Oceanic crust breakthrough: Solving a magma mystery
Oceanic crust covers two-thirds of the Earth's solid surface, but scientists still don't entirely understand the process by which it is made. View More (2012-11-30)
Deep magmatic plumbing of mid-ocean ridges revealed
Some of the highest quality images ever taken of the Earth's lower crust reveal that the upper and lower crust form in two distinctly different ways. View More (2005-08-25)
Magma power for geothermal energy?
When a team of scientists drilling near an Icelandic volcano hit magma in 2009, they had to abandon their planned experiments on geothermal energy. View More (2011-02-18)
When will Mount St Helens erupt?
Research reported in Science today (14 October 2004) shows that rocks erupted from the Mount St Helens volcano in 1980 preserve a remarkable record of the goings-on beneath the volcano in the period prior to its eruption. View More (2004-10-12)
Scientists identify trigger for explosive volcanic eruptions
Scientists from the University of Southampton have identified a repeating trigger for the largest explosive volcanic eruptions on Earth. View More (2012-10-15)
Volcanic plumbing exposed
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to predicting large eruptions. View More (2012-03-30)
Deep magma matters in volcanic eruption cycle
Although the Soufriere Hills volcano on Montserrat exhibits cycles of eruption and quiet, an international team of researchers found that magma is continuously supplied from deep in the crust but that a valve acts below a shallower magma chamber, releasing lava to the surface periodically.

Sulphur proves important in the formation of gold mines
Collaborating with an international research team, an economic geologist from The University of Western Ontario has discovered how gold-rich magma is produced, unveiling an all-important step in the formation of gold mines. View More (2011-01-07)
Pre-eruption earthquakes offer clues to volcano forecasters
Like an angry dog, a volcano growls before it bites, shaking the ground and getting "noisy" before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to Emily Brodsky, an associate professor of Earth and planetary sciences at the University of California, Santa Cruz.

Volcanic plumbing provides clues on eruptions and earthquakes
Two new studies into the "plumbing systems" that lie under volcanoes could bring scientists closer to understanding plate ruptures and predicting eruptions-both of which are important steps for protecting the public from earthquake and volcanic hazards. View More (2012-04-13)
Tracking a hot spot
Using a state-of-the-art satellite imagery technique, researchers are able to more precisely predict volcanic activity, bringing them steps closer to understanding where an eruption may occur. View More (2007-05-18)
Months of geologic unrest signaled reawakening of Icelandic volcano
Months of volcanic restlessness preceded the eruptions this spring of Icelandic volcano Eyjafjallajökull, providing insight into what roused it from its centuries of slumber. View More (2010-11-19)

10 years of Soufriere Hills Volcano research published
The Soufriere Hills Volcano on Montserrat erupted in 1995, and an international team of researchers has studied this volcano from land and sea since then to understand the workings of andesite volcanos more completely. View More (2010-11-19)
A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. View More (2009-11-13)
'Magma P.I.' unearths clues to how crust was sculpted
About a decade ago, Johns Hopkins University geologist Bruce Marsh challenged the century-old concept that the Earth's outer layer formed when crystal-free molten rock called magma oozed to the surface from giant subterranean chambers hidden beneath volcanoes. View More (2007-12-04)
UBC study may solve age-old mystery of missing chemicals from Earth's mantle
Observations about the early formation of Earth may answer an age-old question about why the planet's mantle is missing some of the matter that should be present, according to UBC geophysicist John Hernlund. View More (2007-12-06)
A new type of volcanic eruption
Scientists based in the UK and New Zealand have described a "new" type of volcanic eruption. View More (2013-01-22)
Supervolcanoes: Not a threat for 2012
The geological record holds clues that throughout Earth's 4.5-billion-year lifetime massive supervolcanoes, far larger than Mount St. Helens or Mount Pinatubo, have erupted. However, despite the claims of those who fear 2012, there's no evidence that such a supereruption is imminent. View More (2011-11-16)
Evidence from Hawaiian volcanoes shows that Earth recycles its crust
A geologist at Rutgers, The State University of New Jersey, has come up with evidence our planet practices recycling on a grand scale. View More (2006-11-30)
