Scientists disagree about the timing of the Taupō volcanic eruption — one of the largest on Earth in the past 5,000 years — but shards of glass discovered in Antarctic ice could settle this debate.

The magma that erupts from basaltic volcanoes in the middle of tectonic plates originates from within Earth's mantle — rather than from the outer crust — and is propelled upward by CO2, not water.

As well as tornadoes, loud bangs sounding across the Reykjanes Peninsula indicate that pockets of methane within the lava are exploding.

Dozens of circular loops made from smoke and volcanic gas are rising from a peculiar vent on Mount Etna every day.

Drone footage captures Iceland's "baby volcano" throwing a hissy fit, spewing molten lava into the sky.

Massive eruptions 719 million years ago in what is now Canada may have sucked enough CO2 from the atmosphere to freeze Earth over 2 million years later.

Iceland's newest volcano, located in the Reykjanes peninsula, began erupting in early July, 2023. Now it's throwing "spatter bombs'" of molten lava.

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.
