The video provides a short introduction to magmatic volatiles and the basic chemical and petrological factors that control their solubility. Besides the two most common volatile species, water and carbon dioxide, the video discusses noble gases, sulfur, and chlorine. The viewer is introduced to solubility plots, basic terminology, Henry’s Law, distribution coefficients, and other ideas that allow one to understand the role of temperature, pressure, and magma composition on volatile solubility. Solubility is considered relative to saturation with gas, liquids (e.g., some sulfides), and crystals. The tutorial also seeks to place the systematics of volatile solubility in the context of volcano monitoring and outgassing.
This eVolcano lecture on pyroclastic fall deposits is given by Samantha Engwell (British Geological Survey) and Julia Eychenne (Laboratoire Magmas et Volcans, France). It provides insights into the sedimentary and textural characteristics of tephra fall deposits, from the outcrop scale…

Explosive volcanic eruptions can perturb the hydrology of landscapes downwind and downstream of volcanoes by damaging vegetation and depositing large amounts of volcaniclastic sediment. Fluxes of water and sediment from volcanically perturbed landscapes can increase substantially, prompting hazardous geomorphic responses…
