Cover Story: Hydrovolcanism is a type of volcanism where magma and water interact either explosively or non-explosively. Hydrovolcanism is commonly used as a synonym for phreatomagmatism. However, recently, phreatomagmatism has appeared more in association with volcanism that occurs in shallow subaqueous or terrestrial settings. Here, a revised and reviewed classification scheme is suggested for hydrovolcanism with special reference to its explosive varieties, based on their geo-environment in which magma–water interaction takes place and explosivity plus mode of energy transfer are required to generate kinetic energy to produce pyroclasts. Explosive hydrovolcanism is discussed here from a field context, from the perspective of monogenetic volcanism. View this paper
