Yellowstone supereruption would send ash across North America

In the unlikely event of a volcanic supereruption at Yellowstone National Park, the northern Rocky Mountains would be blanketed in meters of ash, and millimeters would be deposited as far away as New York City, Los Angeles ...

How much magma is hiding beneath our feet?

Molten rock (or magma) has a strong influence on our planet and its inhabitants, causing destructive volcanic eruptions and generating some of the giant mineral deposits. Our understanding of these phenomena is, however, ...

New volcanos found in Victoria

Geologists have discovered three previously unrecorded volcanoes in volcanically active southeast Australia.

Understanding the planets through volcanoes

Billions of years ago, volcanoes sent material from inside planetary bodies to the surface. Subsequent impacts have covered those original deposits. Jennifer Whitten, who receives her Ph.D. in geological sciences this year, ...

Ancient volcanic explosions shed light on Mercury's origins

Mercury was long thought to be lacking volatile compounds that cause explosive volcanism. That view started to change when the MESSENGER spacecraft returned pictures of pyroclastic deposits—the telltale signature of volcanic ...

Explosive volcanoes light up Mercury's deep past

Mercury has long been a mystery to scientists. Until recently, knowledge of the planet was limited to the grey, patchy landscape revealed by the Mariner 10 probe, NASA's first mission to Mercury in the mid-1970s.

Simulating flow from volcanoes and oil spills

Some time around 37,000 BCE a massive volcano erupted in the Campanian region of Italy, blanketing much of Europe with ash, stunting plant growth and possibly dooming the Neanderthals. While our prehistoric relatives had ...
