Arc volcano releases mix of material from Earth’s mantle and crust

black rock and green rock

Rock from a common type of volcano shows surprising evidence of the descending tectonic plate. Analyses show that magnesium atoms are somehow drawn out of the crust, deep below the surface.

Simulating path of ‘magma mush’ inside an active volcano

The first simulation of the individual crystals in volcanic mush, a mix of liquid magma and solid crystals, shows the mixing to help understand pressure buildup deep inside a volcano.

Scientists ready to study magma formation beneath Mount St. Helens

Mount St. Helens as it appeared two years after its catastrophic eruption on May 18, 1980.

Scientists are embarking on research to improve volcanic eruption forecasting by learning more about how a deep-underground feeder system creates and supplies magma to Mount St. Helens.

Some volcanoes ‘scream’ at ever-higher pitches until they blow their tops

Redoubt Volcano's active lava dome as it appeared on May 8, 2009.

Swarms of small earthquakes before a volcanic eruption can come in such rapid succession that they create a signal called harmonic tremor. A new eruption analysis from Alaska’s Redoubt Volcano shows the harmonic tremor glided to higher frequencies, then stopped abruptly just before six eruptions in 2009.

Russian Far East holds seismic hazards that could threaten Pacific Basin

The 2009 eruption of Sarychev Peak in the Kuril Islands.

The Kamchatka Peninsula and Kuril Islands, long shrouded in secrecy by the Soviet government, are a seismic and volcanic hotbed with a potential to trigger tsunamis that pose a risk to the rest of the Pacific Basin.
