The 1965 Oaxaca earthquake occurred in Mexico on August 23 at 13:46 with a moment magnitude of 7.5. Five people were reported dead in Mexico City and 1 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. This earthquake was a shallow thrust earthquake in the interplate subduction zone, in which the Cocos Plate is subducting beneath the North American Plate.
