Overview
- Peru’s geophysical institute reported a magnitude 4.0 quake at 01:03 local time on January 14 near Chimbote, Áncash, at a depth of about 48 km with no major damage reported.
- An earlier magnitude 4.8 event was recorded on January 13 roughly 295 km south of Tacna at 138 km depth, rated intensity III in Tacna and causing no reported harm.
- Mexico’s seismic service logged about 20 events early January 13, including a magnitude 4.0 near Pijijiapan, Chiapas, at 16.4 km depth that did not meet the threshold to trigger Mexico City’s seismic alert.
- USGS tallied 17 earthquakes of magnitude 2.5 or higher in the past 24 hours through January 13, with the strongest a magnitude 4.2 in Alaska’s Aleutian region.
- Monitoring and early‑warning systems such as SASMEX and ShakeAlert remain active as agencies share preparedness advice consistent with the tectonic setting of the Pacific Ring of Fire.
