Abstract:The earthquakes that occurred in the area of Yubei and adjacent region from 1985 to 2008 were relocated with the double difference method and the results of 497 earthquakes were obtained. The result shows that the distribution of relocated epicenters appear zonal,while the earthquakes in a part of areas get close to tectonic belts. The most hypocenter depths in the area distribute mainly within the upper and middle crust. The average hypocenter depth is 13.3 km and the seismogenic layer ranges from 10 km to 20 km.
