Overview
- The Instituto Geofísico del Perú (IGP) recorded a magnitude 5.9 quake about 102 km west of San Juan de Marcona at a depth near 32 km, and residents in Ica reported the shock.
- Friday’s M5.9 was the largest in a cluster of moderate events this week that included several M4–4.8 tremors across Huánuco, Loreto, Pasco and a separate M5.2 on the Chile Ridge reported by the USGS.
- Seismological agencies note initial magnitude and location values are provisional and may be revised after station data are processed, and Chile’s CSN and the USGS sometimes publish differing parameters for the same events.
- No casualties, material damage or tsunami alerts have been reported so far, and maritime authorities confirmed the Ica event did not trigger a coastal tsunami warning.
- Sismologists say the central coast has long-accumulated tectonic strain since the 18th century, which keeps the region at elevated risk and explains official calls for emergency kits, evacuation plans and continued monitoring.
