First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences. The volcano on the West Antarctic Ice Sheet erupted 2,000 years ago and remains active. Using airborne ice-sounding radar, scientists from British Antarctic Survey discovered a layer of ash produced by a (2008-01-20)

Another clue for fast motion of the Hawaiian hotspot
Recent studies have suggested that the Hawaiian hotspot moved relatively quickly southward in the period from 60 to about 50 million years ago. This hypothesis is supported by a new study of Kevin Konrad and colleagues. They have evaluated new rock dating of the Rurutu volcanic chain and added data from the Hawaiian-Emperor chain and the Louisville chain. It shows that the Hawaiian-Emperor hotspot displays strong motion between 60 and 48 million years ago. (2018-02-27)

Novel hypothesis goes underground to predict future of Greenland ice sheet

Giant lava dome confirmed in Japan's Kikai Caldera
Researchers have confirmed that a giant lava dome was created in the Kikai Caldera, south of Japan's main islands after the caldera-forming supereruption 7,300 years ago. The dome is in the world's largest class of post-caldera volcano, with a volume of over 32 cubic kilometers. It is possible that currently a giant magma buildup may exist under the Kikai Caldera.

This new knowledge will help us understand how tectonic plates can break to form new boundaries. (2017-09-13)

Did volcanoes kill the dinosaurs? New evidence points to 'maybe.'
Princeton geoscientists Blair Schoene and Gerta Keller led an international team of researchers who have assembled the first high-resolution timeline for the massive eruptions in India's Deccan Traps, determining that the largest eruption pulse occurred less than 100,000 years before the mass extinction that killed the (non-avian) dinosaurs. (2019-02-22)

Thermal history of magma may help scientists hone in on volcanic eruption forecasts
A new study analyzed crystals of the mineral zircon -- zirconium silicate -- in magma from an eruption in the Taupo Volcanic Zone in New Zealand about 700 years ago to determine the magma's history. This may begin to help scientists recognize when a volcano is heading toward an eruptive phase. (2017-06-15)

Volcanoes and glaciers combine as powerful methane producers
Large amounts of the potent greenhouse gas methane are being released from an Icelandic glacier, scientists have discovered. A study of Sólheimajökull glacier, which flows from the active, ice-covered volcano Katla, shows that up to 41 tonnes of methane is being released through meltwaters every day during the summer months. (2018-11-20)

Mars' oceans formed early, possibly aided by massive volcanic eruptions
A new theory about how oceans and volcanoes interacted during the early history of Mars supports the idea that liquid water was once abundant and may still exist underground. UC Berkeley geophysicists propose that the oceans originated several hundred million years earlier than thought, as the volcanic province Tharsis formed, and that greenhouse gases enabled the oceans. The theory predicts smaller oceans, more in line with estimates of water underground and at the poles today. (2018-03-19)

Breathing? Thank volcanoes, tectonics and bacteria
A Rice University study in Nature Geoscience suggests Earth's first burst of oxygen was added by a spate of volcanic eruptions brought about by tectonics. In addition to explaining the appearance of significant concentrations of oxygen in the Great Oxidation Event (GOE) 2.5 billion years ago, the theory also accounts for the Lomagundi Event, a puzzling shift in the ratio of carbon isotopes in carbonate minerals that followed the GOE.

Discovered: world's largest tsunami debris
A line of massive boulders on the western shore of Tonga may be evidence of the most powerful volcano-triggered tsunami found to date.
