Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on.
A team of specialists from four Australian universities, including the University of Western Australia, has established the exact source of a diamond-bearing rock for the first time.
The varying scale and force of certain volcanic eruptions are directly influenced by the distribution of gases within magma inside a volcano's conduit, according to a new study.
Scientists have produced a new map of the Moon's most unusual volcano showing that its explosive eruption spread debris over an area much greater than previously thought.
In late May 2015, the highest volcano in the Galapagos Islands erupted for the first time in 33 years. The explosive eruption at Wolf volcano on Isabela Island sent volcanic gases and ash roughly 15 kilometers (50,000 feet) ...
Joanna Austin (MS '98, PhD '03) does not just go with the flow. She picks it apart and analyzes it. One of the newest faculty members in Caltech's Division of Engineering and Applied Science is a gas dynamicist, Austin studies ...
The sudden eruption of Mount Ontake over the weekend, which is believed to have killed at least 31 people, was a reminder of Japan's vulnerability to its many active volcanoes.
Extensive, explosive volcanic eruptions may disrupt a crucial aspect of the global nitrogen cycle, say researchers who have investigated ash deposits on the ocean floor.
A new survey suggests that the chamber of molten rock beneath Santorini's volcano expanded 10-20 million cubic metres – up to 15 times the size of London's Olympic Stadium – between January 2011 and April 2012.
Reservoirs of silica-rich magma – the kind that causes the most explosive volcanic eruptions – can persist in Earth's upper crust for hundreds of thousands of years without triggering an eruption, according to new University ...
