Deep magma matters in volcanic eruption cycle
Although the Soufriere Hills volcano on Montserrat exhibits cycles of eruption and quiet, an international team of researchers found that magma is continuously supplied from deep in the crust but that a valve acts below a shallower magma chamber, releasing lava to the surface periodically. view more (2008-10-10)
Scientists link volcanic eruptions that formed North Atlantic Ocean to ancient global warming
Scientists examining a spike in worldwide ocean temperatures 55 million years ago have linked it to massive volcanic eruptions that pushed Greenland and northwest Europe apart to create the North Atlantic Ocean. view more (2007-04-27)
Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere. view more (2006-02-24)
Mars Express reveals the Red Planet's volcanic past
A new analysis of impact cratering data from Mars reveals that the planet has undergone a series of global volcanic upheavals. These violent episodes spewed lava and water onto the surface, sculpting the landscape that ESA's Mars Express looks down on today. view more (2008-03-17)
Volcanoes cool the tropics, say researchers
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics-but suggest that such effects may have been masked in the 20th century by rising global temperatures. view more (2009-01-06)
Mega Eruption of Yellowstone's Southern Twin
North America isn't the only continent that's experienced super-colossal volcanic eruptions in the recent geologic past. view more (2006-03-29)
When will Mount St Helens erupt?
Research reported in Science today (14 October 2004) shows that rocks erupted from the Mount St Helens volcano in 1980 preserve a remarkable record of the goings-on beneath the volcano in the period prior to its eruption. view more (2004-10-12)
Geologists discover signs of volcanoes blowing their tops in the deep ocean
A research team led by the Woods Hole Oceanographic Institution (WHOI) has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. view more (2008-06-26)
Tracking a hot spot
Using a state-of-the-art satellite imagery technique, researchers are able to more precisely predict volcanic activity, bringing them steps closer to understanding where an eruption may occur. view more (2007-05-18)
Historic volcanic eruption shrunk the mighty Nile River
Volcanic eruptions in high latitudes can greatly alter climate and distant river flows, including the Nile, according to a recent study funded in part by NASA. view more (2006-11-22)
Researchers to study rebirth of an island after volcanic eruption
When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick. view more (2009-08-07)
UB Geologists to Help Communicate the Dangers of Colombian Volcano
During the past decade, residents of Pasto, Colombia, and neighboring villages near Galeras, Colombia's most dangerous volcano, have been threatened with evacuation, but compliance varies. view more (2009-07-01)
Yellowstone's Ancient Supervolcano: Only Lukewarm?
The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found. view more (2008-08-28)
Venus Express reboots the search for active volcanoes on Venus
ESA's Venus Express has measured a highly variable quantity of the volcanic gas sulphur dioxide in the atmosphere of Venus. Scientists must now decide whether this is evidence for active volcanoes on Venus, or linked to a hitherto unknown mechanism affecting the upper atmosphere. view more (2008-04-07)
New map hints at Venus's wet, volcanic past
Venus Express has charted the first map of Venus's southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with both, a plate tectonics system and an ocean of water. view more (2009-07-14)
Geologists witness unique volcanic mudflow in action in New Zealand
Volcanologist Sarah Fagents from the School of Ocean and Earth Science and Technology (SOEST) at the University of Hawaii at Manoa had an amazing opportunity to study volcanic hazards first hand, when a volcanic mudflow broke through the banks of a volcanic lake at Mount Ruapehu in New Zealand. view more (2007-07-16)
Scientists measure the rate of ascent of volcanic magma
Plinian volcanic eruptions are notoriously destructive. These very powerful eruptions often occur after long periods of quiescence and are preceded by relatively short periods of seismic restiveness. view more (2009-10-09)
Volcanoes, asteroids and mass extinctions
Neither massive volcanic eruptions nor extraterrestrial impacts are sufficiently powerful on their own to cause mass extinctions of life on Earth, research by University of Leicester geologists suggests. Instead, both events coincidentally occurring together may be required to cause the worst mass extinctions. In the last 300 million years, life... view more... (2004-05-17)
Blast From the Past: the `Minoan` eruption of Santorini (Thera) @ the London `Catastrophes` conference
The mid-second millennium `Minoan` eruption of Santorini (Thera) was one of the largest volcanic eruptions known to have occurred during the Holocene. It is also one of the most controversial, with the eruption being blamed for many far-reaching environmental and societal events, most notably the end of the Minoan civilisation on Crete. view more (2002-08-17)
New research puts 'killer La Palma tsunami' at distant future
The volcanic island of La Palma in the Canaries is much more stable than is generally assumed, Dutch scientists working at the TU Delft have found. view more (2006-09-21)
