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 ...

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 ...

Researchers traced tremor signals deep inside Tanzania’s Oldoinyo Lengai volcano, pinpointing their 3D locations for the ...

Some volcanoes, called stratovolcanoes, sometimes erupt explosively and other times have calmer lava flows that just spill out on the surface. A shield volcano is very different and is built almost ...

Scientists have long wondered how volcanoes formed in central Anatolia despite being far from tectonic plate borders—now they've found evidence of a hot plume of magma flowing from East Africa. Riders ...

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 ...
