Each circle is one earthquake — larger and redder means stronger. Switch the data source between USGS and EMSC (two independent real-time global agencies), the stored Nepal Catalogue (every M4.5+ event since 1911, from USGS), and Notable historic events. Use the Layers control to overlay a density heatmap and the India–Eurasia tectonic plate boundary. Click any circle or list item for details and its official USGS or EMSC report.
Live data updates continuously from the USGS Earthquake Hazards Program. This is monitoring of events that have already occurred — not a prediction or early-warning system.
