Scientists identify flank instability at a volcano with history of collapse — ScienceDaily

Landslides caused by the collapse of unstable volcanoes are one of the major dangers of volcanic eruptions. A method to detect long-term movements of these mountains using satellite images could help identify previously overlooked instability at some volcanoes, according to Penn State scientists. “Whenever there is a large volcanic eruption, there is a chance that […]

There’s lots of water in the world’s most explosive volcano — ScienceDaily

There isn’t much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka’s Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last gigantic blast occurred in 1964, […]

Rediscovery of the ‘extinct’ Pinatubo volcano mouse

The rediscovered volcano mouse, thought to be extinct. Credit: Danny Balete, Field Museum In June 1991, Mount Pinatubo, a volcanic peak on the Philippine Island of Luzon, literally blew its top. It was the second-most powerful volcanic eruption of the 20th century, ten times stronger than Mount Saint Helens, and its effects were devastating. Lava […]

There’s lots of water in the world’s most explosive volcano

Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last gigantic blast occurred in 1964, creating a new crater and covering an area of nearly 100 square kilometers with pyroclastic flows. But Shiveluch is actually currently erupting, as it has been for over 20 years. Credit: Michael Krawczynski, Washington […]

Semeru volcano on Indonesia’s Java island spews hot clouds

In this photo released by Indonesia’s National Disaster Mitigation Agency (BNPB) Mount Semeru spews volcanic material during an eruption in Lumajang, East Java, Indonesia, Saturday, Jan. 16, 2021. The highest volcano on Indonesia’s most densely populated island of Java, spewed hot clouds as far away as 4.5 kilometers (nearly 3 miles) on Saturday. (National Disaster […]

Hawaii’s Kilauea volcano erupts with dramatic lava fountains

Hawaii’s Kilauea volcano erupted beginning Sunday (Dec. 20) night local time, with dramatic lava fountains and huge puffs of gas and steam being launched from the summit crater called Halemaʻumaʻu, the Hawaii Volcano Observatory (HVO), part of the U.S. Geological Survey (USGS), reported. Though the shield volcano is one of Earth’s most active volcanoes, constantly […]

New Volcano, Old Caldera – Eos

In May of 2018, a barrage of earthquakes struck Mayotte, the seismically quiet easternmost island of the Comoros archipelago, which stretches between Africa and Madagascar. After months of investigating the unexpected, intense seismic activity, French scientists discovered a new submarine volcano in the Indian Ocean approximately 50 kilometers east of the island. This […]

Can Volcano Forecasting Make Visiting Whakaari Safe Again?

One year ago, the volcano on Whakaari/White Island erupted in New Zealand, killing nearly two dozen tourists and critically injuring many others. Survivors and family members of the victims have criticized companies for holding tours during heightened volcanic activity. Now, scientists at the University of Auckland have invented a new way to forecast […]
