Shrinking glacier cover could lead to increased volcanic activity in Iceland, warn scientists in a new report.
Long Valley, California, has long defined the 'super-eruption.' About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish week, 760 cubic kilometers of lava and ash spewed out in the kind of volcanic cataclysm we hope never to witness. A new study shows that the giant body of magma -- molten rock -- at Long Valley was much cooler before the eruption than previously thought.
Volcanic eruptions have been known to cool the global climate, but they can also exacerbate the melting of ice sheets, according to a new paper.
Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Such collapses are rather common events during the evolution of a large volcanic edifice, often with dramatic consequences such as tsunami and volcano explosions. These catastrophic events interact with the magmatic activity of the volcano, as new research suggests.
More than 11 years after the Lusi mud volcano first erupted on the Indonesian island of Java, researchers may have figured out why the mudflows haven't stopped: deep underground, Lusi is connected to a nearby volcanic system.
Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.
Researchers have determined that the Pacific Northwest was home to one of the Earth's largest known volcanic eruptions, a millennia-long spewing of sulfuric gas that blocked out the sun and cooled the planet. Only two other eruptions -- the basalt floods of the Siberian Traps and the Deccan Traps -- were larger, and they led to two of the Earth's great extinctions.
Building on existing information and databases relating to volcanic fatalities, scientists have, for the first time, been able to classify victims by activity or occupation and look at the distance of their death from the volcano.
Geologists have analyzed volcanic data from the Messinian salinity crisis in the Mediterranean Sea, when the Strait of Gibraltar was blocked and the Mediterranean temporarily isolated from the Atlantic. After testing various scenarios, the geologists concluded that the increase in magmatic activity could only be explained by the almost total drying out of the Mediterranean.
Geophysicists use a new model to conclude that volcanic hot spots around the globe aren't moving as fast as recently thought.
Researchers show that lake sediments preserved within ancient supervolcanoes can host large lithium-rich clay deposits. A domestic source of lithium would help meet the rising demand for this valuable metal, which is critical for modern technology.
Researchers have shown an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
