Researchers found that magma plumbing systems beneath volcanoes can fluctuate between solid- and liquid-dominated states, providing new insights into volcano evolution. Ancient Carlingford Mountain fossilized remnants reveal a pulsatory fashion of development, offering a unique window into modern-day volcanic processes.
Researchers from the University of Oxford have found evidence that Mars once had enormous magmatic systems deep beneath its surface, which could have produced complex crust and supported life. The discovery suggests that planets may not need plate tectonics to build habitable environments.
A Swiss-Italian team has discovered a vast magma reservoir containing approximately 6,000 km³ beneath Tuscany, which poses no threat to the region. The study uses ambient noise tomography to locate resources such as geothermal reservoirs, lithium, and rare earth elements.
A new study identifies phengite as a key carrier of halogens into the deep mantle, resolving a long-standing contradiction between shallow and deep halogen enrichment. Phengite transports fluorine and chlorine to depths of about 330 km, shedding light on diamond formation and Earth's chemical evolution.
The latest edition of Geysers: What They Are and How They Work offers fresh insights into the shifting activity and personalities of Yellowstone's iconic geysers. Readers will discover why some erupt with clockwork regularity while others slumber for decades before roaring back to life.
Researchers found that differences in tectonic plate thickness explain the extensive volcanism. Thinner lithosphere funneled hot plume material, causing uplift and volcanic activity. The study sheds light on global significance of the Iceland Plume.
A team of geophysicists from ETH Zurich and SUSTech, China, used computer models to simulate whether a completely liquid core could generate a stable magnetic field. Their simulations showed that the Earth's magnetic field was generated in the early history of the Earth in a similar way to today.
Scientists from the University of Göttingen have made a groundbreaking discovery, finding ruthenium in volcanic rocks on the islands of Hawaii. The finding suggests that material from the Earth's core is leaking into the mantle above, challenging previous assumptions about the planet's internal dynamics.
A team of geoscientists from Rice University and partners have discovered a sharp, volatile-rich cap just 3.8 kilometers beneath Yellowstone's surface. This cap helps trap pressure and heat below it, suggesting the Yellowstone magma reservoir is actively releasing gas while remaining in a stable state.
Glaciers within three miles of a volcano move 46% faster than average, according to a new study that analyzed velocity data from 85% of the world's glaciers. This increased melt reduces friction between the glacier and the underlying rock, resulting in faster glacier flow.
Researchers found that human-induced fluid fluxes in the deep subsurface are higher than natural rates, posing environmental impacts. The study highlights the need to manage the subsurface responsibly for a green transition and sustainable future.
Researchers from Tohoku University have developed a new signal processing technique that improves particle motion analysis in the time and frequency domain. This approach enables the detection and identification of various polarized seismic waveforms, including S-waves and P-waves, with improved accuracy.
Researchers found evidence of hydrothermal or metamorphic activity within the icy dwarf planets Eris and Makemake, which have methane deposits with geochemical origins. The discovery suggests elevated temperatures in their rocky cores, potentially leading to liquid water and habitability.
Decades of seismic data reveal that central Utah's earthquake 'swarms' are more common than other types of sequences, with 80% of sequences being swarms. The study also found that these swarms exhibit heterogeneous behavior across different locations in the region.
New research from Rice University suggests that ancient microorganisms helped cause massive volcanic events by facilitating the precipitation of minerals in banded iron formations. The study provides insight into processes that could produce habitable exoplanets and reframes scientists' understanding of Earth's early history.
Researchers at Stanford University found that deep subsurface microbial communities can change in a matter of days, driven by geological activity rather than environmental pressures. The study provides new insights into the complex dynamics of these underground ecosystems and opens up possibilities for mapping the deep subsurface.
Researchers at Mainz University found the Cumbre Vieja lava to be exceptionally low in viscosity, resulting in rapid flow and devastating damage. The study published in Nature Communications revealed that the lava's composition, particularly its silica content, contributed to its fluidity.
A 2017 Mw 5.4 Pohang earthquake in South Korea is believed to have been triggered by fluid injection at a nearby Enhanced Geothermal System (EGS) site, the largest-induced quake ever recorded at an EGS location.
