Overview
- A magnitude 4.0 earthquake struck Loreto at 1:38 p.m. on Friday, October 23, 2026, with an epicenter 125 kilometers northwest of Andoas and a depth of 141 kilometers, the Instituto Geofísico del Perú reported.
- Defensa Civil and the Centro de Operaciones de Emergencia Nacional said there are no reported injuries or material damage and that they remain on alert and monitoring for developments.
- Sismologist César Jiménez Tintaya told reporters that the central coast has accumulated seismic energy since the 1746 megathrust and that 20th‑ and 21st‑century quakes have released only about 20 percent of that energy, which he says leaves the potential for a much larger future event.
- The IGP continues to publish routine seismic bulletins with magnitude, depth and location data, and INDECI has circulated its emergency 'mochila' checklist calling for food, water, a first‑aid kit, blankets, communication tools and pet supplies.
- Because the recent quake produced no damage, the practical concern for residents is preparedness; watch for IGP updates or aftershock bulletins and keep emergency kits and family plans ready.
