Volcanology is the scientific discipline devoted to the study of volcanoes, magmatic processes, and related phenomena such as eruptions, fumarolic activity, and volcanic gas emissions. It integrates petrology, geochemistry, geophysics, and tectonics to investigate magma generation, ascent, storage, and eruption dynamics within the lithosphere and asthenosphere. Volcanologists analyze rock, ash, and gas compositions, monitor seismicity, ground deformation, and thermal anomalies, and develop physical and numerical models to understand eruptive behavior and conduit processes. The field also characterizes volcanic hazards, eruption forecasting methodologies, and long-term magmatic fluxes, contributing to broader insights into planetary differentiation, crustal evolution, and volatile cycles on Earth and other terrestrial bodies.
Io is a world of extremes. It is by far the most volcanically active world in our solar system. Being continually squeezed in the never-ending tug-of-war between Jupiter and its larger satellites will do that to a moon. As ...

For more than 100,000 years, the Methana volcano in Greece appeared dormant. No lava, no explosions, no ash clouds. It appeared extinct, like many other volcanoes today. An international research team led by ETH Zurich has ...

A lot of research goes into determining how to best predict the next eruption of the Yellowstone supervolcano. Part of this involves pinning down how the magma migration system functions and evolves over time. The exact mechanism ...
Supereruptions are extremely large volcanic eruptions that eject more than 1,000 cubic kilometers of magma, rock and ash. They are among the most hazardous geological events on Earth and have profound impacts on the environment, ...
