A strong 7.3 quake struck off southern Mexico’s coast, prompting a tsunami warning but no casualties or major damage were reported.

A powerful 7.3‑magnitude earthquake hit off the coast of southern Mexico on Friday, triggering a tsunami warning for nearby Pacific shores. The tremor left no fatalities or major damage in Mexico, Guatemala or El Salvador, though residents were urged to avoid beaches. Aftershocks ranging from 4.7 to 6 were recorded, and authorities advised coastal communities to remain alert. The US Geological Survey cited a shallow depth of 15.2 km, and NOAA warned of up to 0.3‑meter waves along several Central American coastlines. Local leaders have called for calm and adherence to safety guidance.

7.3‑Magnitude Earthquake Strikes Southern Mexico Coast

A powerful 7.3‑magnitude earthquake struck off the coast of southern Mexico on Friday at 08:49 local time, just 15.2 km beneath the surface. The U.S. Geological Survey (USGS) identified the epicentre near the fishing town of Puerto Madero.

The quake triggered a tsunami warning for parts of the Pacific coast, but the US National Oceanic and Atmospheric Administration (NOAA) later recorded waves of only about 0.3 metres (1.1 feet) above sea level in Puerto Madero and Chiapas.

Officials in Mexico reported no significant damage or casualties. Mexico’s navy secretary, Admiral Raymundo Morales, urged people to stay away from beaches while the nation remained on alert. Governors from Oaxaca and Chiapas also called for temporary suspensions of administrative and private‑sector activities to ensure safety.

In neighboring countries, the tremor caused buildings to shake and prompted evacuations in Guatemala and El Salvador. Guatemala’s President Bernardo Arévalo declared an emergency response to a 5.6‑magnitude quake that had its epicentre in Quetzaltenango, with no fatalities yet.

After the initial alert, a series of aftershocks ranging from 4.7 to 6.0 were logged. Authorities advised residents in affected coastal regions to remain observant and follow local instructions.

No damages or fatalities were reported, but the event highlighted the importance of preparedness for seismic and tsunami threats along the Central American Pacific rim.
