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 ...
Possible trigger for volcanic 'super-eruptions' found
The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers ...
Second bid to launch NASA's Moon-bound spacecraft
NASA will try again Friday to launch a $500 million pair of unmanned spacecraft that will use gravity tools to map the Moon's inner core for the first time, after high winds delayed a first attempt.
Man in the moon looking younger
Earth's Moon could be younger than previously thought, according to new research from a team that includes Carnegie's Richard Carlson and former-Carnegie fellow Maud Boyet. Their work will be published online ...
Iceland's Hekla volcano shows signs of activity
(AP) -- Scientists are monitoring unusual underground activity that could signal an eruption at the Hekla volcano in southern Iceland.
Parts of moon interior contains as much water as Earth's upper mantle
Parts of the moon's interior contains as much water as the upper mantle of the Earth - 100 times more of the precious liquid than measured before research from Case Western Reserve University, Carnegie ...
Scientists move closer to predicting volcano hazard
UK and Russian scientists say they are a step closer to predicting how dangerous a volcano is after developing a method that lets them figure out how individual volcanoes are 'plumbed'.
Galileo spacecraft reveals magma 'ocean' beneath surface of Jupiter's moon Io
A new analysis of data from NASA's Galileo spacecraft has revealed that beneath the surface of Jupiter's volcanic moon Io is an "ocean" of molten or partially molten magma.
Magma chambers awake sooner than thought
Until now it was thought that once a volcano's magma chamber had cooled down it remained dormant for centuries before it could be remobilized by fresh magma. A theoretical model developed by Alain Burgisser of the Orléans ...
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. But the mishap could point the way to an alternative source of geothermal ...
Geologists get unique and unexpected opportunity to study magma
Geologists drilling an exploratory geothermal well in 2009 in the Krafla volcano in Iceland encountered a problem they were simply unprepared for: magma (molten rock or lava underground) which flowed unexpectedly ...
Hot stuff: Magma at shallow depth under Hawaii
Ohio State University researchers have found a new way to gauge the depth of the magma chamber that forms the Hawaiian Island volcanic chain, and determined that the magma lies much closer to the surface than previously thought.
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 centuries of slumber.
Novel ocean-crust mechanism could affect world's carbon budget
The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet's metabolism, including the cycle ...
