Tectonic setting[edit]

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


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]


Coyuca de Catalán was seriously damaged. The city hall was destroyed. The majority of the houses there were seriously damaged and became uninhabitable. There were great cracks on the ground.[7]
