Simulating Path of 'Magma Mush' Inside an Active Volcano

The first simulation of the individual crystals in volcanic mush, a mix of liquid magma and solid crystals, shows the mixing to help understand pressure buildup deep inside a volcano.

To combat complacency and improve disaster preparedness, a University at Buffalo researcher is heading a new project focusing on two locations: Kīlauea in the Hawaiian Islands, and the Long Valley caldera and volcanic field in eastern central California.

Quantifying the Impact of Volcanic Eruptions on Climate

Sarychev_2009.png

Large volcanic eruptions inject considerable amounts of sulphur in the stratosphere which, once converted into aerosols, block sun rays and tend to cool the surface of the Earth down for several years. An international team of researchers has just developed a method, published in Nature Geoscience, to accurately measure and simulate the induced drop in temperature.

Earthquake Not to Blame for Indonesian Mud Volcano

New research led by the University of Adelaide hopes to close the debate on whether a major mud volcano disaster in Indonesia was triggered by an earthquake or had man-made origins.

Scientists See Deeper Yellowstone Magma

University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times.

A Stiff New Layer in Earth's Mantle

By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain a mystery: why slabs of Earth’s sinking tectonic plates sometimes stall and thicken 930 miles underground.

URI Grad Student Investigates Unexplored Underwater Volcano Off Solomon Islands

URI doctoral student Brennan Phillips is on the hunt for underwater volcanoes so he can collect data on the plumes of hot fluids and chemical compounds emanating from hydrothermal vents in and around the craters. His latest adventure took him to the unexplored Kavachi volcano off the Solomon Islands.
