What's Up with Madagascar?

Washington University in St. Louis

The island of Madagascar off the coast of Africa was largely unexplored seismically until recently. The first broadband seismic images of the island help solve a longstanding mystery: why are there volcanoes far from any tectonic boundary?

Researchers Explore Gigantic Volcanic Eruptions That Caused Worldwide Mass Extinctions

Virginia Tech

A paper in Nature Communications confirms a major feature in the formation of large igneous provinces — massive worldwide volcanic eruptions that created incredibly high volumes of lava and triggered environmental catastrophes and mass extinctions from 170 to 90 million years ago.

Ceres: The Tiny World Where Volcanoes Erupt Ice

Arizona State University (ASU)

Ahuna Mons is a volcano that rises 13,000 feet high and spreads 11 miles wide at its base. This would be impressive for a volcano on Earth. But Ahuna Mons stands on Ceres, a dwarf planet less than 600 miles wide that orbits the Sun between Mars and Jupiter. Even stranger, Ahuna Mons isn't built from lava the way terrestrial volcanoes are -- it's built from ice.

New Study Upends a Theory of How Earth's Mantle Flows

Earth Institute at Columbia University

A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth's mantle flows beneath the ocean's tectonic plates. The findings, published in the journal Nature, appear to upend a common belief that the strongest deformation in the mantle is controlled by large-scale movement of the plates. Instead, the highest resolution imaging yet reveals smaller-scale processes at work that have more powerful effects.

Geologists Make Their Own Lava to Prep for Explosive Experiments (Video Available)

University at Buffalo

The lava-making operation — one of the largest in the world — will provide a rare, close-up view of the interplay between molten rock and water, an interaction that can enhance the explosive potential of volcanoes.

Scientists Gain Supervolcano Insights From Wyoming Granite

University of Wyoming

Geophysical monitoring of the ground above active supervolcanoes shows that it rises and falls as magma moves beneath the surface of the Earth. Silica-rich magmas like those in the Yellowstone region and along the western margin of North and South America can erupt violently and explosively, throwing vast quantities of ash into the air, followed by slower flows of glassy, viscous magma.
