NASA's Juno spacecraft has discovered a giant volcanic hot spot on the surface of Jupiter's hellish moon Io. The eruptions in ...

With eruptions in 1998, 2011, and 2015, the volcano serves as a perfect laboratory, and experts expect an eruption by the end ...

It appears that these magma bodies exist beneath volcanoes over their whole lifetime, not just during an active state.' ...

Unlike old soldiers, old volcanoes seemingly don't even fade away, much less die, with researchers discovering magma chambers ...

It has been in a lethargic state for 4,800 years and new data is helping geologists to better assess possible eruptions ...

For decades, scientists believed that magma chambers beneath volcanoes were transient, forming before an eruption and then ...

Unlike the Pacific Northwest’s steep-sloped Cascade volcanoes such as Mount St. Helens or Mount Hood that tend to explode when they erupt, Axial Seamount’s magma forces its way out as fluid ...

Unlike the Pacific Northwest’s steep-sloped Cascade volcanoes such as Mount St. Helens or Mount Hood that tend to explode when they erupt, Axial Seamount’s magma forces its way out as fluid ...

Researchers used seismic waves to identify magma chambers beneath the surface of six volcanoes of various sizes and dormancy within the Cascade Range, which includes half of the U.S. volcanoes ...

A seismic survey challenges the long-standing belief that only active volcanoes have large magma bodies sitting beneath them.

Iezzi's team with the USGS Cascades Volcano Observatory monitors the Cascades daily. Their infrasound and seismic sensors detect cracks and movement from below as magma is forced upward.

While Hawaii is formed by volcanoes, including the highly active Mt. Kilauea, I want to explore an easier-to-reach region: ...
