New ‘Geospeedometer’ Confirms Super-Eruptions Have Short Fuses

Vanderbilt University

A new "geospeedometer" that can measure the amount of time between the formation of an explosive magma melt and an eruption confirms that the process took less than 500 years in several ancient super-eruptions.

Quantifying the Impact of Volcanic Eruptions on Climate

Université de Genève (University of Geneva)

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.

Scientists See Deeper Yellowstone Magma

University of Utah

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

University of Utah

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.
