What are mud volcanoes?
Rice farmers living in Sidoarjo Regency, Indonesia, awoke to a strange sight on May 29, 2006. The ground had ruptured overnight and was spewing out steam......»»
Image: Italy"s Mount Etna spews lava
One of the world's most active volcanoes, Mount Etna, erupted on Sunday—spewing lava and clouds of ash high over the Mediterranean island of Sicily. This image, captured on 13 November by the Copernicus Sentinel-2 mission, has been processed using.....»»
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......»»
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.....»»
An unusual crater on Pluto might be a supervolcano
Pluto with a super-cryovolcano? Why not! All the elements are there, just not in the way we normally think of volcanoes. And cryovolcanoes are the reason why Pluto's surface looks the way it does. A recent research paper explains why Pluto could be t.....»»
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.....»»
New research finds that ancient carbon in rocks releases as much carbon dioxide as the world"s volcanoes
A new study led by the University of Oxford has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large CO2 source, rivaling that of volcanoes. The results, published today in the jour.....»»
An Epic Fight Over What Really Killed the Dinosaurs
A deep learning model has joined a vigorous debate over whether volcanoes began dinosaur doomsday well before the asteroid hit......»»
Glaciers could provide powerful new volcano monitoring tool
Glaciers could become a powerful tool for monitoring some volcanoes, according to new research that shows for the first time how the altitude of glaciers located on volcanoes could signal future unrest including the threat of an eruption......»»
Carbon dioxide, not water, triggers explosive basaltic volcanoes
Geoscientists have long thought that water—along with shallow magma stored in Earth's crust—drives volcanoes to erupt. Now, thanks to newly developed research tools at Cornell, scientists have learned that gaseous carbon dioxide can trigger explo.....»»
Lasering lava to forecast volcanic eruptions
University of Queensland researchers have optimized a new technique to help forecast how volcanoes will behave, which could save lives and property around the world. The research is published in Science Advances......»»
Large sub-surface granite formation signals ancient volcanic activity on moon"s dark side
A large formation of granite discovered below the lunar surface likely was formed from the cooling of molten lava that fed a volcano or volcanoes that erupted early in the moon's history—as long as 3.5 billion years ago......»»
New research shows climate change will increase impacts of volcanic eruptions
Volcanic disasters have been studied since Pompeii was buried in 79 A.D., leading the public to believe that scientists already know why, where, when and how long volcanoes will erupt. But Jonathan Fink, volcanologist and director of the Digital City.....»»
Research reveals sources of carbon dioxide from Aleutian-Alaska Arc volcanoes
Scientists have wondered what happens to the organic and inorganic carbon that Earth's Pacific Plate carries with it as it slides into the planet's interior along the volcano-studded Ring of Fire......»»
Sinking seamount offers clues to slow motion earthquakes
Scientists have long puzzled over what happens when seamounts—mountains and volcanoes on the seafloor—are pulled into subduction zones. Now, new research from The University of Texas at Austin shows that when seamounts sink, they leave behind a t.....»»
Unlocking early Earth chemistry: Salt-induced changes in polyester microdroplet structure
Billions of years ago, Earth was an extremely hostile planet with active volcanoes, a harsh atmosphere, and no life. This prebiotic Earth, however, was filled with a wide array of abiotic organic molecules derived from its early environment, which un.....»»
Philippines evacuates people near Mayon Volcano, where more unrest indicates eruption may be coming
Philippine troops, police and rescue workers began forcibly evacuating residents near Mayon Volcano on Friday as its increasing unrest indicated a violent eruption of one of the country's most active volcanoes is possible within weeks or days......»»
Petit-spot volcanoes involve deepest known submarine hydrothermal activity, may release methane
Underwater volcanoes on the Earth's crust are active contributors of many different elements to the oceanic environment. Hence, they play an important role in biogeochemical and chemosynthetic cycles of the ocean. Although there have been many studie.....»»
Indonesia"s Merapi volcano erupts, spewing "avalanche" of lava
Indonesia's Mount Merapi, one of the world's most active volcanoes, erupted on Tuesday, spewing lava more than two kilometers from the crater......»»
Thriving in the face of adversity: Resilient gorillas reveal clues about overcoming childhood misfortune
In 1974, an infant mountain gorilla was born in Volcanoes National Park in Rwanda. Researchers named him Titus. As is typical for young gorillas in the wild, Titus spent the first years of his life surrounded by his mother, father and siblings, as we.....»»
Newly discovered exoplanet could have liquid water, lots of volcanoes
The likely volcanoes should ensure that it has an atmosphere, too. Enlarge / An artist's conception of what a volcano-rich exoplanet might look like. (credit: NASA’s Goddard Space Flight Center/Chris Smith) For most of.....»»
