Nea Kameni volcano movement captured by Envisat
Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to be exploited for the long-term monitoring of volcanoes. View More (2012-05-23)
Scientists 'read' the ash from the Icelandic volcano 2 years after its eruption
In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. View More (2012-05-14)
Yellowstone 'super-eruption' less super, more frequent than thought
The Yellowstone "super-volcano" is a little less super-but more active-than previously thought. View More (2012-04-30)
Forensic science used to determine who's who in pre-Columbian Peru
Analysis of ancient mitochondrial DNA (mtDNA) has been used to establish migration and population patterns for American indigenous cultures during the time before Christopher Columbus sailed to the Americas. View More (2012-04-23)
EARTH: Foretelling next month's tornadoes
Tornadoes are notoriously difficult to forecast, with often deadly results: In 2011, tornadoes in the U.S. killed more than 550 people, a higher death toll than in the past 10 years combined. View More (2012-04-04)
EARTH: Danger in paradise -- the hidden hazards of volcano geotourism
Beautiful views and exotic thrills draw millions of tourists to volcanic sites each year. Previously frequented by smaller numbers of experienced hikers and trained tour guides, today's volcanic sites are plagued by throngs of novice hikers, who are often ill-prepared and uneducated about the risks of volcano geotourism.

Two New NASA LRO Videos: See Moon's Evolution, Take a Tour
In honor of 1,000 days in orbit, the NASA Lunar Reconnaissance Orbiter (LRO) team at NASA Goddard Space Flight Center in Greenbelt Md. has released two new videos. View More (2012-03-15)
Lava Fingerprinting Reveals Differences Between Hawaii's Twin Volcanoes
Hawaii's main volcano chains--the Loa and Kea trends--have distinct sources of magma and unique plumbing systems connecting them to the Earth's deep mantle, according to UBC research published this week in Nature Geoscience, in conjunction with researchers at the universities of Hawaii and Massachusetts.

Pesky ants found in Hawaii demonstrate invasive characteristics
A common pest in the mainland United States known for its tropical smell now has a tropical habitat to go along with it. View More (2011-11-02)
Mapping the formation of an underwater volcano
On Oct. 9 an underwater volcano started to emerge in waters off El Hierro Island in the Canaries, Spain. Researchers of the Spanish Institute of Oceanography (IEO, Ministry of Science and Innovation) only needed 15 days to map its formation in high resolution. View More (2011-10-31)
Fiery volcano offers geologic glimpse into land that time forgot
The first scientists to witness exploding rock and molten lava from a deep sea volcano, seen during a 2009 expedition, report that the eruption was near a tear in the Earth's crust that is mimicking the birth of a subduction zone. View More (2011-10-20)
CSI-style investigation of meteorite hits on Earth
Volcanologists from the Universities of Leicester and Durham have forensically reconstructed the impact of a meteorite on Earth and how debris was hurled from the crater to devastate the surrounding region. View More (2011-10-18)
Scientists find possible trigger for volcanic 'super-eruptions'
The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions. View More (2011-10-13)
Tenerife geology discovery is among 'world's best'
Volcanologists from the University of Leicester have uncovered one of the world's best-preserved accessible examples of a monstrous landslide that followed a huge volcanic eruption on the Canarian island of Tenerife. View More (2011-10-03)
Deep recycling in the Earth faster than thought
The recycling of the Earth's crust in volcanoes happens much faster than scientists have previously assumed. Rock of the oceanic crust, which sinks deep into the earth due to the movement of tectonic plates, reemerges through volcanic eruptions after around 500 million years. View More (2011-08-11)
Guam researcher studies Mount Pinatubo ecosystem recovery
University of Guam ecologist Thomas Marler recently mobilized efforts to characterize the vegetation that has recovered following the eruption of Mount Pinatubo, Philippines. View More (2011-08-08)
Earth from Space: A gush of volcanic gas
This image shows the huge plume of sulphur dioxide that spewed from Chile's Puyehue-Cordón Caulle Volcanic Complex, which lies in the Andes about 600 km south of Santiago. View More (2011-06-13)
NASA provides a 2-satellite view and video of the Chilean volcano eruption
NASA's Aqua satellite and the GOES-13 satellite both captured their own unique views of the eruption of the Puyehue-Cordón Caulle volcano in Chile this week. One satellite provided a high-resolution image of the ash plume while the other provided a video showing the plumes movement over several days. View More (2011-06-10)
Novel ash analysis validates volcano no-fly zones
Planes were grounded all over Europe when the Eyjafjallajökull volcano erupted in Iceland last year. View More (2011-04-26)
Before the explosion -- volcano's warning tremors explained
No matter their size or shape, explosive volcanoes produce tremors at similar frequencies for minutes, days or weeks before they erupt. View More (2011-02-24)
