Overview
- National observatories in Peru, Chile, the United States and Mexico have continued to publish numerous small-to-moderate earthquakes in official catalogs, with entries updated through October 25–26, 2026.
- The Instituto Geofísico del Perú and Chile’s Centro Sismológico Nacional reported multiple recent events including a M3.6 near Santa María de Nieva and several shallow quakes near Ollagüe and Socaire.
- United States Geological Survey and Mexico’s Servicio Sismológico Nacional maintain live catalogs that feed public maps and technical records used by scientists and officials to refine parameters.
- Agencies warn that first-posted magnitudes, depths and epicenters are preliminary and can change as more seismic signals are processed, so initial reports are subject to revision.
- Civil-protection bodies emphasize that limited alert activations reflect technical thresholds in systems like SASMEX and advise households to follow simple preparedness steps such as emergency plans, evacuation routes and ready kits.
