Improving Epicentral and Magnitude Estimation of Earthquakes from T Phases by Considering the Excitation Function

Abstract

A standard technique for locating events with T phases is to pick the peak energy of T phases as the arrival time, then proceed as if it was an unscattered phase originating at the epicenter. The peak energy arrival time, however, can shift to different parts of the wave train due to incoherent scattering. We show that a 50% reduction in variance relative… (More)
