Conclusive vote on cause of Indonesian mud volcano
A resounding vote of international petroleum geologists from around the globe concluded that the mud volcano was triggered by drilling of a nearby gas exploration well.   view more (2008-10-31)

Scientists Map Soils on an Extinct American Volcano
Union County New Mexico is a landscape of striking diversity. Out of expansive rangelands rise sporadic yet majestic cinder cone volcanoes and mesas preserved by basalt, part of the Raton-Clayton Volcanic Field. Capulin volcano, formed approximately 62,000 years ago, is the youngest volcano in the... view more (2008-10-21)

Lunar Prospecting Robot To Be Field Tested on Hawaii's Mauna Kea
The cool, rocky slopes of Mauna Kea, a dormant volcano that is Hawaii's highest mountain, will serve as a stand-in for the moon as researchers from Carnegie Mellon University's Robotics Institute, NASA and other organizations test a robot designed for lunar prospecting.   view more (2008-10-15)

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)

Discovered: World's Largest Tsunami Debris
A line of massive boulders on the western shore of Tonga may be evidence of the most powerful volcano-triggered tsunami found to date. Up to 9 meters (30 feet) high and weighing up to 1.6 million kilograms (3.5 million pounds), the seven coral boulders are located 100 to 400 meters (300 to 1,300... view more (2008-09-26)

Extinct may not be forever for some species of Galapagos tortoises
Yale scientists report that genetic traces of extinct species of Galapagos tortoises exist in descendants now living in the wild, a finding that could spur breeding programs to restore the species, The report appears in Proceedings of the National Academy of Sciences.   view more (2008-09-23)

Magmatically triggered slow earthquake discovered at Kilauea Volcano, Hawaii
Kilauea experienced a new dike intrusion, where magma rapidly moved from a storage reservoir beneath the summit into the east rift zone and extended the rift zone by as much as 1 meter.   view more (2008-08-29)

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)

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)

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)

Fire under the ice
An international team of researchers was able to provide evidence of explosive volcanism in the deeps of the ice-covered Arctic Ocean for the first time.   view more (2008-06-26)

Lavas from Hawaiian volcano contain fingerprint of planetary formation
Hikers visiting the Kilauea Iki crater in Hawaii today walk along a mostly flat surface of sparsely vegetated basalt. It looks like parking lot asphalt, but in November and December 1959, it emitted the orange glow of newly erupted lava.   view more (2008-06-20)

1600 Eruption Caused Global Disruption
The 1600 eruption of Huaynaputina in Peru had a global impact on human society, according to a new study of contemporary records by geologists at UC Davis.   view more (2008-04-24)

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)

Dramatic developments at Kilauea Volcano: Scientists work to keep public safe and informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii this week have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm's way.   view more (2008-03-28)

A Fresh Look Inside Mount St. Helens
Volcanoes are notoriously hard to study. All the action takes place deep inside, at enormous temperatures. So geophysicists make models, using what they know to develop theories about what they don't know.   view more (2008-02-20)

First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active.   view more (2008-01-21)

News from Earth's magnetic field
It is widely known that the geomagnetic field shields our planet against highly energetic cosmic particles. The importance of the magnetic field for answering geological, tectonic or even archaeological questions is less known.   view more (2007-12-21)

Measurements link magma melting rate to tectonic plate subduction rate
Determining the origin and rate of magma production in subduction zone volcanoes is essential to understanding the formation of continental crust and the recycling of subducted materials back into Earth's mantle.   view more (2007-11-09)

How did chemical constituents essential to life arise on primitive Earth?
Experiments show that simple molecules can combine chemically rather than biologically to form the building blocks of DNA, the key component of all life forms. These processes might have taken place on primitive earth, but how they occur is an unsolved puzzle.   view more (2007-10-31)

Rapid analysis could cut health risks of volcanic ash
A new, rapid and cheap way of estimating the potential risk posed to human health by volcanic ash has been devised by a Durham University expert.   view more (2007-10-11)

Satellite methods for monitoring volcanic activity in the Andes Cordillera
The central part of the Andes situated between southern Peru and Chile bears 50 active or potentially volcanoes, spread along a 1500 km-long arc. These volcanic structures mostly rise to between 4000 and 7000 m, are very remote with abrupt slopes and are often cloaked in snow.   view more (2007-10-08)

Hydrothermal vents: Hot spots of microbial diversity
Thousands of new kinds of marine microbes have been discovered at two deep-sea hydrothermal vents off the Oregon coast by scientists at the MBL (Marine Biological Laboratory) and University of Washington's Joint Institute for the Study of Atmosphere and Ocean.   view more (2007-10-05)

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)

Expert challenges earthquake theory behind Indonesian mud volcano
A leading expert today repeated his assertion that an Indonesian mud volcano was almost certainly manmade despite a new study claiming the eruption might have been triggered by an earthquake.   view more (2007-08-01)
