Under Yellowstone lies a magma-filled formation that drives the national park鈥檚 famous geysers and other hydrothermal features. New research conducted by University of Utah geoscientists has located the top of the chamber 3.8 kilometers below Earth鈥檚 surface and characterized the upper reservoir鈥檚 structure, offering fresh insights into the risk of future eruptions.
Venus 鈥� a hot planet pocked with tens of thousands of volcanoes 鈥� may be even more geologically active near its surface than previously thought. New calculations by researchers at Washington University in St. Louis suggest that the planet鈥檚 outer crust may be constantly churning, an unexpected phenomenon called convection that could help explain many of the volcanoes and other features of the Venusian landscape.
MSU researchers glean photosynthetic insights from volcanic hot springs
An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the atmosphere from deep within the Earth long past their period of eruptions.
The Hubble Space Telescope has provided a dramatic and colorful close-up look at R Aquarii, one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars.
While working under Erika Rader, an assistant professor in the Department of Earth and Spatial Sciences at University of Idaho, a postdoctoral researcher identified a volcanic vent on Mars as a potential spatter cone and compared it to a spatter cone formed during the 2021 eruption of Fagradalsfjall in Iceland.
Computational modeling shows that plate tectonics weren鈥檛 necessary for early continents
In Review of Scientific Instruments, researchers from the University at Buffalo develop a tool for measuring the viscosity of lava that could increase our understanding of molten rock as well as better improve models of its movement, giving authorities crucial guidance for keeping people safe.
A University of Rhode Island oceanographer leading her first research cruise in the southern Pacific uncovered a surprise when her vessel looked below the waters in the Polynesian nation of Tonga.
A series of volcanic eruptions has rocked Iceland since 2021, as the Reykjanes Peninsula awakened from a nearly 800-year slumber. Climate change could be contributing to the increased volcanic activity, according to a University of Miami marine geoscientist.
In the three years since NASA鈥檚 Perseverance rover touched down on Mars, the NASA science team has made the daily task of investigating the red planet seem almost mundane.
Prof. Dr. Santi Pailoplee, Department of Geology, Faculty of Science, Chulalongkorn University, in collaboration with the Faculty of Archaeology, Silpakorn University, discovered a large number of rocks and rock formations on Khao Phanom Rung-Plai Bat, Chaloem Phra Kiat District, Buriram Province, which geologically signify human activity in the past, not natural formation.
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, i.e. explosive? These are key questions in volcanic hazard assessment and can also draw attention to volcanoes that appear to be inactive.
Researchers have discovered a series of large undersea sediment deposits in a region near Italy that were likely formed by an ancient volcanic supereruption.
GEOMAR researchers reconstruct historic volcanic eruption using 3D seismics
The dry, wind-swept summits of volcanoes in the Puna de Atacama of Chile and Argentina are the closest thing on Earth to the surface of Mars due to their thin atmosphere and freezing temperatures.
To bridge the knowledge gap between volcanologists and atmospheric scientists working on climate change and observing global systems, Cornell researchers have characterized volcanic ash samples from many explosive eruptions of a broad compositional range.
New research from the University of Oregon unpacks the geology behind lore, showing how seismically active faults on either side of the straight interact to create a narrow marine passage filled with geologic hazards.
What is the risk of a volcano erupting? To answer this question, scientists need information about its underlying internal structure.
