Researchers discovered that bridgmanite deep in the mantle can store far more water at high temperatures than previously believed. During Earth’s cooling, this hidden reservoir could have held water volumes comparable to today’s oceans. Over time, that buried water helped drive geology and rebuild the planet’s surface environment.

These ancient scars not only shaped the landscape but still influence earthquakes and could point to untapped geothermal energy. Sun, 07 Sep 2025 16:53:33 EDT https://www.sciencedaily.com/releases/2025/09/250907024546.htm https://www.sciencedaily.com/releases/2025/08/250809100910.htm Deep beneath the Antarctic seas lies a hidden network of 332 colossal submarine canyons, some plunging over 4,000 meters, revealed in unprecedented detail by new high-resolution mapping. These underwater valleys, shaped by glacial forces and powerful sediment flows, play a vital role in transporting nutrients, driving ocean currents, and influencing global climate. Striking differences between East and West Antarctica’s canyon systems offer clues to the continent’s ancient ice history, while also exposing vulnerabilities as warm waters carve away at protective ice shelves.

A new study by University of Hawai‘i researchers shows that even under conservative climate scenarios, nearshore waters will change more drastically than reefs have experienced in thousands of years. Some coral species may adapt, offering a glimmer of hope, but others may face critical stress. Wed, 16 Jul 2025 23:51:08 EDT https://www.sciencedaily.com/releases/2025/07/250716000851.htm https://www.sciencedaily.com/releases/2025/07/250708045654.htm As glaciers melt around the world, long-dormant volcanoes may be waking up beneath the ice. New research reveals that massive ice sheets have suppressed eruptions for thousands of years, building up underground pressure. But as that icy weight disappears, it may trigger a wave of explosive eruptions—especially in places like Antarctica. This unexpected volcanic threat not only poses regional risks but could also accelerate climate change in a dangerous feedback loop. The Earth’s hidden fire may be closer to the surface than we thought. Tue, 08 Jul 2025 12:59:23 EDT https://www.sciencedaily.com/releases/2025/07/250708045654.htm https://www.sciencedaily.com/releases/2025/06/250627095035.htm Beneath the Afar region in Ethiopia, scientists have discovered pulsing waves of molten rock rising from deep within the Earth — a geological heartbeat that could eventually split Africa in two. These rhythmic surges of mantle material are helping to stretch and thin the continent’s crust, setting the stage for a new ocean to form in millions of years. The pulses aren’t random: they follow patterns shaped by the tectonic plates above, behaving differently depending on how thick the plates are and how fast they’re spreading.

Channeling water runoff or lowering groundwater levels could reduce risks for surrounding communities. Fri, 02 May 2025 18:25:09 EDT https://www.sciencedaily.com/releases/2025/05/250502182509.htm https://www.sciencedaily.com/releases/2025/05/250501122438.htm A new study has investigated the use of a new monitoring technique for early warning of a volcanic eruption. The research team compared the earthquake signals during two eruptions of Ontake Volcano in Japan, one of which was a small eruption and the other of which was explosive. From this, they were able to identify that shear-wave splitting parameters showed differences depending on the size of the eruption. The study proposes that the monitoring of this signal would provide a useful early warning of dangerous volcanic eruptions.

The rocks will help unravel the mantle's role in the origins of life on Earth, the volcanic activity generated when it melts, and how it drives the global cycles of important elements such as carbon and hydrogen.

Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.

The findings hone scientists' understanding of Earth's earliest geologic processes, and they provide new evidence in a decades-long scientific debate about the geologic history of Earth. Specifically, the results provide evidence that the oxidation state of the vast majority of Earth's mantle has remained stable through geologic time and has not undergone major transitions, contrary to what has been suggested previously by other researchers.

Under an hour's drive from the country's capital city, the ongoing eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.

The explosions were driven by sudden pressure increases as the ground collapsed, which blasted plumes of rock fragments and hot gas into the air, much like a classic stomp-rocket toy.
