Watch earthquakes hit a live 3D globe the instant USGS or EMSC detects them — with the distance from you on every quake. Free. Pro adds smart alerts & insights.
The earth is always moving. Tremor shows you where — live, on a 3D globe you can spin.
The moment an earthquake is detected by USGS or EMSC, the global standard for seismic data, it appears on your map instantly. Zoom the globe, watch quakes pulse in as they happen, and see exactly how far each one is from you.
