Overview
- A powerful earthquake struck off southern Mexico on Friday with initial readings near 7.4 later revised to 7.3 and a shallow depth of about 10 kilometres centered near Puerto Madero and Aquiles Serdán.
- Tsunami alerts covered coasts within roughly 300 kilometres of the epicentre with forecast sea rises of about 0.3 to 1.0 metre for some beaches and the Mexican Navy saying levels were not expected to exceed roughly 0.5 metre.
- Seismic agencies recorded many aftershocks after the main tremor, with some reports of dozens of aftershocks and a few in the mid-6 magnitude range.
- Authorities ordered building and beach evacuations across Chiapas, Oaxaca and neighbouring Central American areas, and initial inspections found only a handful of injuries and no confirmed major damage or deaths.
- Emergency teams continue ground checks and sea‑level monitoring while officials note that the region sits on an active subduction zone that routinely produces strong shallow quakes and local tsunami threats.
