Overview
- The Instituto Geofísico del Perú’s Centro Sismológico Nacional confirmed a magnitude 3.6 quake occurred 73 km west of Samanco, Áncash at 06:44 local time on Saturday, October 31, 2026, with a focal depth of 35 km and intensity II–III reported in Samanco.
- Local authorities and initial reports from multiple news outlets say there are no material damages or casualties and that national monitoring remains active following the event.
- Sismologists including César Jiménez Tintaya warn the central coast has accumulated large amounts of seismic energy since the 1746 megathrust quake and estimate the region could still produce a very large earthquake in the future.
- The IGP and emergency agencies are urging citizens to follow official channels for updates, keep family emergency plans current, prepare an emergency kit, know evacuation routes, and use emergency numbers such as Bomberos 116, Policía 105 and SAMU 106.
- October has seen frequent moderate quakes across Peru, recorded by the IGP in regions such as Ica, Ucayali and Puno, a pattern driven by Nazca Plate subduction beneath the South American Plate that keeps seismic risk high and warrants vigilance for stronger events.
