四川长宁地区ML 4.0以上地震震源机制解及震源深度反演
Inversion of focal mechanism and focal depth of the earthquakes more thanML4.0 in Changning, Sichuan Province
摘要
Abstract
From January to November, 2013, ifve timesML≥4.0 earthquakes happened in Changning district, Sichuan Province. Using the near earthquake wave data of digital seismic network of Sichuan Province, and using CAP method, the focal mechanism of these earthquakes are inverted. The result showed that: The dislocation type of these seismogenic faults belongs to the reverse fault; the dip angle of Principal compressive stressP axis is smaller; the focal dept of these earthquakes depth are shallow; with best depth range of 3-5 km.关键词
