The April 18, 2014 M 7.2 earthquake near the Pacific coast of Mexico occurred in the state of Guerrero, 265 km southwest of Mexico City. The earthquake occurred as the result of thrust motion at shallow depths. The initial location, depth, and mechanism of the April 18 earthquake are broadly consistent with slipping on or near the plate boundary interface between the subducting Cocos oceanic sea plate and the North America plate. The broad scale tectonics of the Pacific coast of Mexico are controlled by the northeastward subduction of the Cocos plate beneath the North America plate at the rate of approximately 65 mm/yr. Earthquakes are a common occurrence along the Middle American subduction zone.
