Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

"This has profound implications for how we interpret surface volcanism, earthquake activity and the process of continental ...

Deep within the Earth’s mantle, rhythmic pulses of hot lava are emerging on the surface, offering a rare glimpse into the ...

Scientists found a rhythmic mantle plume beneath Ethiopia is slowly tearing Africa apart - hinting at the birth of a new ...

Explore the Pacific Ring of Fire, a seismically active region around the Pacific Ocean known for earthquakes and volcanoes.

I just returned home from an adventure in Ecuador, the highlight was two weeks on a boat exploring the Galápagos Islands. As an earth scientist, there’s always a geologic story wherever I visit, but ...

A study in Geology presents evidence that subduction can spread like a contagion, jumping from one oceanic plate to another — a hypothesis previously difficult to prove.

Ocean acidity levels became intolerable and led to more than half of all marine life dying out. 66 million years later, it’s happening again. This time, there is no asteroid—just us humans.

A new assessment finds that the world’s oceans crossed the safe threshold for acidification in 2020, breaching a key planetary boundary and posing serious threats to marine life. Ocean ...

Another is ocean acidification, also caused by burning fossil fuels. In 2023, researchers determined that six of these boundaries had already been crossed. The new research adds a worrying seventh.

Researchers said in 2023 that 6 of the 9 boundaries—biogeochemical flows, biosphere integrity, the climate, freshwater, land use, and novel entities—had been crossed. Last year, they issued a "red ...
