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 ...

A new study uncovers how volatile-rich magmas propel diamond-bearing kimberlites from Earth’s depths. If you’ve ever admired a diamond, chances are it originated from a kimberlite. More than 70% of ...

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 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 ...

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 ...

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 ...

The Cumbre Vieja volcano, located on the island of La Palma within the Canary Islands of Spain, has been erupting since September. Scientists from around the world are flying into La Palma so they can ...

An ongoing volcanic eruption has created a tiny island near Iwoto. The new island is about 328 feet (100 meters) in diameter, according to researchers. This is a rare phenomenon, but it may not last ...
