基于地震波反演的地震震源深度研究
Study on Focal Depth from Local Broadband Waveform Data Inversion
摘要
Abstract
Based on the records of regional seismic networks, we obtained the focal mechanism and focal depth of Diebu Ms 4.0 earthquake on Feb 23, 2011, with the "Cut and Paste" (CAP) method. Then using depth phase sPg and reference phase Pg, we analyzed the focal depth in detail. The results show that the best double solution for this Diebu earthquake is 110°, 57° and 23° for strike, dip and slip angles respectively, which belongs to the strike-slip type with a little thrust weight and is 7 km in focal depth. Through comparing the theoretical and the observed seismograms of HZT station, we confirm the reliability of the focal depth.关键词
