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 ...

Doubt over 'volcanic winter' after Toba super-eruption

(Phys.org) —New research from Oxford University casts doubt on the theory that the Mount Toba super-eruption, which took place at the Indonesian island of Sumatra 75,000 years ago, could have plunged the Earth into a volcanic ...

Global extinction: Gradual doom is just as bad as abrupt

A painstakingly detailed investigation shows that mass extinctions need not be sudden events. The deadliest mass extinction of all took a long time to kill 90 percent of Earth's marine life, and it killed in stages, according ...

Supervolcanoes: A key to America's electric future?

Most of the lithium used to make the lithium-ion batteries that power modern electronics comes from Australia and Chile. But Stanford scientists say there are large deposits in sources right here in America: supervolcanoes.

Venus' ancient layered, folded rocks point to volcanic origin

An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic ...

Researchers examine how ore deposits are formed

(Phys.org)—New computer simulations by geologists from ETH Zurich demonstrate how large copper and gold deposits are formed. The enrichment process of these metals follows physical principles that are similar to the extraction ...

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 ...
