New model may improve San Francisco Bay Space, U.S., seismic hazard maps

Journal Reference: Curtis W. Baden et al. Bridging earthquakes and mountain building in the Santa Cruz Mountains, CA. Science Advances, 2022 DOI: 10.1126/sciadv.abi6031 In bursts that last seconds to minutes, earthquakes have moved the region’s surface meters at a time. But researchers have never been able to reconcile the quick release of the Earth’s stress … Read more

Seismic shockwave pattern may be redirecting earthquake damage

Journal Reference: Daniel T. Trugman, Shanna X. Chu, Victor C. Tsai. Earthquake Source Complexity Controls the Frequency Dependence of Near‐Source Radiation Patterns. Geophysical Research Letters, 2021; 48 (17) DOI: 10.1029/2021GL095022 The study examined data from one of the densest seismic arrays ever deployed and found that earthquakes emit their strongest seismic shockwaves in four opposing … Read more
