Overview
- A series of shallow, small-to-moderate earthquakes was recorded off southern Chiapas between Friday and Sunday, with reported magnitudes ranging roughly from 4.1 to 4.7 and focal depths near 7–15 km.
- The strongest event was a magnitude 4.7 located about 118 km southwest of Huixtla on Saturday, and seismic stations continued to register modest offshore activity through early Sunday.
- State and national Protección Civil teams carried out inspections and reported no injuries or structural damage after the events, and no tsunami alerts were issued.
- Officials said the quakes are consistent with normal subduction-zone activity where the Cocos plate dives beneath Mexico, and they urged the public to follow Servicio Sismológico Nacional bulletins and preparedness measures.
- Separate minor inland quakes in Peru on Saturday included a M3.5 near Cusco and a M3.8 near Ica, both reported by the IGP with no damage reported, underscoring ongoing seismicity along the Pacific margin.
