CHIAPAS, MEXICO / RankWire.AI / – A magnitude 7.3 earthquake impacted off Mexico’s southern Pacific shoreline on Friday, causing strong tremors that affected Chiapas and neighboring nations. The U.S. Geological Survey pinpointed the epicenter roughly 48 kilometers southwest of Aquiles Serdán, with the quake occurring at a depth of 15.2 kilometers. The seismic event took place at 8:48 a.m. local time, or 14:48 UTC. Authorities confirmed two injuries but reported no fatalities or significant structural damage.
Emergency response teams promptly conducted inspections across southern Mexico after the tremors ceased. In Tapachula, a woman leapt approximately four meters from an apartment building amidst the quake. She sustained fractures and was hospitalized, though her condition was not life-threatening. Another individual was slightly injured by shattered glass inside a commercial establishment. Civil protection units examined homes, schools, hospitals, roads, and public facilities for cracks, debris, and other signs of damage.
The tremor was felt throughout southern Mexico, Guatemala, and El Salvador. Even Mexico City, located hundreds of kilometers from the epicenter, experienced the shaking. Workers evacuated offices and buildings in Guatemala City as the seismic activity intensified. Mexico City’s seismic alert system did not activate due to early energy readings remaining below the activation threshold. Emergency services in affected areas established assessment routes and requested residents to report any damage to structures, blocked roads, or unsafe utility lines.
Tsunami warning concluded after shoreline evaluations
The Pacific Tsunami Warning Center initially issued a warning indicating that waves between 0.3 and one meter could impact parts of Mexico and Guatemala. Mexican naval authorities advised people to stay away from beaches for six hours. Coastal teams monitored communities near Puerto Madero and Suchiate during the active warning. Instruments at Puerto Madero recorded a sea level rise of approximately 0.3 meters. The center later lifted the tsunami alert after analyzing observations from the affected shoreline.
The main quake was preceded by a smaller offshore tremor and was followed by multiple strong aftershocks. Early data recorded at least 10 aftershocks with magnitudes ranging from 4.9 to 6. Guatemala activated national emergency protocols and inspected western departments near the Mexican border. Educational authorities suspended in-person classes in San Marcos, Quetzaltenango, Suchitepéquez, and Retalhuleu. Road crews also responded to reports of minor landslides and fallen debris along routes in western Guatemala.
Regional damage reported as limited
Mexican President Claudia Sheinbaum stated that initial evaluations revealed no major damage. Navy Secretary Admiral Raymundo Morales also confirmed there were no serious impacts from the quake. Officials in Oaxaca reported residents experienced moderate shaking without significant damage. Local authorities continued inspections of bridges, hospitals, schools, and utility infrastructure. Emergency officials advised the public to adhere to safety guidelines during aftershocks and to avoid compromised buildings until trained inspectors could verify their structural integrity.
The seismic event took place near a highly active tectonic boundary where the Cocos Plate subducts beneath neighboring plates. This zone is known for frequent seismic activity along Mexico’s southern Pacific coast. By Saturday, authorities confirmed two injuries and no fatalities. No widespread structural damage was reported in Mexico, Guatemala, or El Salvador. Coastal monitoring indicated no ongoing tsunami threat. Seismologists continued to record aftershocks and update technical data as regional assessments proceeded.
