Scientists Discovered a 'Yellow Brick Road' at The Bottom of The Ocean An expedition to a deep-sea ridge, just north of the Hawaiian Islands, revealed a surprise back in 2022: an ancient dried-up lakebed paved with what appears to be a yellow brick road.

One of Earth's Most Explosive Volcanoes Is Quietly Refilling With Magma About 7,300 years ago, a volcano off Japan's Kyushu island unleashed what remains the largest known eruption of the Holocene, our current geological epoch.

The Mediterranean Isn’t Safe: Scientists Warn of Inevitable Tsunami Contrary to common belief, the Mediterranean holds a significant and underrecognized tsunami risk, with waves capable of striking coastlines in minutes. The Mediterranean Sea is often dismissed as a low-risk zone for tsunamis, but that assumption is increasingly being challenged. Historical recor

Mars' 'young' volcanoes prove more complex than scientists once thought What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of time. To fully u...

Mars’ young volcanoes show multi-phase magma flows, revealing complex #FluidDynamics beneath Pavonis Mons.
Studying these planetary flows can inform models of heat and phase transfer in extreme environments.
