May 27, 2024 By analyzing the dynamics of 12 back-to-back explosions that happened in 2018, researchers describe a new type of volcanic eruption mechanism. The explosions were driven by sudden pressure increases ...
Apr. 11, 2023 Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new ...
Oct. 20, 2022 Magma beneath long-dormant Mount Edgecumbe volcano in Southeast Alaska has been moving upward through Earth's crust, according to research the Alaska Volcano Observatory rapidly produced using a ...
Nov. 4, 2024 Fifteen minutes before the massive January 2022 eruption of the Hunga Tonga-Hunga Ha'apai volcano, a seismic wave was recorded by two distant seismic stations. The researchers propose that the ...
June 9, 2023 The new study used a model of volcano fracturing to interpret patterns of earthquakes and ground uplift, and concluded that parts of the volcano had been stretched nearly to breaking ...
May 1, 2025 A new study has investigated the use of a new monitoring technique for early warning of a volcanic eruption. The research team compared the earthquake signals during two eruptions of Ontake Volcano ...
Aug. 31, 2023 What is the risk of a volcano erupting? To answer this question, scientists need information about its underlying internal structure. However, gathering this data can take several years of fieldwork, ...
Oct. 26, 2023 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 has now surveyed ...
July 21, 2025 Beneath Yellowstone’s stunning surface lies a hyperactive seismic world, now better understood thanks to machine learning. Researchers have uncovered over 86,000 earthquakes—10 times more than ...
Feb. 22, 2024 A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found ...
