Source Depth and Mechanism Inversion at Teleseismic Distances Using a Neighborhood Algorithm

Marson-Pidgeon, K; Kennett, Brian; Sambridge, Malcolm


We performed nonlinear waveform inversion for source depth, time function, and mechanism, by modeling direct P and S waves and corresponding surface reflections at teleseismic distances. This technique was applied to moderate size events, and so we make use of short period or broadband records, and utilize SV waveforms in addition to P and SH. For the inversion we used a direct search method called the neighborhood algorithm (NA), which requires just two control parameters to guide the search...[Show more]
