Existing & Future Earthquake Information Systems Ken Hudnut USGS, Pasadena LA Financial Services Sector Regional Recovery Coalition Meeting 17 November 2005, Los Angeles
Southern California is the nations most dangerous place for earthquakes - why? Since Northridge weve built state-of-the-art earthquake monitoring Arrays. Crucible for technology and earthquake research within SoCals natural laboratory
San Andreas fault 35 mm/yr slip rate; >70% of plate motion 1685, 1857 eqs SoCal is now well wired Likely source of most future Big Ones Fault physics experiment GPS/INS in near-field ALSM & DG scan net Great place to test EEW Build zipper arrays Cholame - Simmler Coachella Valley
Summary Slip sensor concept is to augment regional seismic coverage - one part of an overall EEW system that is primarily using a very different approach Measure slip directly - dont need to know anything else - quick & easy High risk deployment strategy tuned to rare pay-off in extreme events Robust earthquake early warning system design obtain more accurate displacement observations new instrumentation for dynamic and static displacement address deficiencies due to double-integration of accelerometer records Same R&D effort as for DamageMap instrumentation - now under way with USGS Venture Capital and ANSS start-up funds, but major funding and long-term support for implementation has not yet been identified
