Overview
- USGS reported a magnitude 5.1 quake near Calana in northern Chile while Chile's Centro Sismológico Nacional gave the same event as magnitude 4.9 with a nearer, shallower epicenter.
- Peru's Instituto Geofísico del Perú (IGP) recorded a M3.5 event near Lurín in Lima and two M3.4/M3.3 quakes near Huasicancha in Junín, all of which were felt but caused no reported damage.
- The different agency readings reflect routine variation in seismic analysis because depth and epicenter estimates change how strong shaking is felt and how hazard is assessed.
- Experts say these recent small quakes do not indicate immediate destruction but highlight longer-term risk, with a UNMSM sismologist estimating only about 20 percent of the region's accumulated seismic energy has been released since 1746.
- Authorities and media have urged basic preparedness steps such as emergency kits and identified safe zones while seismic services continue to monitor the subduction zone for larger events.
