A massive, iron-rich structure sitting at the base of Earth’s mantle beneath the Hawaiian Islands may be doing more than scientists previously understood to fuel the archipelago’s volcanic activity.

When tens of thousands of earthquakes shook Santorini, the cause wasn’t just shifting tectonic plates—it was rising magma. Scientists tracked about 300 million cubic meters of molten rock pushing up ...

What may look like a single volcanic eruption is usually the visible outcome of far more complicated activity taking place underground. Beneath the surface, magma can migrate, cool, mix, and ...

A huge river of underground magma responsible for the recent eruptions at Iceland's Reykjanes peninsula flowed much faster than scientists initially thought. The 9-mile-long magma dike, as the ...

Scientists are planning to drill into an Iceland volcano in the hunt for near-unlimited energy. The project, helmed by the Krafla Magma Testbed (KMT) organization, is set to start drilling into a ...

In volcanoes, fluid inclusions are dominantly composed of CO 2. At magmatic temperatures (1200˚ C or 2192˚ F), the density of the CO 2 strongly depends on pressure, which is influenced by the depth of ...

Scientists in Iceland have come up with an ambitious plan to drill into a volcano's magma chamber to source an abundant amount of clean, super-hot geothermal energy. The project, which would be a ...
