Scientists working alongside the U.S. Coast Guard have discovered a 1,640-foot-tall (500 meters) structure that looks like an underwater volcano off the coast of Alaska. The structure may be spewing ...

Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.

Mexico’s Popocatépetl volcano has long drawn attention for its size, constant activity, and glowing plumes of smoke and ash, yet for decades scientists did not fully understand what was happening deep ...

A team from UNIGE and INGV has represented in 3D, with unprecedented precision, the internal structure of an active volcanic system. An advance for risk management. Volcanic eruptions can have ...

Colossal volcanic eruptions like the kind that may have obliterated the dinosaurs more than 65 million years ago are caused by mantle plumes that rise from shifting underground mountains deep within ...

Researchers from the National Oceanic and Atmospheric Administration Ship Fairweather and the University of New Hampshire analyze mapping data in the U.S. Coast Guard Cutter Healy’s computer lab while ...

A group of researchers from the University of Trento discovered what seems to be an important part of Venus' volcanic history. It was confirmed that an underground lava tube has existed beneath the ...
