SOUTHERN CALIFORNIA EARTHQUAKE CENTER Southern California: A Natural Laboratory for Earthquake Science SCEC annual meeting, 2000
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Motivations • • Economic Geologic Seismic Historic Knowledgeable and interested public & Media Data availability Problem definition Export of know-how • The beach
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Geologic • Complex Plate Boundary deformation zone on land • Continental breakup • Varied tectonic regimes, major geologic transitions • Good geologic exposure, well mapped • Numerous sedimentary basins • All types of faulting, including mature fault zones (SAF) and immature ones
SOUTHERN CALIFORNIA EARTHQUAKE CENTER We have faults
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Seismic • Region of active seismicity (300+ active faults mapped) • Good instrumental coverage • Good history (450, 000 event catalog, 65 year coverage) • Good paleoseismic record • Numerous well mapped surface breaking events • 30, 000 well-constrained focal mechanisms • High quality digital data • Good access (data centers)
SOUTHERN CALIFORNIA EARTHQUAKE CENTER We have earthquakes
SOUTHERN CALIFORNIA EARTHQUAKE CENTER We have data • • • Seismic (include Strong Motions) Geodetic (GPS) Geologic (177 trenches so far) In. SAR Strain, lidar, remote sensing, etc. Socio-economic
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Economic Motivation • 20 million people • 7 th economy in the world • Major harbors, airports, freeways, lifelines, etc • Major heavy and light industry • Variety of building types • More than hazards…. there is Risk
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Earthquake Risk in Southern California 20 Million people + 7 th largest economy + Active plate boundary + Over 300 active faults = _______________ Almost half the national earthquake risk, with 25% in Los Angeles County alone. . .
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Larger Earthquakes 1932– 1997
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Does this Natural laboratory have the right size? • Outer scale comparable to large earthquake fault dimension • Outreach works well with a self-contained community • Knowledgeable and interested public & media – Cultural, socio-economic needs
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Simulations of San Andreas Ruptures (Olsen, 2000)
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Scientific Critical Mass • • • 10 Institutions of higher learning Research, Students 150 scientists work at SCEC USGS, CDMG, NASA presence Excellent computing and communication infrastructure • Collaborators worldwide
SOUTHERN CALIFORNIA EARTHQUAKE CENTER Exporting know-how • • Model for Outreach Model of instrumentation Model for open data Model for sharing instruments
