This earthquake was caused by the Juisui Fault with a vertical movement of 70 centimeters (28 in).[5][6] The Juisui Fault is a segment of the 150 kilometers (93 mi) long Longitudinal Valley Fault, which is a left-lateral fault with a reverse component.[7] The boundary between the Eurasian plate and the Philippine Plate lies along the Longitudinal Valley Fault.[8]
