Although volcanic eruptions are often quite hazardous, scientists have been unable to pinpoint the processes leading up to major eruptions – and one important limitation has been a lack of knowledge a...
Volcanologists are gaining a new understanding of what’s going on inside the magma reservoir that lies below an active volcano, and they’re finding a colder, more solid place than previously thought, ...

A new analysis of the topography of the central Andes shows the uplifting of the Earth's second highest continental plateau was driven in part by a huge zone of melted rock in the crust, known as a ma...
Months of warning signs from Mauna Loa, on Hawaii’s Big Island, prompted the U.S. Geological Survey to recently start releasing weekly updates on activity at the world’s largest active volca...
Yellowstone magma discovery
Yellowstone magma
2015/4/30
A team of University of Utah seismologists has discovered a reservoir of hot, partly molten rock hidden 12 to 28 miles beneath Yellowstone's supervolcano--enough to fill the 1000 cubic-mile-Grand Cany...
It was a bit like making a CT scan of a patient’s head and finding he had very little brain or making a PET scan of a dead fish and seeing hot spots of oxygen consumption. Scientists making seismic im...
amounts of erupting lava are connected to the destruction of supercontinents and dramatic changes in climate and ecosystems.
New research from UC Davis and Aarhus University in Denmark shows that hig...
New research from UC Davis and Aarhus University in Denmark shows that high mantle temperatures miles beneath the Earth’s surface are essential for generating such large amounts of magma. In fact, the...
