[H-DS10] Tsunami and tsunami forecast

Wed. May 25, 2022 10:45 AM - 12:15 PM 202 (International Conference Hall, Makuhari Messe)

convener:Satoko Murotani(National Museum of Nature and Science), convener:Hiroaki Tsushima(Meteorological Research Institute, Japan Meteorological Agency), Chairperson:Naotaka YAMAMOTO CHIKASADA(National Research Institute for Earth Science and Disaster Resilience), Hiroaki Tsushima(Meteorological Research Institute, Japan Meteorological Agency)

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.
