Underwater volcanoes are powerful geological forces shaping our planet and oceans. These hidden giants form through tectonic ...

Some scientists think we can better understand volcanoes by learning how the gaseous vortexes emerge. By Carolyn Wilke Some volcanoes perform a rather subtle trick: blowing rings of vapor that waft ...

Researchers discovered that continents don’t just split at the surface—they also peel from below, feeding volcanic activity in the oceans. Simulations reveal that slow mantle waves strip continental ...

Some volcanoes, such as the Cascade volcanoes up in Washington and Oregon, are of the type called a stratovolcano. These steep volcanoes sometimes erupt explosively and other times have calmer lava ...

Earth scientists have discovered how continents are slowly peeled from beneath, fueling volcanic activity in an unexpected ...

Crucially, to make rings, a volcanic vent must be fairly circular, and the sides of the vents have to be the same height. If the vent is too irregularly shaped or broken up, the ring may be severely ...

An undersea volcano erupted off Japan three weeks ago, providing a rare view of the birth of a tiny new island, but experts say it may not last very long. The unnamed undersea volcano, located about ...

A new island recently appeared in the south Pacific Ocean, but it has no name just yet, according to NPR. The new land was seen "pok[ing] out" after an underwater volcano erupted earlier in the month.
