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 ...

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 volcanoes are notoriously dangerous and unpredictable. But did they behave differently when they were young? Here, pre-eruptive magmatic processes and timescales of a rare, young ...

Here in western Montana, we are used to preparing for severe weather and winter storms, but there is another natural threat ...

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 ...

Over recent years there has been a paradigm shift in understanding how magma is stored and the processes that mobilise magma and enable it to erupt. Advances in microanalytical techniques have ...

(photoz/Canva) 'Extinct' volcanoes that haven't erupted for tens of thousands of years may not actually be inactive, but silently accumulating huge reservoirs of magma to fuel future outbursts. This ...

The last eruption of Greece’s Methana volcano was around 250 B.C.E. Ever since that event, which was recorded by the Greek historian Strabo, the mountain has lurked silently, just across the Saronic ...
