Volcanoes as a research area encompasses the multidisciplinary scientific study of magmatic systems, eruption dynamics, and associated surface and atmospheric processes. It integrates petrology, geochemistry, geophysics, and fluid dynamics to characterize magma generation, ascent, storage, and degassing, as well as the mechanical behavior of volcanic edifices. Research addresses eruption forecasting through monitoring of seismicity, ground deformation, gas emissions, and thermal anomalies, and develops quantitative models of eruption columns, pyroclastic flows, lava emplacement, and lahar generation. The field also investigates volcanic contributions to crustal evolution, volatile cycling, and climate forcing, and underpins probabilistic hazard assessment and risk mitigation methodologies.
Samples of extremely small crystal clots, each polished to the thickness of a human hair or thinner, have revealed information about the process triggering the major 2006 eruption of Alaska's Augustine Volcano.

A small international team of volcanologists has built a more detailed picture of the Campi Flegrei caldera's internal structure using high-resolution seismic imaging and results from rock physics experiments conducted on ...
When a volcano erupts, it can spew ash high into the atmosphere—inserting aerosols right where clouds typically form. How exactly these aerosols impact cloud formation has long been a mystery to atmospheric scientists.
