CHIAPAS, MEXICO / RankWire.AI / – A magnitude 7.3 earthquake impacted off the southern Pacific coast of Mexico on Friday, causing strong tremors throughout Chiapas and neighboring nations. The U.S. Geological Survey pinpointed the epicenter approximately 48 kilometers southwest of Aquiles Serdán. The quake was registered at a depth of 15.2 kilometers. It occurred at 8:48 a.m. local time, or 14:48 UTC. Authorities reported two injuries but no fatalities or significant structural damage.
Emergency response teams promptly began inspections across southern Mexico after the tremors subsided. In Tapachula, a woman jumped about four meters from an apartment building during the quake. She sustained fractures and was hospitalized. Officials stated her condition was not life-threatening. Another individual suffered a minor injury from broken glass inside a commercial premises. Civil protection units examined homes, schools, hospitals, roads, and public buildings for cracks, debris, or other signs of damage.
Residents experienced the earthquake across southern Mexico, Guatemala, and El Salvador. The shaking was also felt in Mexico City, hundreds of kilometers away from the epicenter. Workers evacuated offices and other structures in Guatemala City as the tremor intensified. Mexico City’s seismic alarm did not activate because early energy measurements remained below the activation threshold. Authorities in affected regions set up emergency assessment routes and requested reports of damaged structures, blocked roads, and unsafe utility lines.
Tsunami warning concludes after shoreline assessments
The Pacific Tsunami Warning Center initially issued a warning 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 while the warning was active. Instruments at Puerto Madero recorded a sea-level rise of about 0.3 meters. The center later lifted the tsunami alert after reviewing observations from the affected shoreline.
The main quake was preceded by a smaller offshore tremor and was followed by several strong aftershocks. Initial data recorded at least 10 aftershocks with magnitudes between 4.9 and 6. Guatemala activated national emergency protocols and inspected western departments near the Mexican border. Education authorities suspended in-person classes in San Marcos, Quetzaltenango, Suchitepéquez, and Retalhuleu. Road crews also examined reports of minor landslides and debris along routes in western Guatemala.
Authorities report minimal regional destruction
Mexican President Claudia Sheinbaum stated that initial evaluations revealed no significant damage. Navy Secretary Admiral Raymundo Morales also reported no severe impact from the quake. Officials in Oaxaca mentioned residents experienced moderate shaking without major damage. Local authorities continued inspecting bridges, hospitals, schools, and utility networks. Emergency officials advised the public to adhere to safety instructions during aftershocks and to avoid compromised structures until trained inspectors completed assessments.
The earthquake occurred along a highly active fault boundary where the Cocos Plate subducts beneath adjacent tectonic plates. This region generates frequent seismic activity along Mexico’s southern Pacific coast. By Saturday, authorities confirmed two injuries and no fatalities. Mexico, Guatemala, and El Salvador had not recorded widespread structural damage. Coastal monitoring indicated no ongoing tsunami threat. Seismic agencies continued to track aftershocks and update technical data as regional inspections proceeded.
