Regional Network focal mechanism determination using 3D velocity model and<i>SH/P</i>amplitude ratio

Abstract High-quality focal mechanisms within the Taiwan Seismic Network are determined utilizing first motions, SH/P amplitude ratios, and hypocentral locations obtained in a joint tomographic inversion. The small-to-moderate (2.7 ≦ ML ≦ 5.7) events, ranging in depths from 3 to 43 km, occurred in t... View More
