Live Earthquake Tracker

Every significant earthquake on Earth, plotted on a live map within minutes of detection.

The Overseer streams seismic events directly from the United States Geological Survey, placing each quake on the map sized by magnitude. The result is an at-a-glance view of where the planet is shaking right now and how strongly.

Combine the seismic layer with natural-disaster, volcano and weather data to monitor cascading hazards — from aftershock sequences to tsunami-risk coastlines — and adjust the time window to study a developing swarm.
