Abstract Based on the research of the Ms5.1 earthquake sequence in Badong, the earthquake sequence belongs to the main shock type. The frequency and magnitude of the aftershocks were attenuated ups and downs. Ms5.1 earthquake event located in NEE direction near the southen tip of
Gaoqiao fault and Daping fault,at a depth of 5 to 7 km, tectonic earthquake. According to the results of earthquake precise positioning, the hypocenter parameter analysis and focal mechanism solutions,it is concluded that the earthquake is a stereotype reservoir earthquake, caused by fault tectonic stress adjustment, and triggered under the condition of reservoir high water impoundment (high stress).
Key words :
earthquake sequence
precise positioning
source body
spectrum
focal mechanism solution
