake hazards. We encourage contributions thatinclude the estimation of ground motion variations fromnatural and anthropogenic soils, basin-scale site response, andidentification and characterization of active faults. Topics ofparticular interest are descriptions of methodologies suitablefor rapid assessments of ground conditions and subsurfaceimaging throughout large urban areas, and studies using densearrays of measurements.

Characterizing the Potential Impacts of Surface FaultRupture on Transportation SystemsThe linear nature of terrestrial transportation systems suchas highways, railroads and product conveyance systems issuch that crossings of active faults cannot always be avoided.Consequently, critical elements of transportation systems suchas bridges, tunnels and other structures must sometimes bedesigned for surface fault rupture hazards. Reliable estimatesof the magnitude, sense and distribution of surface faultrupture displacement is critical for a robust design. Methodsfor performing deterministic and probabilistic analysis of faultrupture displacement are evolving, aided by an ever-increasingempirical dataset. Empirical observations on the performanceof structures subject to fault rupture offset provide importantinsight into the behavior of such systems. This session willincorporate presentations on recent advancements in thisfield, including research on surface fault rupture hazardcharacterization and in the application of research in the designof transportation projects.

Earthquake Hazards and Risk: Drivers and Consumers ofEarthquake ResearchEarly earthquake hazard models date back to the 1960’swhereas the first earthquake risk models were proposed circathe 1990’s. Both the motivation and methodologies for thesemodels have evolved substantially since. In particular, recentadvances in ground motion prediction equations, probabilisticsource modeling, inventory compilation, computationalengines and vulnerability studies have led to improved hazardand risk modeling advances. Yet, significant gaps and largeuncertainties remain. In this session, we invite hazard and riskprofessionals—particularly those in the user community—todescribe their challenges and their needs in this field forfocused research and future products. Our hope is to motivatediscussion between hazard and risk disciplines including thoseamong academia, and practicing professionals, modelers, andthe related user communities. Topics including how to addressthe complexity of earthquake sequences, scenario developmentand use, and loss and risk modeling are encouraged.

Earthquake Processes and Multiscale Modeling andCharacterization of Fragmentation and Damage Patternsin Fault ZonesThe brittle portion of the crust contains structural featuressuch as faults, jogs, joints, bends and cataclastic zones thatspan a wide range of length scales. These features havea profound effect on earthquake nucleation, propagationand arrest mechanisms. They also contribute to prestressheterogeneity and complexity of ground motion patterns.

The feedback between seismic/aseismic slip and thesegeometric features leads to (1) different slip modes thatranges from extremely localized to widely distributed, (2)activation and de-activation of many of these geometricfeatures during the seismic cycle, and (3) different spatio-temporal distributions of aftershocks and nucleation sites.

This session solicits contributions in the broad area ofmultiscale modeling and characterization of fragmentationand damage generation in fault zones. Possible topics include,but not limited to: (i) constitutive modeling of rate dependentdamage accumulation and healing in rocks, (ii) fault zonetopology evolution through strain and strain rate dependentgrain size evolution, (iii) strain localization in fault gougeand its influence on off-fault damage generation, (iv) fieldinvestigations of spatiotemporal distribution near faultsurfaces, (v) computational earthquake models that accountexplicitly for inelastic processes on and off the faults.

Engineering and Public Safety Concerns Raised bySeismic Hazard Assessment MethodsObserved hazards and structural performances in recentearthquakes such as the 2014 Napa earthquake (NorthernCalifornia), 2009 L’Aquila and 2012 Emilia earthquakes(Italy), 2011 Tohoku earthquake (Japan), etc. raised concernsabout public safety and estimated hazard and risk for futureevents. The session is an open discussion on various aspectson seismic hazard assessment (SHA) approaches as it directlyrelates to engineering and public safety applications. So farthere have been basically two differing assessment approaches(viz., deterministic and probabilistic) used by scientists.Recently, the enhanced deterministic, neo-deterministic SHAhas been proposed. A goal of this session is to provide balancedinformation to the public by its proponents.

The discussion will involve the concept and practicalityof the approaches with respect to data, theory, assumptions,analysis, costs/benefits, results, experience, purpose/objective,track record, and history. Important practical questions forthe session include: Do we have the confidence that we cando better with one or the other methodology? Do we havereasonable and adequate data available at this time, as requiredby each of the respective approaches, especially for engineeringand public safety applications? Do we have any method forassessing adequacy of SHA performances? Do we have any


objective assessment of the costs and benefits related to over-and under-estimated SHA’s? What should be done for thefuture when actual events exceeded hazard estimates by aparticular approach as noted in several recent instances? Is itnecessary or not, to relate design or useful life of structures toseismic hazard level and how realistic are those life determined?Are we prepared for the largest potential events?

Expanding our Understanding of ExplosionPhenomenology Through Analysis and Modeling ofSeismic Observations and Complementary Data TypesA thorough understanding of explosion-related phenomenarequires a synthesis of many observables, modeling techniquesand analysis methods. Determination of details such asexplosive yield, source radiation pattern, depth-of-burial orheight-of-burst, etc., is often not possible with seismicdata alone. Physical constraints can be applied from thefields of infrasound, materials testing, hydro-acoustics, remotesensing, geology, and electromagnetic signals, among others.This session will highlight examples and techniques ofmulti-disciplinary explosion-source studies. We also invitesubmissions about advancements in any individual field thatextends our understanding of underground and subaerialexplosions and their effects.

From Newspapers to Numerical Analyses: Documentingand Understanding Earthquakes in Central and EasternNorth AmericaRelative to western North America finding young faults incentral and eastern North America (CENA) is a rare, butmuch appreciated, achievement. Because it is difficult tofind faults and get direct paleoseismic data from a trenchacross faults in CENA, a wide variety of research mustbe employed to reveal the earthquake history. Further, therelative paucity of recent and historic earthquakes in muchof CENA stymies an appreciation of the temporal and spatialpattern and origins of seismicity. We seek contributions fromthe spectrum of approaches that can provide insight intoearthquake occurrence in low-strain settings. For example,approaches may include historical accounts, sand blow andspeleothem studies, geomorphic analyses, crustal imaging, and

geodetic modeling and seek to document past earthquakeactivity and/or improve our understanding of why, where, andwhen earthquakes occur in CENA.

How Reliable Are Reconstructions and Models ofSurface-Rupturing Earthquakes?Historic surface-rupturing earthquakes have demonstrated apotential for complex, discontinuous rupture traces. Withthis in mind, how well do reconstructions and models ofpast ruptures from paleoseismology, geomorphologic slip-ratestudies, or finite fault models and forecasts of future surface-rupturing earthquakes [e.g. UCERF3 (CA),WGUEP (UT), J-SHIS (Japan)] realistically describe the complexity of surfaceruptures? Are earthquake magnitudes and rupture lengthsfrom empirically-based models consistent with individualfield-based observations (e.g. timing, displacement) of pastevents? This session will highlight advancements in earthquakescience that improve our understanding of fault segmentation,rupture dynamics, distributed deformation, along-strike anddown-dip fault-slip gradients, and related seismic hazardtopics. We welcome abstracts from a wide spectrum ofscientists, including paleoseismologic studies of Quaternary-active structures, detailed studies of modern ruptures, anddynamic or simulator models of rupture scenarios. We invitediscussion of new, innovative approaches that characterizeactive structures and earthquakes using field-based techniques,computer modeling, and remote sensing. The goal of thissession will be to consider ways to improve the documentationof past earthquakes and to advance our estimates of earthquakeprobabilities.

Induced SeismicityInduced seismicity particularly due to oil and gas activitieshas garnered worldwide attention. Several countries in NorthAmerica and Europe have now reported likely cases of inducedseismicity that were felt by the nearby population. Recentdamaging earthquakes of M >= 4 in Oklahoma, Colorado,Ohio, Texas, and Arkansas have renewed considerableattention in induced seismicity in the U.S. Given theseoccurrences of damaging earthquakes and an increase inseismicity rate in the U.S. in the past 12 years, it is of criticalimportance that induced earthquakes are better monitoredand understood such that their hazards may be mitigated.Topics of interest to address these issues include: (1) what arethe mechanisms of induced earthquakes; (2) what methodscan be used to distinguish natural and induced earthquakes;(3) how can the hydrologic regime be modeled to assess theeffects of injection and pore pressure increases; (4) what arethe seismic source parameters of induced earthquakes; (5)what are the geologic characteristics of injection sites thathave undergone induced earthquakes; (6) can fluid-injection


induced earthquakes be controlled; and (7) how to estimatethe hazard associated with already developed and new fluidinjection fields. We invite papers on all forms of inducedseismicity but particularly those associated with waste water-injection, hydraulic fracturing, geothermal production, andcarbon sequestration. Papers from industry are particularlywelcome to better inform the research community on the stateof knowledge and practices within the community.

Linking Ground Motion and Earthquake Source Variability(SSA/ESC Joint Session)Over the past decades, it has been increasingly recognized thatthe adequate quantification and understanding of earthquakeground motion variability plays a key role for reliable seismichazard assessment, in particular for critical structures andlong return periods. New earthquake and wave propagationsimulation codes are nowadays sophisticated enough to providerealistic simulation of the earthquake rupture and associatedlow frequency ground-motion for a given set of inputparameters. We now need to provide probability distributionsof simulation input parameters and to take into account thepotential correlations between these parameters. One of thekey challenge of seismology is then to be able then to calibrateand analyze the physical factors that control the earthquakesand the ground-motion variability. For example, it has beennoticed that the variability of classically determined stressdrop estimates is significantly larger than implied from theanalysis of the between-event variability of ground motionprediction equations (GMPEs). This observation may haveprofound implications, since stress drop is an importantinput parameter for ground motion prediction, and leadsto the questions whether the variability of seismologicallydetermined earthquake source parameters is overestimatedand, in more general terms, how strongly the physics of thesource reflect in ground motion variability. We encouragesubmissions dealing with the link between earthquake sourcephysics and ground motion variability, such as studies ofGMPE between-event variability and their relation to sourceparameter variability, analysis of source parameters probabilitydistributions, dynamic rupture effects on ground motions, andthe importance of this link for hazard and risk assessment.

Microseismics in Academia, Government and IndustryGovernment and academic scientists have pursued the studyof microseismicity for many decades, primarily in the contextof monitoring and imaging fault zones and volcanoes. Industryinvolvement inmicroseismic studies has a similarly long historyin mining and geothermal settings. In the last decade, therehas been an explosion in interest in microseismics related tothe exploitation of unconventional gas and oil reservoirs. We

invite contributions to this session from all of these areasof microseismic interest. The goal is the cross-fertilization ofideas and techniques that can potentially advance the boththe science and the industrial application of microseismictechnology.

Numerical Modeling of Earthquake Ground Motion,Rupture Dynamics and Seismic Wave PropagationAdvances in numerical modeling methodology in seismologyare not only driven by emerging requirements in observationalseismology (e.g., the advent of very dense seismic arrays;demand for near-real-time simulations; the multi-scale, multi-physics modeling of seismic phenomena; etc.), but also bydevelopments in the mathematical sciences, and through theadaptation of methods originating in other scientific fields.Moreover, future methods for very large scale simulations willbe increasingly influenced by (and may in turn influence) theevolution of computer architectures and programmingmodels.

This session is a forum for presenting advances innumerical methodology, whether the principal context isobservational, mathematical/numerical, or computational.

We invite contributions focused on development,verification and validation of numerical-modeling methods,and methodologically important applications especiallyto earthquake ground motion and rupture dynamics.Contributions on the analysis of methods, fast algorithms,high-performance implementations, large-scale simulations,non-linear behavior, multi-scale problems, and confrontationof methods with data are especially encouraged.

Objective Testing of PSHA & Earthquake Forecast ModelsWhile there has been considerable debate in recentscientific literature as to the validity and usefulness ofProbabilistic Seismic Hazard Assessment (PSHA) results,their application is almost ubiquitous as a fundamentalinput to international building codes and major civil andinfrastructure developments. Recent destructive earthquakesaround the world have stimulated discussions about testabilityof seismic hazard assessments. A new wealth of data providesan opportunity for researchers and practitioners to ensure thatwe use state-of-the-art methods and appropriate input modelsinformed by testing and based on thorough and objectivedecision-making. Owing to the long time periods involvedin hazard forecasts, PSHAs will not yield a fully testablemodel in our lifetime. Furthermore, as modelling techniquesbecome more sophisticated, how can we determine whether"improvements" are truly "improvements" in skill and notjust additional complexities? New developments in hazardassessment are striving to build partial testability into themodels. In the realm of PSHA, as with any science, testing


is not only about model validation, but is a tool to learnabout strengths and weaknesses of a model. Furthermore,modern evaluation techniques can support future modelimprovements. Initiatives such as the Collaboratory for theStudy of Earthquake Predictability (CSEP) aim to developstandardized methods and models to forecast the occurrenceand hazard resulting from future earthquakes. However,do these methods provide useful and practical input intohelping understand the forecast skill of PSHAs? We invitepresentations on any of the above topics, including: short-termearthquake forecasts, earthquake forecast model testing,hazard model testing, ground-motion prediction testing(GMPE & Simulation) and testing metric development.We also solicit submissions that aim to test the usefulnessof current assumptions in all elements of PSHA, including:seismic sources (fault and areal), earthquake recurrence,maximum magnitude, ground motions, logic trees, and finalhazard outputs.

Observing Infrasonic Sources from Ground to SpaceSeismo-acoustic sources, such as (but not limited to), volcaniceruptions, earthquakes, meteor air blasts, lightning, windfarms, and chemical explosions, are being studied using high-density ground-based sensor networks. Such sources canalso be studied at higher altitudes using direct (pressuresensors on balloons or unmanned aerial vehicles) and indirect(monitoring electromagnetic fluctuations in the ionosphere orairglow emissions) measurements of the infrasonic (acoustic)field, enabling new insights of source and propagationphenomenology. This session highlights research on thedevelopment and utilization of new and existing ground, high-altitude, and space instrumentation for infrasound sensing,the description and analysis of new seismo-acoustic datasets,and the interpretation of modeling results. New theoreticaland numerical developments such as seismo-acoustic waveformmodeling are also of interest for this session.

Recent Advances in Understanding the Onshore andOffshore Southern California Fault SystemDespite being one of the best-studied fault systems in theworld,important characteristics of many active faults in southernCalifornia remain poorly understood. These include basiccharacteristics such as fault structure, slip rate, and slip historyof offshore structures and poorly exposed faults in the LosAngeles Basin and Mojave Desert. A clearer understanding offault behavior such as variations in slip rate through time, straindistribution across parallel faults in both space and time, andconnectivity between fault zones is also needed. This sessionseeks contributions that present new data and interpretations

that affect seismic hazard estimates of onshore and offshorefaults in southernCalifornia, including fault structure, slip rate,paleoseismology, and Neogene tectonic evolution.

Rethinking PSHAThe core methods behind probabilistic seismic hazard analysis(PSHA) were first formalized by Cornell in 1968. Since thattime, the fundamental components have largely remainedunchanged inmost applications: 1) a source model, oftenmadeup of zones of expected activity, or an active fault modelcoupled with a smoothed seismicity model based on catalogdata, and; 2) empirically based ground motion predictionequations that are based on several basic parameters, such asmoment magnitude and distance. The development of theindividual components has become increasingly complex inrecent years, however the basic structure has largely remainedunchanged. In this session we invite presentations that exploresome of the key assumptions currently used in PSHA andtheir implications for hazard, or alternative PSHA methodsthat might provide different insight into the hazard. Someexamples might be the improved quantification of uncertaintyin the source modelling, and moving beyond the typicalPoisson-based formulations. The development of PSH modelsis challenged by the independence of fault and catalog datasets.Can hybrid models be used to improve the forecasting skillof PSHA? How can we best incorporate GMPEs into PSHAwhen the models are becoming increasingly complex, and allparameters need to be specified in advance? Are there viablemodeling alternatives for PSHA (e.g., an integrated sourcemodel) that can improve current best-practice?

Seismic Imaging and Monitoring of Near-surface, andCrustal and Global Scales: Recent Advances and FutureDirectionsThis session will highlight leading-edge theoretical andpractical developments in seismic imaging and monitoringapplied on different scales (e.g., the meter-scale in near-surfaceseismology up to the kilometer-scale in crustal seismology)using both active and passive seismic data. This session includespresentations on various techniques inferring the structureof the Earth as well as velocity and attenuation modelsderived at local, regional, and global scales, for example,ambient noise tomography and coda-wave interferometry. Weinvite both methodological studies, which are demonstratingthe applicability of new methods, as well as studies aimedat developing new instrumentation to contribute to thissession. We welcome innovations and advances in 3Dtraveltime tomography, waveform tomography, surface waveinversion, joint inversion of multiple geophysical observationsas well as multi-repeated observations of geophysical datato detect temporal variations of large-scale environmentsas well as smaller structures such as volcanoes, fault zones


and landslides. We also invite contributions highlighting thephysical understanding of the related wave-field compositionand phenomena at different scales, its variability over space andtime and its statistical treatment. Discussions on the pitfallsand limitations of suchmethods and potential remedies are alsowelcomed.

Slow Earthquakes: Diversity in Fault Motion and TheirImplications in Earthquake DynamicsEarthquake faults show a variety of motion – from slow slipand associated tremor to supershear rupture. Slow earthquakesemerge as a major player in releasing and redistributingstress over much of the seismic cycles. They are observedglobally over multiple spatial and temporal scales. A unifyingtheory connecting this diversity and its implications onthe fault dynamics, however, remains elusive. Moreover, thefactors (fault properties, rheology, frictional and materialheterogeneity etc.) controlling varied fault slip behaviors andtheir interplay are poorly understood. We invite abstracts thathighlight different aspects of this broad spectrum of fault slipincluding, but not limited to, slow earthquakes and associatedphenomena. We are interested in slow earthquakes in all formsand sizes – from episodic tremor and slip in the subductionzones to seismic swarms operating in smaller scales. Studiesencompassing multiple styles of fault slip (slow and fast) andtheir interactions in space and time are encouraged. We solicitnew observations and analyses from all tectonic settings usingseismology, geodesy, numerical simulations, laboratory andfield experiments.

Status and Future of Earthquake Early WarningEarthquake early warning (EEW) systems have been built inselect parts of the world, and are currently being developedin several more regions including the west coast of theUnited States. While all of these systems aim to use dataobtained near to the earthquake source to warn populationcenters of imminent shaking, there is great diversity in themethodologies and data types used. We invite contributionsfrom all areas related to EEW, such as performance reviews

of early warning systems; incorporation of new datasets suchas geodetic data, gravity observations, and data from low-costinstruments; proposed new methodologies; and related real-time earthquake response issues such as tsunami early warning,damage assessment, and public communication.

Structural Health Monitoring and Earthquake DamageDetection in StructuresStrong and even moderate nearby earthquakes can causesignificant damage to structures such as buildings, bridges,dams, power plants and pipelines, which may result in lossof life and injuries as well as direct and indirect monetarylosses. Assessment of the structural health and integrity duringor soon after the earthquake, before physical inspection ispossible, may assist making timely decisions on evacuation.Timely evacuation of a weakened structure would help avoidloss of life and injuries caused by a potential collapse of aweakened structure from shaking from aftershocks. Timelydecision not to evacuate a healthy structure would avoidneedless evacuation and the costly consequences of loss offunction. Many methods have been developed over the years,such as, e.g., modal, wave, performance based and statisticalpattern recognition methods. Such methods are generallyapplicable to other disasters and to longer term conditionmonitoring. This session aims to present new developmentsand findings on all aspects of the problem, frombasic studies onthe mechanics of damage and nonlinear response of structuresto sensing technologies, methodologies and decision systems,relevant for a variety of structures and infrastructure systems.

Using Dense Seismic Array to Image the Subsurface andMonitor Earthquake ActivityDense seismic arrays that record continuously have thepotential to dramatically increase the resolution of subsurfaceimaging, and they can also be used tomonitor micro-seismicity.However, the sensors that are used in these arrays usuallylack the low-frequency response of conventional earthquakemonitoring networks, and are often deployed at the surface innoisy environments. This presents challenges for extracting thesignal from the noise. We invite scientists who have used thesetypes of data or have developed algorithms to work with thesearrays to present their work in this session.

The Where, When and Why of UncharacteristicEarthquakesUnexpectedly large and/or complex historic earthquakes, suchas the 1920 Haiyuan, 1960 Chile, 1988 Spitak, 1992 Landers,2011 Tohoku, 2012 Indian Ocean quakes, among others, begthe questions: where might the next uncharacteristic eventoccur, and have geoscientists underestimated the maximum


size and rates of these type of events? These uncharacteristicearthquakes all ruptured through hypothesized segmentboundaries that appear to impede rupture during typicalearthquakes on these fault systems. Southern Californiacontains a number of world-class examples of complex faultsystems – the southern San Andreas fault system, the EasternCalifornia Shear Zone, and the Transverse Ranges oblique-thrust system – that may spawn the next surprisingly largeearthquake. With this meeting surrounded by these examples,we seek contributions that provide global insight into the

record of and processes controlling regular versus atypicallylarge events on fault systems. We welcome abstracts utilizingthe geologic record, geophysical data, crustal deformationmodels and dynamic rupture models to shed insight into thebehavior of these potentially devastating large earthquakes.
