| Abstract: | On Nov.14, 2001, a M\-S=8.1 earthquake occurred on the western segment of East Kunlun fault, the boundary of Xinjiang and Qinhai. The East Kunlun fault is a huge boundary fault between two blocks. It has the sinistral shearing due to the eastward escaping of the northeastern part of the Tibetan Plateau, which is a famous strong earthquake belt in north Tibetan Plateau. The M\-S=8.1 quake was centered in the conjunction of the NWW-trending East Kunlun fault and a NEE-trending secondary fault. The rupture is mono-propagating from the west to the east. |
