On Saturday, a giant 3-kilometre fissure opened up in the ground on the Reykjanes Peninsula in Iceland, sending a river of molten lava flowing across the landscape. The eruption is the fourth and largest to hit the region since December. It has forced some 3,800 residents from the nearby town of Grindavik to evacuate. Many have said they have no plans to return. Another view of when the #eruption started a short while ago in #Iceland. The ground just opens up and boom! Just amazing!!! 🤩…

Incorporating crushed volcanic rocks into agricultural fields can significantly contribute to carbon dioxide reduction, with tropical regions offering the most promise for this climate mitigation strategy. Credit: SciTechDaily.com Adding crushed volcanic rocks to agricultural fields can both improve the soil and suck down carbon dioxide. Doing so in the hot, humid tropics would be most efficient, a new study finds.Enhanced rock weathering makes use of a natural geologic process to store carbon long-termApplying 10 tons of…

Crew aboard the International Space Station photographed the eruption of Mount Etna in Sicily in October 2002. Ashfall was reported more than 350 miles away. When it comes to explosive power, however, no eruption in modern times can compare with a super eruption—which hasn't occurred for tens of thousands of years.

An instrument on this spacecraft called “JunoCam” returned spectacular,…

NASA’s Juno spacecraft has completed yet another flyby of Io, Jupiter’s highly volcanic moon. Coming eerily close to the moon, the small spacecraft was able to capture images of twin volcanic plumes on Io’s surface, sending material erupting into space.This new flyby was only the second-closest flyby that Juno made to Io. It came within 1,500 kilometers (930 miles) of the moon’s surface. During this stellar rendevous, the spacecraft captured evidence of the various volcanos believed to pockmark the surface of…

The chaos of lightning crackling through the sky has been speculated to play a key role in freeing elements like phosphorus, making it more accessible to burgeoning life on ancient Earth.Now, scientists have found geological evidence that the lightning discharges associated with volcanic events may have also played a role in nitrogen fixation, making it available for biological processes too.Since Earth is thought to have once been significantly more volcanically volatile in its younger years, the discovery suggests that…

On February 3, NASA’s Juno spacecraft captured images of two volcanic plumes on Jupiter’s moon Io, possibly indicating activity from either two vents of a single volcano or two separate volcanoes. The Juno team plans to analyze this event in conjunction with data from previous missions to enhance our understanding of Io’s volcanic dynamics.

NASA’s Juno spacecraft captured new images of Jupiter’s moon Io during its latest flyby, coming within an eerily close distance of the most volcanically active world in the solar system for a second time in less than two months. The close encounter also shows what appears to be a pair of plumes erupting from the moon’s surface.

NASA's Juno spacecraft snapped detailed images of the most volcanically active world in our Solar System on Saturday. During this close fly-by, the spacecraft spotted plumes of volcanic activity erupting from Io's surface in real-time.This encounter was the second in a set of two close fly-bys designed to provide new insight into the fiery phenomena that lurk beneath Io's surface.They are humanity's closest encounters with Io in the last 22 years, surveying it at a distance of 930 miles. Here are the striking first…
