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)
British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)
Real-Time Seismic Monitoring Station Installed Atop Active Underwater Volcano
This week, researchers will begin direct monitoring of the rumblings of a submarine volcano in the southeastern Caribbean Sea. view more (2007-05-11)
CU-Boulder team discovers first ancient manioc fields in Americas
A University of Colorado at Boulder team excavating an ancient Maya village in El Salvador buried by a volcanic eruption 1,400 years ago has discovered an ancient field of manioc, the first evidence for cultivation of the calorie-rich tuber in the New World. view more (2007-08-21)
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)
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)
Earthquake swarms not just clustered around volcanoes, geothermal regions
An earthquake swarm - a steady drumbeat of moderate, related seismic events - over hours or days, often can be observed near a volcano such as Mount St. Helens in Washington state or in a geothermal region such as Yellowstone National Park in Wyoming. view more (2006-10-26)
Important role of groundwater springs in shaping Mars
Data and images from Mars Express suggest that several Light Toned Deposits, some of the least understood features on Mars, were formed when large amounts of groundwater burst on to the surface. view more (2008-12-12)
Mars, methane and mysteries
Mars may not be as dormant as scientists once thought. The 2004 discovery of methane means that either there is life on Mars, or that volcanic activity continues to generate heat below the martian surface. view more (2009-08-10)
Scientists obtain rocks moving into seismogenic zone
An international group of scientists aboard the Deep-Sea Drilling Vessel CHIKYU, operated by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) for the Integrated Ocean Drilling Program (IODP), return from a 40-day scientific expedition off the shore of the Kii Peninsula, Japan on Oct. 10, 2009. view more (2009-10-12)
Renewed volcanic activity at the Phlegrean Fields tracked by Envisat
Satellite images acquired by ESA's Envisat satellite have revealed the volcanic region of the Phlegrean Fields, located in southern Italy near the city of Naples, has entered a new uplift phase. view more (2006-08-22)
New Glacier Outburst Flood in Iceland
On July 9th researchers from Keele and Staffordshire Universities and the Icelandic Meteorological Office identified the source and drainage routes of a glacier outburst flood or 'jokulhlaup' which is currently draining from the western margin of Vatnajokull ice cap. The team are currently part of an Earthwatch funded project based at Skaftafell... view more... (2002-07-09)
New definition could further limit habitable zones around distant suns
As astronomers gaze toward nearby planetary systems in search of life, they are focusing their attention on each system's habitable zone, where heat radiated from the star is just right to keep a planet's water in liquid form. view more (2009-06-11)
Preventing obesity in children — research highlights physical activity levels
A British study, involving 5,500 children and published in the latest issue of PLoS Medicine, used accurate methods to measure the 'fat mass' of the children and the amount of physical activity they were taking. view more (2007-03-20)
Monitoring Yellowstone earthquake swarms
The Seismological Society of America (SSA) is an international scientific society devoted to the advancement of seismology and its applications in understanding and mitigating earthquake hazards and in imaging the structure of the earth. view more (2009-04-10)
Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean. view more (2007-04-13)
Up, Up and Away: Studying Volcanoes With Balloon
People do all kinds of crazy things in Hawaii, but flying balloons over a volcano usually isn't one of them. Unless you're Adam Durant, that is. view more (2008-08-15)
EARLY HOMINOIDS MAY HAVE SUFFERED DEATH BY VOLCANO
Geological re-evaluation of deposits in which fossils of the human precursor Proconsul have long been found suggests that they lived in a semi-arid environment close to a then-active volcano (Kisingiri). Moreover the abundant hominoid fossils may represent "death assemblages" - whole populations wiped out simultaneously by "glowing cloud"... view more... (1999-04-28)
Geologist plans volcano safety for Ecuadorians
A geologist at Washington University in St. Louis is doing his part to make sure that the small Latin American country of Ecuador follows the Boy Scout motto: Be prepared. view more (2007-08-22)
Supervolcano eruption -- in Sumatra -- deforested India 73,000 years ago
A new study provides "incontrovertible evidence" that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report. view more (2009-11-24)
