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, 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 ...

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 ...

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 ...

Pulvirenti’s model explains why smoke rings aren’t seen at every volcano all the time, since the rings require such precise conditions to form. Even when these conditions are met, however, smoke rings ...

Unusual molten rock formations, nicknamed lava eggs, have appeared near an active volcano in Iceland. Some were recently spotted by a geologist, who explained to Reuters how the egg-shaped lobes ...
