Stromboli"s "rejuvenation" heralds era of more variable volcanic eruptions
An unexpected series of eruptions at Stromboli may be due to changes in the volcano's internal "plumbing.".....»»
Juno completes its closest flyby of Io yet
Jupiter's ocean moons capture most of our attention because of their potential habitability. But Io, Jupiter's bad-boy volcanic moon, is in a class of its own. There's nothing else like it in the solar system, and NASA's Juno spacecraft captured new.....»»
Cataclysmic variable Swift J0503.7-2819 investigated by researchers
Using various spacecraft and ground-based observatories, an international team of astronomers has performed a multi-wavelength study of a cataclysmic variable system known as Swift J0503.7-2819. Results of the study, published October 11 on the pre-p.....»»
Constructing a global variable-resolution atmospheric physico-chemical coupling simulation framework
A research team led by Prof. Zhao Chun from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has developed a global variable-resolution modeling framework and conducted research using atmospheric sand.....»»
High mountains, high diversity: For how long have the Andes controlled South America"s biodiversity?
With the aid of stable hydrogen isotopes in volcanic glass, an international research team, including Senckenberg geoscientist Prof. Dr. Andreas Mulch, has studied the uplift history of the Andes Plateau. In their study, published in the journal Proc.....»»
Lethal climate change millions of years ago was due to volcanic eruptions, scientists conclude
Climate change that has occurred over the past 260 million years and brought about mass extinctions of life during these periods was due to massive volcanic eruptions and subsequent environmental crises, concludes a team of scientists......»»
Increase in forest fires may damage the crucial ozone layer
All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher Johan Friberg studies part.....»»
Discovery of massive undersea water reservoir could explain New Zealand"s mysterious slow earthquakes
Researchers have discovered a sea's worth of water locked within the sediment and rock of a lost volcanic plateau that's now deep in the Earth's crust. Revealed by a 3D seismic image, the water lies two miles under the ocean floor off the coast of Ne.....»»
Filling the data gap for volcanic ash effects on Earth systems
Volcanic ash is no ordinary dust: It gets injected into the atmosphere, climbs to the stratosphere, impacts climate, powders roadways and clogs jet engines......»»
Potential source of ancient methane eruption identified
Seabed eruptions tied to the start of a sudden warming event 55 million years ago. Enlarge / 3D seismic image showing the crater of the Modgunn Vent and others like it. The cratered surface labelled "BVU" is the seabed of 56 mill.....»»
A string of volcanic tremors raises fears of mass evacuations in Italy
Hundreds of small tremors have shaken a densely populated volcanic area west of the Italian city of Naples in recent weeks, pushing the government to quickly redraft mass evacuation plans, even though experts don't see an imminent risk of eruption......»»
Optimizing continuous-variable functions with quantum annealing
Quantum annealing (QA) is a cutting-edge algorithm that leverages the unique properties of quantum computing to tackle complex combinatorial optimization problems (a class of mathematical problems dealing with discrete-variable functions)......»»
Glaciers can give us clues about when a volcano might erupt
Globally, there is about one volcano erupting each week. Volcanic unrest kills an average of 500 people every year and costs the global economy roughly US$7 billion (£5.7 billion). With one in 20 people living somewhere at risk of volcanic activity,.....»»
Study removes human bias from debate over dinosaurs" demise
To help resolve the scientific debate over whether it was a giant asteroid or volcanic eruptions that wiped out the dinosaurs and most other species 66 million years ago, Dartmouth researchers tried a new approach—they removed scientists from the d.....»»
Modeling shows fires from volcanic activity could greatly increase area affected by eruption
An international research team, including researchers from GNS Science, has released a study into the potential threat of fires caused by volcanic eruptions. The study investigated how far fires ignited by hot rock projectiles from a volcanic eruptio.....»»
Researchers create formula for first synthetic sugarcane molasses with fully reproducible composition
Molasses, a broad term used to describe concentrated sugarcane or sugarbeet juice solutions after removal of sucrose crystals, are an industrial byproduct of the raw sugar production process. Natural molasses have variable compositions that are not e.....»»
Study sheds new light on strange lava worlds
Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system......»»
Venus on Earth: NASA"s VERITAS science team studies volcanic Iceland
With its crushing atmospheric pressure, clouds of sulfuric acid, and searing surface temperature, Venus is an especially challenging place to study. But scientists know that observing its surface can provide key insights into the habitability and evo.....»»
Tonga volcano unleashed fastest ever undersea flows: study
An unprecedentedly violent volcanic eruption that triggered a tsunami off the Pacific island nation of Tonga in 2022 unleashed the fastest underwater currents ever recorded, according to a study published on Thursday......»»
Exploring Io"s volcanic activity via Hubble and Webb telescopes
The two most powerful space telescopes ever built, NASA's James Webb Space Telescope (JWST) and Hubble Space Telescope, are about to gather data about the most volcanically body in the entire solar system, Jupiter's first Galilean moon, Io......»»
North Atlantic volcanic activity was a major driver of climate change 56 million years ago, study finds
The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C......»»
