The 1965 Oaxaca earthquake occurred in Mexico on August 23 at 13:46 with a moment magnitude of 7.5.[1][2] Five people were reported dead in Mexico City and one in Oaxaca. There was an anomalous change in seismic activities before the earthquake. There was a quiescent stage from late 1963 to mid-1964, and it was followed by a renewal of seismic activities before the main shock.[3] This earthquake was a shallow thrust earthquake in the interplate subduction zone, in which the Cocos plate is subducting beneath the North American plate.[4][5]
