Validation And Update Of Hybrid Empirical Ground Motion (Attenuation) Relations For The CEUS, USGS Award Number: 05HQGR0032

September 2007
Ground motion models are the most common means of calculating peak ground motion parameters and response spectra in engineering practice. Where strong motion recordings are abundant, these models are empirically derived. Where the number of recordings is limited, they are developed typically from seismological models and constrained using weak motion data. This technical report for 05HQGR0032 is posted on USGS website.

Time-independent and Time-dependent Seismic Hazard Assessment for the State of California: Uniform California Earthquake Rupture Forecast Model 1.0

January/February 2007
Ground-shaking hazard maps based on sound earth-science research are effective tools for mitigating damage from future earthquakes.

Loss Estimates for a Puente Hills Blind-Thrust Earthquake in Los Angeles, California
Kenneth W. Campbell of EQECAT, Hope Seligson of ABS Consulting, Coauthors
EERI paper that estimates losses due to a large earthquake on the Puente Hills fault using the publically available HAZUS loss-estimation software. These losses are not necessarily what our USQUAKE software would estimate, but SCEC required that we use publically available software for the project. This work is part of our continuing involvement in Southern California Earthquake Center (SCEC) research projects.

Time-Dependent Earthquake Ruptures And Southern California Earthquake Risk- EQECAT Comments On Current Published Research Regarding Southern San Andreas Earthquake Near-Term Rupture Probabilities
June 2006
A recently published study into earthquake seismology in California highlights the increased near-term probability of large earthquakes along the Southern California San Andreas Fault (SAF) system. This earthquake source represents a very real risk to the residents of Southern California and this study re-affirms the earthquake hazard model incorporated into the EQECAT earthquake risk model.
