- The Servicio Sismológico Nacional recorded a magnitude 4.5 at 05:56 and a magnitude 4.4 at 06:14 on Wednesday, both shallow events off Ciudad Hidalgo measured at roughly 10–15 kilometers depth.
- The first quake had an epicenter about 38 km west of Ciudad Hidalgo (coords 14.64, -92.50) and the second about 121 km southwest (coords 14.27, -93.20), according to preliminary SSN reports.
- No verified reports of significant structural damage or injuries have emerged and local services and transport were reported operating normally in the affected municipalities.
- Protección Civil and local emergency units are conducting building checks, monitoring for replicas, and urging residents to verify their homes and follow official SSN and Protección Civil channels for updates.
- Chiapas lies on the boundary where the Cocos plate interacts with the North American plate, a tectonic setting that explains the region's frequent shallow quakes and the routine use of sensor data that may be refined after analysis.
