The asteroid Psyche may have once had vents that spewed molten metal — but only if it is chemically similar to rare, metal-rich meteorites, a new study suggests. The study, which was published online July 31 in the Journal of Geophysical Research: Planets, could explain why the space rock has an unusual metallic cloak. Potato-shaped asteroid Psyche, a member of …

A new study used earthquake waves to peer under the Cascade Range, revealing persistent pockets of magma beneath several quiet peaks. These pockets are not full lakes of magma, but zones of partial melt where hot rock contains some liquid. Using distant, or teleseismic, earthquakes and a method called receiver functions, researchers mapped low seismic velocity zones about 3 to …

How did humans become human? Understanding when, where and in what environmental conditions our early ancestors lived is central to solving the puzzle of human evolution. Unfortunately, pinning down a timeline of early human evolution has long been difficult – but ancient volcanic eruptions in East Africa may hold the key. Our new study, published in Proceedings of National Academy …

This 8,200-foot giant in Alaska has just provided the key to the mystery behind the eruption of the most sneaky of volcanoes: the stealth type.  evidencenetwork.ca Source link

A groundbreaking discovery in southern China has revealed a 400-mile-long chain of extinct volcanoes buried deep below the Sichuan Basin, a region historically part of the Yangtze Block. The findings, outlined in a recent study published in the Journal of Geophysical Research: Solid Earth, shed light on the ancient volcanic activity that took place during the early breakup of the supercontinent …

Researchers have discovered a 400-mile-long chain of extinct, fossilized volcanoes buried deep below South China. The volcanoes formed when two tectonic plates collided during the breakup of the supercontinent Rodinia hundreds of millions of years ago, the scientists reported in a new study. The ancient volcanoes extend the region of past volcanism in this area by several hundred miles and …

Scientists are warning that glaciers melting due to global warming could trigger explosive — and potentially deadly — volcanic eruptions around the world. As detailed in a new study presented at the Goldschmidt international geochemistry conference this week and due to be peer-reviewed later this year, researchers from the University of Wisconsin-Madison analyzed six volcanoes in southern Chile to study …

The effects of climate change could awaken hundreds of volcanoes worldwide – which in turn could worsen the effects of climate change. According to recent models predicting changes in the magma beneath Patagonia’s glaciers, the retreat of ice has the power to shake subglacial volcanoes out of their slumber. The world isn’t at imminent risk of volcanic bombardment, but the …
