Mount Etna's strange lava has long perplexed scientists, but new research reveals that the volcano formed in a bizarre way — making it unlike any other known volcano on Earth.

Learn how magma, gas, and water drive eruptions; compare eruption and volcano types, understand warning signs, and follow ...

Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

Volcanoes are grouped into four types: cinder cones, composite volcanoes, shield volcanoes and lava volcanoes. Cinder cones are circular or oval cones made up of small fragments of lava from a single ...

The most recent eruptive pulse of the West Eifel Volcanic Field occurred approximately 25,000 years ago. At that time, a group of volcanic lakes known as the Dauner Maare were formed, among others.

Over millions of years, the Earth’s upper layers have performed a dance that has created mountains, volcanoes, continents, ridges and ocean trenches. Tectonic plates play a key role in this process.
