Joint inversion with both local and teleseismic waveforms for source parameters of the 2010 Kaohsiung earthquake

We improved the traditional Cut and Paste (CAP) method in inverting point source parameters by combining local Pnl, surface waveforms and teleseismic P and SH waveforms, and then applied the method (CAPjoint) to study the source parameters of the 2010 Kaohsiung earthquake. The result shows that the best double-couple solution of the event is: 317 degrees, 36 degrees, 52 degrees for strike, dip and rake, respectively. The other nodal plane is 181 degrees, 62 degrees, 114 degrees with 21km focal depth. We tested the sensitivities of several parameters for data at different distances with typical mechanisms. Then we applied the bootstrap method to make statistics and verified that the joint inversion method is effective for constraining source parameters of moderate earthquakes, and the effect is especially good when the distribution of local seismic stations is sparse.
