Abstract
A method estimating the stress level in the focal region of an earthquake is proposed here. Taking the 2001 M=8.1Western Kunlun Mountain Pass earthquake as an example, we estimate its stress level in the focal region before and after it by this method. The results show that the stress level in the focal region just prior to the initiation of this event is approximately 6.3～8 MPa, and about 5～6.7 MPa remained in the focal region after its occurrence. The stress in the focal region decreased by roughly twenty percent after this event.关键词
