Overview
- The SSN recorded the quake at 00:06 on December 25, locating the epicenter 64 km south of Ciudad Hidalgo, Chiapas, at a depth of 59.3 km.
- Authorities reported no material damage or emergencies and confirmed the seismic alert was not activated, though some nearby residents felt brief, light shaking.
- Under SASMEX criteria, alerts depend on both distance and magnitude, and a 4.1 event at this location falls below the activation thresholds.
- Mexico’s south and southeast experience frequent tremors due to interaction between the Cocos and North American plates, a pattern experts describe as normal.
- A day earlier, the SSN logged a magnitude 4.0 west of Río Grande, Oaxaca, and a 4.3 southwest of Ciudad Hidalgo, and officials reiterated standard Protección Civil safety guidance.
