Tectonic setting edit

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

Earthquake edit

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]

Damage edit

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]
