A new model shows how brine on Jupiter's moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings, which are important for the upcoming Europa Clipper mission, may explain cryovolcanic eruptions across icy bodies in the solar system.
Scientists have detected what they say are the sediments of a huge ancient lake bed sealed more than a mile under the ice of northwest Greenland--the first-ever discovery of such a sub-glacial feature anywhere in the world.
A group of Skoltech scientists developed machine learning (ML) algorithms that can teach artificial intelligence (AI) to determine oil viscosity based on nuclear magnetic resonance (NMR) data. The new method can come in handy for the petroleum industry and other sectors, which have to rely on indirect measurements to characterize a substance.
International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active -- erupting for 30 million years -- fuelled by a constantly moving 'conveyor belt' of magma.
The high-pressure mineral Donwilhelmsite, recently discovered in the lunar meteorite Oued Awlitis 001 from Apollo missions, is important for understanding the inner structure of the earth.
A two-volume atlas presents and explains the impact sites of meteorites and asteroids worldwide
University of Tsukuba researchers have conducted detailed structural analyses of a fault zone in central Japan to identify the specific conditions that lead to devastating earthquake. The seismic slip processes that were inferred based on the measurements may be applicable to other subduction zones, such as those below the oceans. The gathered data could be applied in future attempts to describe or model the subduction earthquakes that lead to ground shaking and tsunami risk.
Specially-adapted drones developed by an international team have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions. The cutting-edge research at Manam volcano in Papua New Guinea is also improving scientists' understanding of how volcanoes contribute to the global carbon cycle, key to sustaining life on Earth.
Stromboli, the 'lighthouse of the Mediterranean', is known for its low-energy but persistent explosive eruptions, behaviour that is known scientifically as Strombolian activity. Occasionally, however, more intense and sudden explosions occur, most recently in July and August last year (2019). These are known as 'Strombolian paroxysms'. During such events several of Stromboli's craters are active simultaneously and much greater volumes of pyroclastic materials are erupted than is usual for the volcano.
The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this feedback by exploring long-term if-then-scenarios.
