The 1980 eruption cycle made Mount St. Helens one of the most famous and now best-monitored volcanoes in the Cascades. But it is far from the only volcano in the range. From southern British Columbia ...

Methana volcano looked dead for more than 100,000 years, yet magma kept building below ground. By dating tiny crystals, ...

Earth's "gold kitchen" lies deep beneath the seafloor. Island arcs, whose volcanoes form above subduction zones where one oceanic plate sinks beneath another, are often particularly rich in gold. The ...

Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Subduction zones host some of the most dynamic volcanic systems on Earth, driven by the descent of an oceanic plate beneath a continental or another oceanic plate. Fluid release from the downgoing ...

Subduction zone volcanism is driven by the descent of oceanic lithosphere into the mantle, where increasing pressure and temperature liberate volatiles that flux the overlying mantle wedge and induce ...
