Lasering lava to forecast volcanic eruptions
University of Queensland researchers have optimised a new technique to help forecast how volcanoes will behave, which could save lives and property around the world.
Minoan eruption survey improves volcanic risk assessments
An international team of researchers led by marine geoscientist Dr. Jens Karstens of GEOMAR Helmholtz Centre for Ocean Research Kiel has now, for the first time, combined the latest geophysical and geological methods to resurvey the Minoan eruption, which took place 3,600 years ago, of the Greek island of Santorini.
2022 Tongan volcanic explosion was largest natural explosion in over a century, new study finds
The 2022 eruption of a submarine volcano in Tonga was more powerful than the largest U.S. nuclear explosion, according to a new study led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Khaled bin Sultan Living Oceans Foundation.
Malformed seashells, ancient sediment provide clues about Earth’s past
Nearly 100 million years ago, the Earth experienced an extreme environmental disruption that choked oxygen from the oceans and led to elevated marine extinction levels that affected the entire globe.
Exotic clasts in Chang’e-5 samples indicate unexplored terrane on moon
The Chang’e-5 mission touched down in the Mons Rümker region of the northern Oceanus Procellarum of the Moon and returned 1.731 kg of lunar regolith.
Scientists identify the highest-ever recorded volcanic plume
Using images captured by satellites, researchers in the University of Oxford’s Department of Physics and RAL Space have confirmed that the January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano produced the highest-ever recorded plume.
Volcano’s Eruption Will Help Scientists Plot Weather, Climate
As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha’apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.
Great Timing, Supercomputer Upgrade Lead to Successful Forecast of Volcanic Eruption
In the fall of 2017, geology professor Patricia Gregg and her team had just set up a new volcanic forecasting modeling program on the Blue Waters and iForge supercomputers.
Volcanic eruptions contributed to collapse of China dynasties
Volcanic eruptions contributed to the collapse of dynasties in China in the last 2,000 years by temporarily cooling the climate and affecting agriculture, according to a Rutgers co-authored study.
Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s atmosphere
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.
New ice core data tracks climate-changing eruptions
An international team of scientists has analyzed chemicals in an ice core from West Antarctica to compile the most accurate chronology of volcanic eruptions during the last 11,000 years produced thus far.
