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.

Media Tip Sheet: URI Research to Be Presented at International Earth Science Meeting, Dec. 15-19

Research on underwater volcanoes, Great Lakes pollution, subseafloor life and much more will be among the 40 projects that will be presented by scientists from the University of Rhode Island’s Graduate School of Oceanography at the American Geophysical Union’s fall meeting in San Francisco from Dec. 15 to 19.

UW Team Explores Large, Restless Volcanic Field in Chile

For seven years, an area larger than the city of Madison has been rising by 10 inches per year. That rapid rise provides a major scientific opportunity: to explore a mega-volcano before it erupts. That effort, and the hazard posed by the restless magma reservoir beneath Laguna del Maule, are described in a major research article in the December issue of GSA Today.

How Water Could Have Flowed on Mars

mars_volcano_Weizmann.jpg

The surface of Mars clearly shows what looks like evidence of flowing water: riverbeds, deltas, and the like. But these signs have been a puzzle – until now. The Weizmann Institute’s Dr. Itay Halevy and Brown University’s Dr. James Head III have identified a possible source: violent eruptions from massive volcanoes that periodically melted Mars’ ice.

New View of Mount Rainier's Volcanic Plumbing

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier’s deep volcanic plumbing and partly molten rock that will erupt again someday.

Scientists Ready to Study Magma Formation Beneath Mount St. Helens

University and government scientists are embarking on a collaborative research expedition to improve volcanic eruption forecasting by learning more about how a deep-underground feeder system creates and supplies magma to Mount St. Helens.
