Volcanology, Geology and petrology of volcanoes
Products of volcanic eruptions (pyroclasts and lavas) record complex physicochemical processes of magma ascent, ejection, and deposition. They are important clues to understand nature and dynamics of volcanic eruptions and resultant hazards. We are interested in physical and chemical parameters controlling eruption styles and their evolution, transport and sedimentation processes in volcanic plumes and flows, quantification of eruption phenomena using field data and models, and reconstruction of past eruptive events and disasters. We approach based on field survey, laboratory work, image/numerical analysis, etc. Not only recent eruptions but also large-scale caldera-forming eruptions that can cause significant impacts on human and environment are also our interests.
