The mudslides that follow wildfires in Southern California can be deadly -- and difficult to predict. New National Science Foundation-funded research will help officials identify areas prone to these ...
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the impact of an asteroid, the ...
Geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone -- a layer rich in water, crystals and melted rock -- can percolate to the surface...

The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades – and a new study has found that these sites also may exper...
Taking advantage of a rare orbital alignment between two of Jupiter’s moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the most volcanicall...
UMD-led Study Finds Ancient Earth’s Fingerprints in Young Volcanic Rocks
UMD-led Ancient Earth’s Fingerprints Young Volcanic Rocks
2017/4/27
Earth’s mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth’...
Holidaymakers concerned about fresh volcanic eruptions causing flight-disrupting ash clouds might be reassured by a study setting out the first reliable estimates of their frequency.While the Universi...
