Overview
- The Instituto Geofísico del Perú’s bulletin confirmed a magnitude 3.6 quake on Thursday, October 15 that occurred 37 km west of Huacho at 14:37 with a focal depth of 48 km and an estimated Mercalli intensity of II in Huacho.
- IGP reports a separate magnitude 4.1 event on Saturday, October 17 that affected Piura but had its epicenter in Ecuador about 104 km northeast of Ayabaca at a depth of 100 km and caused no reported damage.
- CENSIS data show a cluster of small-to-moderate quakes across regions including Lima, Junín, Huánuco, Pasco and Arequipa over the past week as the national seismic network maintains active, real-time monitoring.
- Sismologist César Jiménez Tintaya warned that the central Peruvian coast has accumulated strain since the 1746 megathrust quake and said historical releases have removed roughly 20 percent of the energy, leaving the longer-term possibility of a much larger event.
- Civil‑defense authorities urged residents to keep emergency backpacks, identify safe zones and review family evacuation plans as a practical response that could reduce harm and prompt more local drills and infrastructure checks.
