Volcanoes and Earthquakes
Earth is a restless planet. Beneath our feet, tectonic plates grind against one another, magma surges toward the surface, and the ground shakes with energy released from hundreds of kilometers below. This site brings together the best available open data to help you explore that activity — from the ancient calderas of the Pleistocene to volcanoes erupting right now.
Volcanoes
The Smithsonian Global Volcanism Program (GVP) maintains the world's most comprehensive catalog of volcanic activity — more than 2,600 volcanoes documented across the Holocene and Pleistocene epochs, with eruption histories stretching back thousands of years.

Earthquakes
The USGS Earthquake Hazards Program monitors seismic activity globally. This site tracks significant earthquakes and identifies those occurring within 50 km of a known volcano — a relationship that can signal volcanic unrest.
