Overview
- The Instituto Geofísico del Perú (IGP/CENSIS) confirmed a magnitude 3.6 quake 37 km west of Huacho at 14:37:59 on Thursday, October 15, located at latitude -11.11 and longitude -77.94 with a depth of 48 km and an intensity of II in Huacho.
- The official report carries the identifier IGP/CENSIS/RS 2026-0735 and authorities said there were no immediate reports of material damage or casualties following the event.
- Sismologist César Jiménez Tintaya of UNMSM warned that central Peru has accumulated tectonic energy since the 1746 megathrust and estimated past 20th and 21st-century quakes have released about 20% of that energy, a figure he said could allow for a future megathrust event in the long term.
- The October 15 quake followed a similar magnitude 3.6 tremor recorded the night before near Chosica, illustrating continued low‑level seismic activity and the IGP’s close monitoring of small events.
- Civil‑defense agencies urged residents to review emergency plans, keep a ready emergency kit and follow official channels for updates because preparedness reduces harm to people and infrastructure if a larger event occurs.
