Earthquake Location Data for the southern Great Basin of Nevada and California: 1984 through 1986

Abstract

This report presents data in map and table form for earthquake parameters such as hypocentral coordinates and magnitudes for earthquakes located by the southern Great Basin Seismic network for the time period January 1, 1984, through December 31, 1986. These maps show concentrations of earthquakes in regions previously noted to be seismically active, including the Pahranagat Shear Zone, Pahroc Mountains, southern Nevada Test Site, Timber Mountain, Black Mountain, Gold Mountain, Montezuma Range, and Grapevine Mountains. A concentration of earthquake activity in the Reveille Range was observed in 1986, in a previously inactive area. The northern Nevada Test Site had fewer earthquakes than a comparable area of the southern Nevada Test Site, indicating that the low-yield nuclear testing program is not currently triggering significant numbers of aftershocks. Eight microearthquakes occurred at Yucca Mountain during the 1984-1986 monitoring period. Depths of focus for well-located earthquakes continue to indicate a bimodal distribution, with peaks at 1-2 and 8-9 km below sea-level and a local minimum at 4-5 km. Focal mechanisms range from strike slip to normal slip. No dependence of slip mode on depth or magnitude is evident.

Introduction

The southern Great Basin (SGB) seismograph network is operated by the U. S. Geological Survey to investigate seismicity and tectonics of the Yucca Mountain site and the surrounding region (radius « 160 km) under an agreement with the U. S. Department of Energy (Nevada- Nuclear Waste Storage Investigations Project). The network presently consists of 54 seismograph stations, 43 in Nevada and 11 in California, associated electronics, telemetry, and computer facilities in Golden, Colorado. Most of the seismograph stations are vertical-component, high-gain, short- period instruments. Eight stations also have horizontal-component instruments.

This data report summarizes the earthquake locations computed for the time period January 1, 1984 through December 31, 1986. Earthquake locations are derived using the computer program HYPO71 which incorporates the same velocity model as in previous seismicity reports (Rogers and others, 1983; Rogers and others, 1987). Earthquake local magnitudes are computed by the formulas reported in Rogers and others (1987). The velocity model and certain magnitude-determination parameters are summarized in Appendix C.

In 1984, 646 local earthquakes were located (Figure 1 and Appendix A; by "local" we mean within the map boundaries shown in Figure 1). In 1985, 1070 local earthquakes were located (Figure 2 and Appendix A). In 1986, 1111 local earthquakes were located (Figure 3 and Appendix A). A few gaps in the seismicity record for the second half of 1986 - corresponding to computer down-time (« 5%) - will be filled in in a future report, as develocorder films, which serve as a continuous backup record, are scaled. Magnitudes range from 0.0 to 3.0 (Appendix A). Figure 4 shows the seismicity for the period August, 1978, through December, 1986, i. e., since the inception of the SGB seismic network. Some of the seismically active and quiescent regions discussed below are identified in Figure 1. During that time period, a few changes were made to seismographic station locations. In 1983 station NMN was destroyed by vandals, and on November 2, 1984, station TCN (Thirsty Canyon) was installed to replace NMN. Single-component (north-south) horizontal seismometers were installed at stations PRN, GMR, JON, EPN, GVN, and PGE in 1984. Two-component horizontal seismometers were installed at YMT4 and LSM. Station parameters, including coordinates, elevations, and gains, are listed in Appendix B. The electronics of the horizontal-component seismic stations are discussed in appendix D, along with some calibration

Discussion

This data report is being distributed without detailed discussion in order to disseminate in­ formation rapidly. Discussions of seismicity patterns, focal mechanisms, and tectonic implications from data collected from 1978 through 1983 are available in Rogers and others (1987). The data of this report do not substantially modify earlier conclusions.

A few summary observations about earthquake distributions follow.(1). The seismicity at the Nevada Test Site (NTS) appears qualitatively different from that at other subregions of the southern Great Basin having comparable rates of seismicity. All other active areas show seismicity sequences having 50 or more earthquakes in a small area and brief time span, whereas NTS seismicity does not contain such clusters. Figures 5 and 6 show the cumulative numbers of earthquakes located from December 1978 through June 1986 in the southern and northern NTS, respectively. Also note that, at present, the southern NTS is about twice as active as the northern NTS, which contains the three testing zones, Pahute Mesa, Rainier Mesa, and Yucca Flat, indicating that nuclear-testing-induced activity in the northern NTS is perhaps less significant than it has been in the past. Figure 7, showing the seismicity rates for the Pahroc and Pahranagat regions, indicates two concentrated mainshock-aftershock sequences. Figure 8, showing the seismicity rates for Sarcobatus Flat, reveals multiple bursts of activity, as does figure 9, showing seismicity rates for the Grapevine Mountains and Gold Mountain. The absence of distinct clustering of epicenters in the seismically active southern NTS was noted in an earlier report (Rogers and others, 1983). This difference could be an artifact of the limited monitoring period, related to explosion-induced seismicity properties, or a result of deep-seated tectonic differences at the NTS compared to the surrounding region. At present it is not possible to choose between these various possibilities.(2). The bimodal distribution of depth of focus for earthquakes of the southern Great Basin continues to be observed in the 1984-1986 data. Figure 10 shows that well-located earthquakes (HYPO71 "A" and "B" quality solutions) have a skewed, but bimodal distribution, with peaks at 1-2 km and 7-8 km below sea level. The large number of very shallow focus earthquakes is in large part due to unmodeled high-velocity shallow rock at the Reveille and Belted Ranges, where approximately 210 earthquakes were located from February to December, 1986. The routine use of a regional velocity model that underestimates P- and S-wave velocities in crystalline surficial rock tends to decrease depth-of-focus estimates, suggesting that regional variations in SGB rock may require corresponding variations in the velocity model.

Figure 11 shows the average HYPO71 standard error estimate in each depth interval for the data of figure 10. Figure 12 shows the distribution of depth-of-focus for all HYPO71 "A", "B", and "C" quality earthquakes. Proportionately more deeper-focus earthquakes (i.e., z > 8 km) appear in this data set than in the one shown in figure 10. The dependence of estimated depth of focus on the velocity model used to perform the earthquake location, in networks having relatively sparse station distribution, such as the southern Great Basin network, is a problem when near- surface rock velocities exhibit significant lateral variation. Future plans for the network include deployment of temporary networks of densely-spaced seismographic stations to improve earthquake location estimates and velocity structure information in seismically active regions. In particular, such networks may provide data about the possible existence of zones of detachment within the seismogenic crust.(3). Twenty-seven focal mechanisms are available for the 1984-1986 seismicity (Figure 13). The compressional-wave polarity data and (SV/P) Z wavelet amplitude data used to compute these mechanisms are presented in Appendix E. An examination of Table El, summarizing the focal mechanism data, shows no clear dependence of the orientations of slip vectors (rake angles] on either magnitude or depth of focus. The 1984-1986 data include about 10 normal-slip mechanisms,

Page 8: USGS-OFR-87-596 USGS-OFR-87-596 UNITED STATES ...This report presents data in map and table form for earthquake parameters such as hypocentral coordinates and magnitudes for earthquakes

10 strike-slip mechanisms, and 3 oblique-slip mechanisms. The remaining 4 mechanisms cannot be simply classified, because the two nodal planes for each of those mechanisms imply different modes of slip. Appendix E figure captions identify the principal mode(s) of slip for each of the focal mechanisms.

Seismicity at Yucca Mountain and Vicinity

In the period January, 1985 through December, 1986, eight earthquakes were detected at Yucca Mountain and immediately to the west in Crater Flat (Figure 14). The maximum magnitude was ML 0.9. There were no Yucca Mountain earthquakes detected in 1984. Table 1 summarizes the earthquake location parameters. A report on Yucca Mountain seismicity, containing focal mechanisms and a joint hypocenter-velocity inversion, is in preparation.

Table 1. Summary of preliminary location parameters for earthquakes located at or near Yucca Mountain for the monitoring period 1984 through 1986. The "distance to site" represents the epicentral distance to the point 36°51/N., 116°27.5/ W., near the center of a potential nuclear waste repository. Depth is relative to sea-level (0.0 km). Sdx, sdy, and sdz are HYPO71 standard errors in estimates of hypocentral longitude, latitude, and depth of focus, respectively.

Conclusions

1. Zones of tightly clustered seismicity persist for several years in many parts of the southern Great Basin (e.g., Pahranagat Shear Zone, Pahroc Mountains, Gold Mountain, and Grapevine Mountains).

2. Relative quiescent zones also persist for several years in many parts of the southern Great Basin (e.g., Yucca Mountain, Crater Flat, portions of the Desert Game Ranges, portions of the Death Valley-Furnace Creek fault system).

3. E we assume that enough time has elapsed to get reasonable samples of seismicity at the Nevada Test Site relative to other regions in the southern Great Basin, then NTS seismicity exhibits a different temporal behavior due to its diffuseness or lack of bursts of localized earthquake activity. Localized clustering behavior is a characteristic feature of many other active areas in the southern Great Basin.

Appendix A

Earthquake locations for the years 1984, 1985 and 1986 and maps of quadrangle names to which locations are keyed

The local hypocenter summary column headings are for the most part self-explanatory. Hor­ izontal error equals \/sdx2 + sdy2 , where sdx and sdy refer to the HYPO71 standard errors in longitude and latitude, respectively. Vertical error is the HYPO71 standard error in depth (sdz). "AZI GAP" is the azimuthal gap, i.e., the largest angle subtended by any two station-epicenter line segments. "QUAL" represents the two HYPO71 quality estimates as defined by Lee and Lahr (1975). M&£,j is the southern Great Basin local magnitude estimate, discussed by Rogers and others (1987). Mj is the duration magnitude estimate, also discussed by Rogers and others (1987). The depths may be followed by one or two asterisks. One asterisk implies that too few phase readings were available to provide an estimate of sdz or that the depth-of-focus error estimate was very large. Two asterisks imply that the depth was fixed at 7.0 km below sea-level, a default value used when only three phase readings are available to locate the earthquake. Finally, UCT is Universal Coordinated Time, more frequently abbreviated UTC.

Hypoccntcr Parameters Used for Earthquake Location Procedure

Routine earthquake location from phase data obtained from the southern Great Basin network is done

using the computer program HYP071 (Lee and Lahr, 1975). Their program has been modified to compute

theoretical travel times of seismic rays to actual seismograph station locations, rather than to some mean

reference ground level, as in the original computer program. This modification was necessary because SGB

station elevations vary from 300 meters above sea level (station MCA) to 2620 meters above sea level (station

SVP). Since most station elevations are greater than 1000 meters, we allow earthquake depth of focus to rise

to -1.2 km, where negative depths (actually elevations) represent foci above sea level. Test variables 14 and

15 in HYPO71 have been assigned values to invoke the variable surface layer thickness option (see Table C2 below).

A second modification to the HYPO71 program computes local earthquake magnitudes according to the

methods discussed in Rogers and others (1987) in the section "magnitude estimation details." Test variables

16 and 17 in HYPO71 are assigned values to determine A/ca , the coda amplitude magnitude developed by

Carl Johnson (1979). Three event magnitudes, ML, M&, and Afca may be obtained for each digitally-recorded

earthquake. The magnitude in the column with heading "Md" in appendix A, this report, is an average of

duration magnitude, A/«f and coda amplitude magnitude, A/ca , if both estimates are available for a given

earthquake. For develocorder-film-read earthquakes, only total coda duration is routinely read to estimate

magnitudes. When a single magnitude is needed for an earthquake, for example, when plotting epicenters

according to earthquake size, we average the three magnitudes by the formula

M = 0.5A/L + 0.25A/d + 0.25A/eo .

The P- and S-wave velocity model used to locate earthquakes is shown in table Cl below.

Horizontal component seismometer electronics and calibrations

In 1984 horizontal (north-south component) seismometers were installed at stations GMN, PGE, JON, GMR, and PRN. North-south and east-west component seismometers were also in­ stalled at YMT4 and LSM. The names of these stations are GMNH, PGEH, JONH, GMRH, PRNH, YM4N, YM4E, LSMN, and LSME, respectively. Seismometer, amplifier, and telemetry electron­ ics for these stations are similar to the vertical-component seismometer electronics discussed in Rogers and others (1987, their Appendix A). A notable difference is that almost all horizontal instruments are Mark L4C seismometers, and their output is input into Teledyne-Geotech 4250 amplifier/ VCOs. The three-component station at Little Skull Mountain (LSM), however, employs S13 seismometers. A comparison of the amplification of the L4C horizontal seismometer system with Teledyne Geotech amplifier/VCO and discriminator and the L4C vertical seismometer with Tricom amplifier/VCO and discriminator is shown in figure Dl.

Since the vertical-component station amplifiers are higher gain than the horizontal station am­ plifiers, we rely on the horizontal stations to provide ground-motion data for magnitude estimates when the rest of the network is overdriven. Also, it should be noted that both tradition and current usage dictate that ML calculations should proceed from scaled horizontal ground motion; thus, the vertical-instrument amplitudes must be converted to equivalent horizontal motion using a fixed amplification factor (we use h = 1.75v; see Rogers and others, 1987). The horizontal-instrument peak amplitude data now being collected should be helpful to verify or, if necessary, to modify this factor. Perhaps the following detailed information on horizontal station calibrations is therefore warranted.

Field calibrations are performed at the stations every six months or as needed. A field cali­ bration entails applying a known current into a seismometer calibration coil at fixed frequencies, and setting the amplifier/VCO gain so that none of the signals are overdriven (output peak voltage < 5 volts). The signal is monitored on the PDP 11/34 computer at Golden, Colorado, where the digital output ("counts") is reduced to equivalent ground motion. This computed ground motion is compared with the expected ground motion

where y =peak-to-peak ground displacement (m), i 8 = peak-to-peak current input to calibration coil (amps), G c = calibration coil constant (newtons/amp), M transducer mass (kg), and u> = angular frequency of oscillator (radians/sec). If a divergence of > 20% between computed and expected ground motion occurs in the 2 to 10 hz range, the electronics technicians are notified so that further action may be taken. Although 20% may be considered a large error for mag­ nitude calculations, such an error represents a ML variation of « 0.10 units, a small difference. Furthermore, the calculation of expected ground motion involves the factor G c , which may vary by 20% to 30% from the nominal value (0.439) used when no other information is available for a particular L4C seismometer. Table Dl shows percent variation in computed ground motion at various stations using manufacturer's reported values for M and G c where available, or nominal values for M = 0.98 and G c = 0.439 otherwise. The filters used to reduce digital counts to ground motion are discussed in Rogers and others (1987, Appendix A). The 10 hz observed response for L4C seismometers may be a few percent low due to a calibration coil-main coil interaction (in­ ductance), rather than to errors in computed amplification of ground motion. (This interaction is even more pronounced at 20 hz, to the extent that the digital response at that frequency appears 50% lower than expected.)

Table Dl. Percent difference between computed and expected ground motion (Difference(%) = 100 x Comp Etxpe~cfeXdPeCted )' These calibrations were performed in late 1986 and early 1987. There is no observed ground motion during a field calibration, so the tests are indirect.

Frequency (hz)

Figure Dl. - System frequency (amplitude) response of a L4C horizontal seismometer input into a Teledyne-Geotech 4250 amplifier (curve 1) compared to that of a L4C vertical seismometer input into a Tricom 649 amplifier (curve 2), expressed as digital amplification of ground motion (digital counts per meter ground displacement). The seismometer of curve 1 has natural frequency fn = 1.0 hz, h = 0.64 damping, and effective generator constant Gu = 176.7 volt sec/meter, and that of curve 2 has fn = 1.0 hz, h = 0.71, and Gu = 126.5. These are measured values for particular L4C seismometers. The G te s differ because we use different shunt resistors for the two systems. Both amplifiers have 48 dB nominal gain.

APPENDIX E

1984-1986 Focal mechanisms with table summarizing mechanisms computed 1979-1983

The focal mechanisms of Appendix E were obtained by selecting the best-fitting solution(s) from the application of the computer program "FOCMEC" (Snoke and others, 1984) to the ray data generated by HYPO71, and in some instances, to amplitude data. We plot data on the lower focal hemisphere using the equal-area projection (Lee and Stewart, 1979). The symbols represent first-motion P polarities, and their positions represent the points where the HYPO71-determined raypaths intersect the focal hemisphere. The darkened circles represent impulsive compressional arrivals, the + symbols represent emergent compressionals, the open circles represent impulsive dilitationals, the symbols represent emergent dilitationals, and the x symbols represent indeter­ minate or nodal readings. The + symbol at the center of each mechanism is not a compression; it is a point of reference for readers who may wish to search for alternative solutions using a Schmidt net. In the following figures the P and T symbols represent the pressure and tension axes, re­ spectively. The X and Y symbols represent slip vectors for each nodal plane, and B is the null axis. Primed symbols are the respective vectors for alternate (dashed) solutions when they are presented. Some mechanisms are composited using data from several events that are clustered in time and space. Composite solutions are noted in each figure.

For several mechanisms, the information contained in P-wave polarities was not adequate to effectively constrain the nodal planes. In these instances, first motion P- and SV- amplitude data were gathered at selected stations, indicated by a large square around the polarity symbol. The observed and theoretical lo% 10 (SV/P)z ratios and the difference between the logarithms of observed and theoretical ratios are computed for hundreds of potential solutions whose nodal planes conform to P-wave first-motion polarities. The theoretical values shown in each figure are for the "optimum" solution shown, having the lowest rms error and fewest polarity inconsistencies. If the difference between observed and theoretical values is greater than a specified limit, errmal , that station's amplitude data are not used in the solution and an asterisk is placed by its name in the solution table. We always set errmax < 0.3, corresponding to a maximum factor between theoretical and observed amplitude ratios of 2.0.

Kisslinger and others (1981) and Rogers and others (1987) discuss several assumptions that must be satisfied for the (SV/P} X amplitude ratio method to be valid. Their comments and observations are included herein by reference.
