Pyroclastic density currents associated with the 2015 phreatomagmatic eruption of the Kuchinoerabujima volcano

Though "low-temperature pyroclastic flow" is frequently observed with phreatic eruptions, there are few descriptions of its internal environment. The low-temperature pyroclastic flow of the 2015 eruption of Kuchinoerabujima volcano, southwestern Japan, provides geophysical data, video image, and geological descriptions of the deposits. The video image indicates that the velocity of flow exceeded 42 m/s. The dieback of the vegetation and deformation of some plastic materials in the flow, with absence… Read more
