The combination of the piston-cylinder press and heating assembly allows for experiments that can attain the very high pressures and temperatures found under volcanoes. News media use of the ...

Focus: Modelling the eruptive behaviour of Popocatépetl volcano to understand relationships between the timescales of pre-eruptive magmatic processes and the dynamics of Popocatépetl’s plumbing system ...

Long-quiet volcanoes in the Cascades region of the Pacific Northwest are still underpinned by large reservoirs of magma, new research finds. The findings have implications for monitoring volcanoes ...

Scientists are predicting that a mile-deep volcano off the U.S. West Coast will erupt this year. The Axial Seamount, an ...
