Volcanoes like Kīlauea and Mauna Loa don't erupt like we thought they did, scientists discover
Volcanoes that sit within Earth's tectonic plates don't erupt how scientists thought they did. It turns out, magma within these volcanoes is propelled up and out of the ground by carbon dioxide — not by water, as was previously thought, a new study finds. This magma also shoots up from...
Massive New Zealand eruption 1,800 years ago flung volcanic glass 3,000 miles to Antarctica

Massive New Zealand eruption 1,800 years ago flung volcanic glass 3,000 miles to Antarctica
When New Zealand's Taupō volcano erupted 1,800 years ago, its immense blast flung shards of glass all the way to Antarctica. Now, scientists have unearthed some of this ancient volcanic debris — which could help pinpoint the exact year this huge eruption took place. Fallout from the Taupō eruption —...

California's supervolcano has a massive lid that causes swarms of earthquakes — and that's a good thing, scientists say
A shuddering supervolcano in California is simmering down, not ramping up, thanks to a giant lid that is covering its magma reservoir, new research finds. The Long Valley Caldera in the Eastern Sierra Nevada mountains has been unleashing earthquake swarms on a regular basis since 1978, raising concerns that it...
Perilous expedition to uninhabited island in South Atlantic confirms existence of world's 8th lava lake

Perilous expedition to uninhabited island in South Atlantic confirms existence of world's 8th lava lake
In 2001, NASA satellites scanning an uninhabited island near Antarctica in the South Atlantic Ocean detected a thermal anomaly that left scientists reeling. Deep inside an unexplored volcano, they detected the signature of a bubbling lake of molten rock. Only seven such lava lakes were known worldwide. With nothing but...

Astronaut captures image of a glowering 'skull' lurking in a giant volcanic pit in the Sahara
To celebrate the spooky season, NASA has released a bone-chilling photo of a creepy skull that appears to glower up toward space from the heart of an enormous volcanic pit in Chad. The uncanny image was captured Feb. 12 by an unnamed astronaut aboard the International Space Station (ISS), as...

Underwater volcanic eruption gives birth to new island in the Pacific
An underwater volcanic eruption on Oct. 30 has birthed a new island in the Pacific after the explosion flung huge chunks of rock into a pile off the coast of Japan's Iwo Jima island. An aircraft belonging to the Japanese newspaper Mainichi Shimbun spotted the first signs of an eruption...

New island that emerged from the ocean off Japan is now visible from space
A newborn island that recently emerged from the Pacific Ocean after an underwater volcanic eruption is now visible from space, images from the European Space Agency (ESA) reveal. The satellite images show the new landmass sitting around 0.6 mile (1 kilometer) off the coast off Japan's Iwo Jima island. The...

Iceland volcano: Eruption feared as 10-mile-long 'magma tunnel' forms beneath town
A volcanic eruption in or near the town of Grindavík in Iceland is now likely imminent, with experts warning that magma is moving closer to the surface. An eruption could be possible on a timescale of just days, according to a translated statement from the Icelandic Met Office (IMO). Grindavík...

Russia's tallest volcano spews out 1,000-mile-long river of smoke after giant eruption, satellite images reveal
Eurasia's tallest volcano has violently erupted, throwing a 1,000-mile-long (1,600 kilometers) cloud of dust and ash into the air, new NASA satellite images show. Klyuchevskoy, sometimes referred to as Klyuchevskaya Sopka, is an active stratovolcano in Russia's Kamchatka Peninsula, which is home to more than 300 other volcanos. Klyuchevskoy's peak...

'Time's finally up': Impending Iceland eruption is part of centuries-long volcanic pulse
Iceland's potentially imminent eruption in the Reykjanes Peninsula is part of a 1,000-year cycle of volcanic activity that will likely cause eruptions for centuries, scientists say. Time's finally up, Edward W. Marshall, a researcher at the University of Iceland's Nordic Volcanological Center, told Live Science in an email. We can...
Supervolcano 'megabeds' discovered at bottom of sea point to catastrophic events in Europe every 10,000 to 15,000 years

Supervolcano 'megabeds' discovered at bottom of sea point to catastrophic events in Europe every 10,000 to 15,000 years
Huge megabeds from ancient supervolcano eruptions are hiding at the bottom of the Mediterranean Sea, researchers have found. Their discovery points to a cycle of catastrophic events that appear to hit the region every 10,000 to 15,000 years. Megabeds are huge submarine deposits that form in marine basins as a...

Why is Iceland so volcanically active? A geologist explains
Thousands of earthquakes in recent weeks have shaken the Icelandic fishing town of Grindavík, about 30 miles (50 kilometers) southwest of the capital Reykjavik. They have triggered evacuations and warnings that a volcanic eruption may be imminent. While the idea of magma rising was no doubt scary for tourists visiting...

What will happen if the Iceland volcano finally erupts?
To keep up with the latest developments about the impending eruption, check out our live updates page. Officials in Iceland are preparing for an imminent volcanic eruption from a submerged tunnel of magma, which could unleash superhot lava flows on nearby towns, a vital power plant and an iconic tourist...

Iceland volcano could burst like a 'fizzy drink,' with lava reaching Blue Lagoon resort in days
The risk of a volcanic eruption in Iceland is not diminishing, and — if a fissure does open — lava could reach the Blue Lagoon resort and the Svartsengi geothermal power plant in just days, an expert says. The magma in the 9.3-mile-long (15 kilometers) magma dike, a near-vertical underground...

'It may take more time': Risk of eruption from Iceland volcano still high, with ground 'continuing to swell'
The risk of a volcanic eruption on Iceland's Reykjanes Peninsula is still very high, with ground deformation and earthquakes continuing along the magma dike — a near-vertical underground tunnel running from a magma chamber towards Earth's surface. The 9.3-mile (15 kilometers) magma dike is located between Sundhnúk in the northeast...
