A magnitude 7.3 earthquake struck off the coast of Chiapas, Mexico, near the border with Guatemala, triggering temporary tsunami alerts across the Pacific. While the United States tsunami warning system briefly flagged a risk for coastal areas within a 300-kilometer radius, authorities deactivated the alert within an hour. Mexican President Claudia Sheinbaum and the President of Guatemala have confirmed there are no immediate reports of casualties or structural damage, though emergency protocols remain active in both nations.
Earthquake Impact and Immediate Emergency Response
The seismic event occurred at a depth of 15 kilometers, with its epicenter located near the coast of Chiapas. According to the Mexican government, the tremor was felt significantly across various buildings in the region, prompting residents to evacuate homes, offices, and commercial spaces. In the tourist destination of San Cristóbal de Las Casas, residents gathered in open streets while local authorities conducted safety assessments.

The Secretaría de Protección Civil of Chiapas has deployed monitoring teams to evaluate the integrity of basic services and infrastructure. Officials are urging the public to check gas and electrical installations and to report any hazards to the 911 emergency line. President Sheinbaum stated via social media that she has been in direct communication with the governors of Chiapas and Tabasco to coordinate preventive measures and structural inspections.
Tsunami Risk Assessment and Regional Alerts
The United States tsunami warning system initially projected that waves between 30 centimeters and one meter could hit the coastlines of Mexico and Guatemala. For neighboring nations, including Colombia, Costa Rica, and Ecuador, the system anticipated wave heights would not exceed 30 centimeters.
