- Abstract:
- On October 2,2014,a MS5.1 earthquake occurred in Wulan,Qinghai province.Using the local broadband waveform data of available stations in regional seismic networks,the focal mechanism and focal depth were determined by the “Cut and Paste”(CAP)method at first.The best double couple solution is 279°,48°,81°for strike,dip and slip angles,respectively for one nodal plane,and 112°,43°,100° for another nodal plane,the estimated focal depth is about 15 km.In order to better constrain the focal depth,we further refined it with depth sPn phase by using the arrival-time differences between Pn and sPn phases,which were picked by the waveform cross-correlation and sliding-window correlation method.The difference between the two methods was within 0.5 meters.
