NISAR, the soon-to-launch radar satellite from NASA and the Indian Space Research Organization (ISRO), will measure some key Earth vital signs, from the health of wetlands to ground deformation by volcanoes to the dynamics of land and sea ice......»»
How magma and water shaped the iconic Columbia River Gorge
University of Oregon researchers are adding new details to the geological history of the iconic Columbia River Gorge, a wide river canyon that cuts through the volcanic peaks of the Cascades along the border between Oregon and Washington......»»
Piezoelectric-enhanced p-n junctions in photoelectrochemical systems
Photoelectrochemical (PEC) water splitting is a potentially feasible strategy for converting solar energy to green hydrogen. However, current PEC systems suffer from relatively low charge separation efficiency and sluggish water oxidation reaction, w.....»»
Mapping magma chambers under the Hunga volcano before and after the 2022 eruption

Planetary scientists simulate oxidation of iron by giant impact during atmospheric evolution of early Earth
Giant-impact driven redox processes in the atmosphere and magma ocean may have played crucial roles during the evolution of the Earth. However, the absence of rock records from the time or era makes it challenging to understand these processes......»»
Long dormant volcanoes can erupt rapidly and explosively, says Ciomadul study
Can a volcano erupt after tens of thousands of years of dormancy? If so, how can this be explained and what makes volcanic eruptions more dangerous?.....»»
Scientists investigate Socorro Magma Body to enhance volcanic understanding
Although volcanoes have been extensively studied, unraveling the mysteries of the underlying magma transport proves to be a challenging pursuit. Grant Block, a graduate student in The University of New Mexico's Department of Physics & Astronomy, rece.....»»
Seafloor shapes on the flanks of mid-ocean ridges linked to magma supply
At nearly 65,000 kilometers long, the mid-ocean ridge system is the longest mountain range in the world. Running beneath the ocean's surface, mid-ocean ridges are formed at divergent plate boundaries, where tectonic plates stretch apart and magma ris.....»»
Some high-threat volcanoes are severely understudied: Study
The Cascade Volcanic Arc stretches from Northern California to southern British Columbia and contains more than a dozen volcanoes. The U.S. Geological Survey classifies 11 of them, including Mount Baker and Mount Hood, as "very high threat," meaning.....»»
To study radioactive neptunium and plutonium, researchers establish a novel chemistry
Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium......»»
Image: Italy"s Mount Etna spews lava
One of the world's most active volcanoes, Mount Etna, erupted on Sunday—spewing lava and clouds of ash high over the Mediterranean island of Sicily. This image, captured on 13 November by the Copernicus Sentinel-2 mission, has been processed using.....»»
One of California"s riskiest volcanoes is very active. Is an eruption coming?
One of California's riskiest volcanoes has for decades been undergoing geological changes and seismic activity, which are sometimes a precursor to an eruption, but—thankfully—no supervolcanic eruptions are expected......»»
