1994 Northridge Earthquake 2

Lecture Objectives-hazard map predictions-mitigation lessons learned

Notes from:http://greenwood.cr.usgs.gov/pub/open-file-reports/ofr-96-0263/

Mercalli Index Quiz

-At what level does considerable damage to structuresoccur?

-Give an example of how the Mercalli Index can be used forearthquake hazard studies.

Why?

8 seconds duration

Los Angeles Region Seismic Experiment (LARSE): seismicrefraction study to study subsurface

Seismic reflection

A planner’s nightmare

Landslide locations: cut off roads, pipelines; dammed streams;secondary result produced increased valley fever cases

Trenching: mapping displacements from historic activity;determine frequency, magnitude, type

PGA= Peak Ground acceleration

Summary

-seismic energy focused in many (predictable) ways-mitigation must prepare for localized regions of intense

shaking-need to consider blind faults in hazard mapping-utility of shaking intensity maps: a GIS application of

tagging damaged structures-mitigation engineering: soil treatments, structural

foundation isolation-development of broadcast system following seismic events-special effects of public education: seismic hazard
