Ask a volcanologist anything you want to know about volcanoes!

Volcanoes! Whether we're talking about Pompeii, why some volcanoes in Indonesia are erupting with blue lava, or the mechanics of supervolcanoes, they're totally fascinating. Today, we have a volcanologist in to answer your questions about volcanoes, eruptions, and their aftereffects. » 2/24/14 9:10am 2/24/14 9:10am

Actually, it was not a surprise when a volcano destroyed Pompeii

With the movie Pompeii exploding into theaters, you'll be exposed to a lot of myths about the volcanic eruption at Mt. Vesuvius that buried a whole Roman town. The biggest myth of all is that the citizens of Pompeii never knew the blast was coming. They did. And many had already evacuated. » 2/21/14 2:31pm 2/21/14 2:31pm

A major step to predicting when supervolcanoes will explode

Scientists have learned that massive caldera volcanoes, like the one stewing beneath Yellowstone, are ruled by geological processes far different than the ones governing conventional volcanoes. These massive reservoirs of magma can explode spontaneously — an important piece of insight that can help us predict a future… » 1/06/14 2:20pm 1/06/14 2:20pm

There's an active volcano deep beneath the Antarctic ice sheet

It's a song of fire and ice — an active volcano that's spewing magma at a depth of more than a half-mile beneath a massive sheet of ice. It's an unprecedented discovery that hints at the possibility for a huge eruption, but with completely unpredictable consequences. » 11/18/13 9:20am 11/18/13 9:20am

A stunning example of nature's resilience

The 1980 eruption of Mount St. Helens is regarded as the deadliest and most destructive volcanic blast in U.S. history. And yet, just thirty-three years later, life has returned to the area in almost equally impressive force, as newly released photographs illustrate. » 10/22/13 2:11pm 10/22/13 2:11pm

One of the solar system’s largest volcanoes is right here on Earth

Move over, Mauna Loa, there’s a volcano on Earth that’s even bigger than you. Scientists have confirmed the existence of a massive underwater volcano that could be the second largest in the solar system — one that even rivals Olympus Mons on Mars. » 9/06/13 8:00am 9/06/13 8:00am

How far would you go to get the perfect shot?

Amateur photographer Kawika Singson routinely ventures out to Hawaii Volcanoes National Park to snap some pics. But this time around, after setting up his equipment on a lava flow, his shoes and tripod caught fire. The photo has since gone viral — but is it real? » 7/17/13 6:34am 7/17/13 6:34am

Man runs on top of an active lava flow, is an idiot

From filmmaker Marc Szeglat comes this video of a "lava art craft worker" scrambling his way up a lava flow on Italy's Mount Etna, one of the most active volcanos on Earth. The flow is literally glowing with heat, which makes this craft worker literally an idiot. » 6/18/13 12:20pm 6/18/13 12:20pm

How to Measure the Explosive Power of Volcanoes

Scientists have scales to measure the strength of natural phenomena like earthquakes and hurricanes. But what about the eruptive power of volcanoes? For that, geologists use the Volcanic Explosivity Index. Here’s how it works. » 4/25/13 9:00am 4/25/13 9:00am

Further evidence that volcanoes can destroy life on Earth

If you think asteroid strikes are scary, I've got some bad news for you. The most deadly events on Earth are caused by . . . Earth. New evidence suggests that underwater volcanoes may have wrecked our planet for thousands of years, and ultimately allowed dinosaurs to rule the world. » 3/21/13 2:31pm 3/21/13 2:31pm
