Overview
- The IGP reported a magnitude 5.1 offshore southwest of Pisco in Ica, and it kept coastal monitoring active through its national seismic network.
- The Lima region also saw a magnitude 3.7 off Huacho on Wednesday, measured at 43 km deep and felt at II–III intensity in town, with no damage reported.
- Mexico’s SSN logged a magnitude 4.2 southwest of Pijijiapan, Chiapas, and Protección Civil reported no injuries or damage so no seismic alert sounded.
- A separate magnitude 4.1 near Ciudad Hidalgo, Chiapas, was too small to trigger the public alert, which typically activates for larger quakes that pose risk.
- Mexico’s First National Drill will use a hypothetical magnitude 8.2 off the Guerrero coast, and alerts will sound only in localities that have SASMEX sensors and speakers.
