Overview
- The Instituto Geofísico del Perú’s CENSIS recorded a magnitude 3.6 earthquake 73 km west of Samanco at 06:44 local time on Saturday, October 31, with a focal depth of 35 km.
- Residents in Samanco reported light shaking measured II–III on the Mercalli scale and local authorities confirmed there were no material damages or casualties.
- IGP catalogs show a string of small to moderate quakes across the country in late October, including events in Ica, Puno, Tacna and Ucayali, reflecting the nation’s steady seismic activity.
- Sismologist César Jiménez Tintaya and other experts say the central coast has accumulated tectonic energy since the 1746 megathrust, and they estimate the region could host a future quake in the roughly M8.5–8.8 range though timing cannot be predicted.
- Officials urge relying on IGP/CENSIS data, keeping emergency kits and evacuation plans ready, and watching for updates from INDECI and local authorities as monitoring continues in real time.
