To better predict explosive, fiery volcanic activity, Cornell geologists have proposed a new classification system to discern the stages of a volcano’s unrest – as seen from smart, perceptive satellites.
Volcanic tsunamis - those caused by an underwater eruption - are as devastating as they are abrupt. Richards Sunny, a doctoral candidate in the Department of Ocean Engineering, is developing and improving simulations to map, predict and research volcanic tsunamis.
Researchers at the University of Rhode Island (URI) used San Diego Supercomputer Center’s (SDSC) Comet supercomputer to show that high-performance computer modeling can accurately simulate tsunamis from volcanic events. Such models could lead to early-warning systems that could save lives and help minimize catastrophic property damage.
A natural experiment created by an active volcano gives new insight into the long-term negative impacts of human colonisation of tropical forest islands. The findings are published in the British Ecological Society journal, Journal of Ecology.
A new approach to analyzing seismic data reveals deep vertical zones of low seismic velocity in the plumbing system underlying Alaska's Cleveland volcano, one of the most-active of the more than 70 Aleutian volcanoes
Presentations on natural disasters such as earthquakes, volcanoes and their impacts will be held in Scott Hall and are open to the public at the Rutgers Geology Museum’s 52nd Annual Open House. There will also be hands-on activity sessions for kids, a mineral sale and rock and mineral identification in Scott Hall, and make-and-take stations in the Rutgers Geology Museum. Field Station Dinosaurs will bring its baby Hadrosaurus puppet and will also offer hands-on activities for visitors. All events are free and no preregistration is required.
Kolumbo volcano—which sits 500 meters below the surface within the fault-heavy Hellenic Volcanic Arc just off Santorini—is the Aegean Sea’s most active and potentially dangerous volcano.
Six scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have been named Fellows of the American Association for the Advancement of Science (AAAS).
Lawrence Livermore National Laboratory (LLNL) scientists are now using plasma physics to predict the characteristics of volcanic hazardous ash plumes.
Photographers and others with a keen eye have noticed that sunrises and sunsets have become a lot more purple in the U.S. New measurements from a high-altitude balloon could explain why.
Volcanoes are often feared for their destructive power, but a new study reminds us that they can foster new growth.
An international team of subsurface explorers from the University of Adelaide in Australia and the University of Aberdeen in Scotland have uncovered a previously undescribed ‘Jurassic World’ of around 100 ancient volcanoes buried deep within the Cooper-Eromanga Basins of central Australia.
While it's important to evaluate geoengineering proposals from an informed position, the best way to reduce climate risk is to reduce emissions
A volcano will not send out an official invitation when it’s ready to erupt, but a team of researchers suggest that scientists who listen and watch carefully may be able to pick up signs that an eruption is about to happen. In a study of Hawaii's Kīlauea volcano, the researchers reported that pressure changes in the volcano’s summit reservoirs helped explain the number of earthquakes — or seismicity — in the upper East Rift Zone. This zone is a highly active region where several eruptions have occurred over the last few decades, including a spectacular one in 2018.
Floating air particles following disasters and other geological events can have a lasting impact on life on Earth, and a new model drawing on chaos theory looks to help predict how these particles move, with an eye toward applications for geoengineering. Using available wind data, Tímea Haszpra developed a model for following particles as they travel around the globe. Using it, she has generated maps that can be used to predict how particles will be dispersed above the world.
