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.
An international assessment report has been released to provide definitive statements on the atmospheric impacts from a huge volcanic eruption in 2022.

Located on the island of Sicily, in Italy, Mount Etna is one of the world's most active volcanoes. Documentation of its many eruptions stretches back as far as 2,700 years ago, with the most recent occurring in June 2025. ...
Mount Lewotobi Laki Laki, one of Indonesia's most active volcanoes, erupted for a second straight day Wednesday, spewing towering columns of hot ash that later blanketed villages. No casualties were immediately reported.
