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.

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.

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.
