Overview
- The Servicio Sismológico Nacional recorded a magnitude 4.1 event near Matías Romero that occurred on July 26 and is listed in the SSN’s official daily reports.
- Seismologists measured the quake’s focal depth at 136 km, a depth that typically reduces the strength of shaking felt at the surface.
- State civil protection teams carried out standard inspections after the detection and reported no significant structural damage or injuries in nearby communities.
- The SSN published an evening report and the full daily dataset with coordinates, times and depths on its website and urged the public to use official SSN and Protección Civil channels for updates.
- The Isthmus of Tehuantepec is a region of frequent tectonic activity, so officials stressed preparedness measures such as emergency kits, evacuation plans and participation in drills as routine precautions.
