lang=EN-US>Analyses based on investigation of the seismic intensity and digital seismic data by mobile observation on-site from the Yao’an M 6.0 Earthquake occurred on 9th July 2009 in Yao’an County, Yunnan Province, and on the spatial distribution of earthquake sequences, focal mechanisms, and intensity distribution of other three earthquakes occurred since 2000 in the same area with the similar magnitude, show that there are obviously different characteristics in earthquake focal depth, direction of the long axis of isoseismal lines, major trend of sequence spatial distribution, and so on of the four earthquakes. Comprehensive analyses combined with data from petroleum seismic exploration show that the regional seismotectonic setting is very complicated, featured by seismotectonics interweaved with different strikes and faulted structures coupling at different depths in Yao’an area.
