The 1997 Manyi earthquake occurred on November 8 at 10:02 UTC. The epicenter was in Nagqu Prefecture in northern Tibet, China. The focal mechanism indicates a left-lateral strike-slip movement. This earthquake had a surface rupture of 17km (11miles) long with up to 7m (23feet) of left-lateral slip along the Manyi fault, a westward continuation of the Kunlun fault, offset about 100km (100miles) to the south. Normally, the continental crust is about 35km (22miles) thick, but it reaches 70km (40miles) thick under the Tibetan Plateau. This earthquake ruptured up to 20km (10miles) of the top part of the local continental crust.
