Earthquake off Mexico's Pacific coast triggers tsunami warnings for Mexico and Guatemala

USGS recorded a Mexico-associated earthquake on July 13, 2026, at 18:19:59 (UTC-7). The New York Times reported on July 17 that the event triggered tsunami warnings affecting both Mexico and Guatemala. The region sits along the Middle America Trench, where the Cocos Plate subducts beneath the North American and Caribbean plates — a tectonic setting capable of producing tsunamis that propagate southeast toward Guatemala's Pacific coast.
