About 7,300 years ago, Kikai produced the Kikai-Akahoya eruption, a giant event that released an estimated 133 to 183 cubic ...

Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the ...

Scientists have shed light on a thermal process in magma that may help explain why similar volcanic systems can produce very different eruptive behaviors. An international team, led by The University ...

The Methana volcano in Greece, thought to be dormant for hundreds of thousands of years, has been found accumulating enormous amounts of magma underneath. For more than 100,000 years, the volcano ...

How do volcanoes work? What happens beneath their surface? What causes the vibrations—known as tremor—that occur when magma or gases move upward through a volcano's conduits? Professor Dr. Miriam ...

Volcanoes can behave in strikingly different ways, even when they appear nearly identical. Some release slow, steady lava flows. Others erupt violently, sending ash and molten rock high into the sky.

A Martian volcano once thought to be the result of a single eruption turns out to have a much more complex past. Orbital imaging and mineral data show it developed through multiple eruptive phases, ...

Volcanologists discovered that really hot magma, oddly, won’t start cooling into rock until it reaches lower-than-normal temperatures. Reading time 3 minutes Rivers of lava rose to an average height ...

Volcanic eruption dynamics arise from the complex interplay between magma ascent, gas exsolution and the rheological properties of silicate melts. As magma rises through the crust, decompression ...
