The 1964 Guerrero earthquake occurred on July 6 at 01:22 local time in Guerrero, Mexico. The magnitude of this earthquake was given as Ms 7.4,[2] or ML 7.2.[3]

Tectonic setting

In the nearby region, the Cocos plate is subducting beneath the North American plate, however, this was an intraplate earthquake.[4]

Earthquake

The earthquake affected the states of Guerrero and Michoacán. Forty deaths were reported.[5] The most affected places included Ciudad Altamirano, Cutzamala, Coyuca de Catalán, Tanganhuato, and Huertamo.[3] The earthquake was also felt strongly and caused panic in Mexico City.[6]
