The giant supervolcano that lies under Yellowstone National Park is cooling off in the west but staying hot in the northeast.

Scientists say the enormous Yellowstone supervolcano is stirring in its sleep, with concerns the subterranean monster could blow. The Yellowstone supervolcano is stirring in its sleep. Scientists say ...

The restless lava lake in Nyiragongo's summit crater regularly causes eruptions of gas and smoke laden with tephra. Lava is the word for magma when it erupts onto the Earth's surface. Geologists ...

Below the surface, Earth's rocky rind is ripping apart, and underground chambers of magma are fueling 12 active volcanoes as well as steaming geysers, boiling cauldrons, and a fiery lake of lava.

The Phlegraean Fields is a caldera beneath a gigantic lake of liquid magma. They are more afraid of earthquakes than ...

Kawah Ijen is an active volcano on the island of Java with an extremely acidic crater lake and gas emissions that produce blue flames upon contact with oxygen in Earth's atmosphere.

Lava comes out of ruptures in the Earth's surface, which are connected to pipes, or pathways underground, and a big crater that holds all the magma, like a lake. Underground, magma isn't free ...

It was the interaction of this water with magma that drove a lot of the early explosive behaviour. The dashed line shows the extent of the lake before the onset of Sunday's eruption phase.

heating and melting it to form reservoirs of magma 2½ to 30 miles below the surface. In the past this was often pictured as a single underground lake of lava beneath volcanos, but newer mapping ...
