Shallow M5.6 earthquake hits near Puerto Madero, Mexico

A shallow M5.6 earthquake was registered at 12:28 UTC on September 2, 2026, approximately 71 km (44 miles) west-southwest of Puerto Madero, Mexico. The seismic event originated at a depth of 10.0 km (6.2 miles), according to data from the USGS.

The earthquake’s coordinates, 14.4°N and 93.0°W, place the epicenter close to the Pacific coast of southern Mexico, in an area frequently affected by tectonic activity due to its proximity to the Middle America Trench. The region is predominantly rural, with small communities scattered along the coastal and inland areas near Puerto Madero.

Given the vicinity to the Pacific coast and regional transportation links, critical infrastructure that could be present includes local ports, highways, and possibly small energy distribution networks serving nearby towns.

There is no tsunami threat associated with this earthquake, based on its location and available data.

USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity for this earthquake was IV, and the significance index is 482 (on a scale that runs through 1 000), based on magnitude, estimated impact, and available data.

This region of Mexico is seismically active, situated near the convergent boundary where the Cocos Plate subducts beneath the North American Plate. The Middle America Trench is responsible for frequent moderate to strong earthquakes along the coast.
