Volcanoes

Researchers discovered that an underwater volcano nearly a mile beneath the surface off the Pacific coast of Canada is spouting hot fluid, providing a little-known species of skate with an ideal nursery.

An eruption opened a 1.7-mile-long fissure in the ground on Monday (June 10), with lava still spewing and flowing south towards the site of the region's last volcanic eruption.

The volcano beneath Italy erupted 40,000 years ago and had catastrophic impact on Earth's climate — around the same time that the Neanderthals began their slow march to extinction.

In 1538, the ground beneath the Campi Flegrei supervolcano rose by six stories. Then it burst.

Scientists have worked out the consistency of the magma under the Yellowstone caldera using seismic waves — and the reservoir is filled with "mush" that doesn't pose an imminent eruption threat.

Hawaii's Kilauea volcano started erupting last week. Wind around the eruption site could carry volcanic smog and thin glass shards across the Big Island.

From Krakatoa to the Tonga blast, here are some of the biggest volcanic eruptions in recorded history.

Italy's Campi Flegrei is showing some troubling early warning signs, but scientists caution that its eruption is far from certain.

The last caldera-forming eruption at Yellowstone "was much more complex than previously thought," according to the annual report about activity at the supervolcano.

The Borealis Mud Volcano is only the second found in Norwegian waters and releases a continuous stream of methane-rich, muddy liquid from deep below Earth's crust.
