[H-DS10] Tsunami and tsunami forecast

Fri. May 30, 2025 1:45 PM - 3:15 PM 104 (International Conference Hall, Makuhari Messe)

convener:Toshitaka Baba(Graduate School of Science and Technology, Tokushima University), Hiroaki Tsushima(Meteorological Research Institute, Japan Meteorological Agency), Chairperson:Yusuke Yamanaka(Hokkaido University), Toshitaka Baba(Graduate School of Science and Technology, Tokushima University)

This session discusses issues related to improving real-time and long-term prediction accuracy of tsunami from earthquakes, landslides, and volcanoes, which include such as a better understanding of tsunami dynamics, new real-time tsunami observing systems deployed in the open ocean and coastal waters, methodologies of more rapid and accurate prediction during tsunami emergencies, more extensive and accurate inundation maps, and long-term tsunami potential forecast.
