Underwater volcano's fiery eruption captured in detail by seafloor observatory
Underwater volcano fiery eruption captured seafloor observatory
2016/12/27
A sensor array off the Pacific Northwest coast has captured the cracking, bulging and shaking from the eruption of Axial Seamount, a nearly mile-high undersea volcano, in more detail than ever before....
Virginia Tech researchers explore gigantic volcanic eruptions that caused worldwide mass extinctions
Virginia Tech researchers volcanic eruptions caused worldwide mass extinctions

A paper published in Nature Communications by Virginia Tech researchers confirms a major feature in the formation of large igneous provinces — massive worldwide volcanic eruptions that created in...
Enormous dome in central Andes driven by huge magma body beneath it
Enormous dome central Andes driven huge magma body beneath
2016/11/4
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...
In 2010, Iceland's Eyjafjallajokull volcano -- its crater covered by glacier ice -- erupted, spewing clouds of ash that led to delays in flights to and from Europe. Now Katla, another Iceland volcano,...

The cataclysmic 1991 eruption of Mount Pinatubo in the Philippines masked the full impact of greenhouse gases on accelerating sea level rise, according to a new study."These scientists have disentangl...
Super-eruptions may give only a year’s warning before they blow
Super-eruptions only a year’s warning
2016/8/1
Super-eruptions–volcanic events large enough to devastate the entire planet – give only about a year’s warning before they blow.That is the conclusion of a new microscopic analysis of quartz crystals ...
When dormant volcanoes are about to erupt, they show some predictive characteristics—seismic activity beneath the volcano starts to increase, gas escapes through the vent, or the surrounding ground st...

Repeatedly throughout Earth’s history, giant pools of magma greater than 100 cubic miles in volume have formed a few miles below the surface.They are the sources of super-eruptions – gigantic volcanic...
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...

This is the 11th part in a series on NSF's geosciences risk and resilience interest area. Please see parts one, two, three,four, five, six, seven, eight, nine...
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...
