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.
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.

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.

| Volcano | Color Code | Alert Level | Observatory | Notice |
|---|---|---|---|---|
| Great Sitkin | ORANGE | WATCH (was ADVISORY) | Alaska Volcano Observatory | Notice |
Slow eruption of lava within the summit crater continues, with weak seismicity and steaming. | ||||
| Kilauea | ORANGE | WATCH (was ADVISORY) | Hawaiian Volcano Observatory | Notice |
Kīlauea volcano is intermittently erupting short, precursory lava flows continuing the activity that began September 7. The forecast window for onset of episode 55 fountaining is now September 10-11 given no change in summit inflation since yesterday. | ||||
| Shishaldin | YELLOW | ADVISORY (was NORMAL) | Alaska Volcano Observatory | Notice |
Low-level seismic unrest continues, with weak seismicity and a summit gas plume. | ||||
| Ahyi Seamount | YELLOW | ADVISORY (was UNASSIGNED) | Northern Mariana Islands | Notice |
Faint water discoloration seen in satellite images; no significant geophysical signals. | ||||
