Overview
- The Instituto Geofísico del Perú (IGP) confirmed a magnitude 3.6 quake occurred 37 km west of Huacho at 14:37:59 on Thursday, October 15, at a depth of 48 km and was felt with intensity II in Huacho with no reported damage.
- IGP/CENSIS is publishing near‑real‑time logs of multiple small‑to‑moderate quakes across Lima, Arequipa, Piura and other regions during mid‑October to track ongoing seismicity and guide civil protection responses.
- Sismologist César Jiménez Tintaya told reporters that accumulated tectonic energy since the 1746 megathrust event could allow a future earthquake in the central coast region in the magnitude 8.5–8.8 range, a long‑term assessment rather than a prediction.
- Japan’s Meteorological Agency has apologized and opened an investigation after its system mislocated and overestimated a Kamchatka event, briefly issuing a false M9.9 alert and then retracting it, underscoring limits of automated early‑warning formulas for distant quakes.
- Other recent international events reported by agencies include a USGS‑listed M5.7 in southeast Pakistan and a Mexican quake revised from M5.4 to M5.1 by CNPC, with initial inspections from local authorities reporting no casualties.
