Research achievements

My research focuses on volcanic sedimentary systems and volcanic impacts and hazards on human activities in modern and ancient approaching from multidisciplinary views of sedimentology, volcanology, geomorphology, and geo-archaeology. Studied volcanic and river areas cover the active volcanoes in northeast Honshu, Kyushu, and Hokkaido in Japan, New Zealand, Philippines, and Italy. I am also interested in hydrological volcanic sediment transportation and deposition such lahars and volcanogenic floods and impacts of these phenomena on natural and human environments during eruptions and even after the eruptions. I have participated and led several projects relating to the recent eruptions at Mt Ruapehu 2007, New Zealand, Mt. Ontake 2014, and Mt. Kusatsu-Shirane 2018, Japan, where surface disturbance by eruptions and lahars have been observed.


Recent research activities

  • Hydrological volcaniclastic sedimentation (lahars) and assessments of associated volcanic hazards
  • Reconstruction of eruptive and lahar history
  • Sedimentology and geomorphology of catastrophic volcanogenic floods
  • Earth surface disturbance by eruptions and lahars: impacts and hazards on human activities in modern and ancient
  • Applications of ground penetrating radar (GPR) survey on volcanic areas
  • Volcano-snow/water interaction: hydrology at snow-clad volcanoes
  • Alluvial, fluvial, and lacustrine system evolution linked to volcanic processes
  • Caldera forming eruption aftermath
  • Submarine and sublacustrine eruptions: processes and mechanism
  • Distal volcaniclastic resedimentation and redistribution in non-marine/marine settings
