Stromboli"s "rejuvenation" heralds era of more variable volcanic eruptions
An unexpected series of eruptions at Stromboli may be due to changes in the volcano's internal "plumbing.".....»»
11 bodies recovered after volcanic eruption in Indonesia, and 12 climbers are still missing
The bodies of 11 climbers were recovered Monday a day after a furious eruption of the Mount Marapi volcano as Indonesian rescuers searched for 12 apparently still missing......»»
Some high-threat volcanoes are severely understudied: Study
The Cascade Volcanic Arc stretches from Northern California to southern British Columbia and contains more than a dozen volcanoes. The U.S. Geological Survey classifies 11 of them, including Mount Baker and Mount Hood, as "very high threat," meaning.....»»
More than a meteorite: New clues about the demise of dinosaurs
What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the tradi.....»»
A new theory to explain the nature of volcanic fountaining
A multi-institutional team of Earth scientists, meteorologists, geologists and volcanologists has developed a new theory to explain the nature of volcanic fountaining. In their project, reported in the journal Nature Communications, the group studied.....»»
Global view of Io"s volcanic activity suggests that tidal heating is concentrated within its upper mantle
A team of volcanologists and planetary scientists from NASA's Jet Propulsion Laboratory, California Institute of Technology, the University of Arizona, and Arizona State University has found via study of a newly created global view of Io's volcanic a.....»»
Listen to the seismic sounds as Iceland braces for likely volcanic eruption

Iceland on high alert for volcanic eruption—what we know so far
The Reykjanes peninsula in south-west Iceland trembled with an intense swarm of earthquakes on the afternoon of Friday November 10. Hundreds of quakes were detected on the regional networks of seismometers and several were strong enough to be felt in.....»»
Q&A: Is a volcano about to erupt in Iceland? Expert explains the telltale signs that an eruption might occur
Residents of Grindavik, a fishing town in southwestern Iceland, have evacuated and a state of emergency has been declared, as local authorities say a volcanic eruption may be imminent......»»
Quakes rock southwestern Iceland as volcanic eruption looms
Iceland declared a state of emergency on Friday after a series of powerful earthquakes rocked the country's southwestern Reykjanes peninsula, in what could be a precursor to a volcanic eruption......»»
Volcanic eruption: Scientists perform volcanic scenarios to develop response plan
What would happen if a volcano were to erupt tomorrow in New Mexico? How prepared as we as a society for an event like this to occur? When volcanic unrest occurs, both academic and government agencies need to have advanced fundamental understanding o.....»»
Study shows historical volcanic eruptions triggered short-term global cooling
New international research led by the University of St Andrews reveals historical high latitude volcanic eruptions caused dramatic, but short-lived climate cooling......»»
Large herbivores such as elephants, bison and moose shown to contribute to tree diversity
Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiver.....»»
One of California"s riskiest volcanoes is very active. Is an eruption coming?
One of California's riskiest volcanoes has for decades been undergoing geological changes and seismic activity, which are sometimes a precursor to an eruption, but—thankfully—no supervolcanic eruptions are expected......»»
What caused the volcanic tsunami that devastated a Greek island 373 years ago?
Kolumbo underwater volcano's 1650 eruption killed 70 people on Santorini Island, Greece. Enlarge / This view from an international volcano monitoring system shows the Kolumbo volcanic crater on the seafloor. (credit: SANTORY ).....»»
Io has 266 active volcanic hotspots linked by a global magma ocean, finds study
Jupiter's Io stands apart from the solar system's other moons, with its numerous volcanoes and its surface dominated by lava flows. Io's surface volcanism was confirmed in 1979 when the Voyager spacecraft imaged it, but its volcanic nature isn't dupl.....»»
Mystery of volcanic tsunami solved after 373 years
The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers led by Dr. Jens Karstens from the GEOMAR Helmholtz Centre for Ocean Resea.....»»
Variable star RZ Piscium has a compact and highly perturbed debris disk, study finds
Using NASA's Spitzer and WISE space telescopes, astronomers from the Steward Observatory and elsewhere have observed a well-known variable star designated RZ Piscium. They found that the star's circumstellar debris disk is compact and highly perturbe.....»»
Adding crushed rock to farmland pulls carbon out of the air, field test shows
Adding crushed volcanic rock to cropland could play a key role in removing carbon from the air. In a field study, scientists at the University of California, Davis, and Cornell University found the technology stored carbon in the soil even during an.....»»
Washington"s volcanoes are experiencing seismic tremors from an unlikely source—glaciers
Most people think of seismic activity as the result of movement along faults or of violent volcanic eruptions. But seismic events can have other causes, including floods and even large crowds of excited fans—such as those at Taylor Swift's recent S.....»»
Why Have Climate Catastrophes Toppled Some Civilizations but Not Others?
Researchers are honing in on what helps societies survive climate shocks, like the volcanic eruptions that helped fell the Roman Empire or the drought that plagued the ancient Mayans......»»
