Text
Summary of Preliminary Findings from the USGS/PG&E hazard studies for the Central Coastal California Region Seismicity data from the USGS: J. Hardebeck, Areo-magnetic data from V. Langenheim, Marine-magnetic data from J. Watt
Regional Seismicity Based on Local Velocity Model Double-difference Tomography (tomoDD):
- solves jointly for velocity model and earthquake locations
- absolute and relative arrival times
- improves both absolute and relative earthquake locations Earthquake Data:
- ~1400 earthquakes (exclude San Simeon aftershocks)
- ~26,000 P-wave and ~3000 S-wave absolute arrival times
- ~11,000 P-wave and ~5000 S-wave relative arrival times from waveform cross-correlation
Focal Mechanisms Ray tracing in 3D velocity model.
Black: good quality (A-C of Hardebeck & Shearer) single-event mechanisms.
G l
lit i
l t
Grey: lower quality single-event mechanisms, checked for reasonableness.
Red: composite mechanisms.
