Scientists Discover Enormous Hole in Indian Ocean

Scientists have uncovered new insights into the Indian Ocean Geoid Low, the largest gravity hole on Earth, linking it to mantle processes such as sinking slabs and rising plumes originating from deep within Earth's mantle, which have evolved over millions of years and are influenced by interactions with the African hotspot and mantle structures like the LLSVP.

AI Reveals Hidden Earthquake Activity and Risks in Yellowstone

Researchers have used AI and machine learning to identify ten times more earthquakes in Yellowstone from 2008 to 2022 than previously recorded, revealing over 86,000 seismic events and providing new insights into volcanic and seismic activity, especially earthquake swarms along immature faults, which can improve safety and energy development strategies.

Hidden Mantle Plume Detected Beneath Oman Could Explain India's Movement

Scientists have identified a 'ghost' mantle plume beneath Oman, a hot rock column with no surface volcanic activity, which could reshape understanding of Earth's internal heat flow and geological processes. The discovery, based on seismic data and computer modeling, suggests the existence of similar hidden plumes worldwide, potentially impacting models of Earth's thermal evolution.

Unveiling the North Sea's Hidden Glacial Landscapes

Researchers have discovered well-preserved glacial landforms buried beneath the North Sea, using seismic data to reveal features from about 1 million years ago. These findings, published in Science Advances, highlight how past ice sheets responded to climate changes during the Mid-Pleistocene Transition, offering insights into current climate change impacts. The study utilized 3D seismic technology, originally developed for oil and gas exploration, to map these ancient landscapes, which include features carved by ice sheets and ocean currents, reshaping our understanding of the North Sea's glacial history.

Earth's Inner Core Rotation Slows, Impacting Day Length

Researchers from the University of Southern California have found that Earth's inner core has been slowing down since around 2010, altering the length of days by fractions of a second. This slowdown is attributed to convection within the liquid iron outer core and gravitational forces in the mantle. The findings, based on seismic data from earthquakes and nuclear tests, were published in the journal Nature.

"Debunked: 'Alien' Signals Revealed as Earthly Origins"

A new paper challenges Harvard astrophysicist Avi Loeb's claim that a 2014 meteorite came from outside our solar system, suggesting that the seismic signals detected were actually caused by a truck. The study, presented at the Lunar and Planetary Science Conference, disputes Loeb's conclusions and proposes that the debris collected from the ocean floor is likely from unrelated meteors. Despite criticism, Loeb defends his findings, pointing to other data and chemical compositions in the particles.
