This event is a moderate earthquake measuring 5.1 on the magnitude scale, with a focal depth of 21 km. Events of this magnitude are typically felt over a wide area and may cause damage to vulnerable structures. Calamity.live has classified it as "medium" severity with a severity value of 40.8. The computed Calamity Score is 17 out of 100, suggesting contained impact at this time. The primary scoring components are: historical (80), intensity (22). Data for this event was sourced from usgs, one of the 250 scientific monitoring sources aggregated by Calamity.live.
Regional Monitoring Context
Chile has a documented history of earthquake events. Seismic monitoring in the region draws on data from multiple agencies including USGS, EMSC, and regional networks. Understanding local seismicity helps emergency management agencies plan for potential future events and assess building code adequacy. Earthquake hazard in any region depends on fault proximity, soil conditions, and building vulnerability — factors that can vary significantly even within a single metropolitan area.
