New research led by a University of Calgary geophysicist provides strong evidence against continent formation above a hot mantle plume, similar to an environment that presently exists beneath the Hawaiian Islands.
The type of particles which are most harmful to jet engines were the first to fall out of the Eyjafjallajökull ash plume following the volcano's eruption in 2010, delegates at the Goldschmidt conference will be told today.
A volcano off New Zealand sent a plume of steam two kilometres (1.24 miles) into the air Tuesday, although volcanologists described the eruption as small and said it was over in minutes.
A new online tool for predicting the amount of ash pumped into the atmosphere during a volcanic eruption has been made openly available to scientists around the world.
A remote Alaska volcano is again oozing lava into its ice-filled caldera, but there's no cause for alarm for nearby residents.
(Phys.org) —Two of Alaska's most active volcanoes—Pavlof and Cleveland—are currently erupting. At the time of this post, their activity continues at low levels, but energetic explosions could occur without warning.
(Phys.org) —Semi-precious minerals found in a bucket of sand from an island nation have cracked open a clue to the drifting movements and break-up of ancient Earth's massive continental plates.
On May 3, 2013, the NOAA GOES infrared and visible imagery were combined to create an animation that showed the plume of smoke from the fire. The smoke plume is seen blowing west and out over the eastern Pacific Ocean. The ...
(Phys.org) —An international team of researchers, including an entomologist at the University of California, Riverside, has an explanation for why we see so many hybrid moths in nature. The team closely examined the behavior ...
A debate among scientists about the geologic formation of the supervolcano encompassing the region around Yellowstone National Park has taken a major step forward, thanks to new evidence provided by a team of international ...
