The report highlights the significant impact of seabed topographical changes resulting from the submarine uplift caused by the 2024 Noto Peninsula Earthquake. These changes have rendered certain fishing ports unusable and disrupted maritime transportation of relief supplies. The evolving marine environment, including not only shifts in seabed topography but also variations in the distribution of substances (such as salt, heat, chemical components, and marine lives) across different spatial and temporal scales, continuously affects people’s lives. To address this, various Japanese government agencies, including the Japan Coast Guard, Japan Meteorological Agency, and Fisheries Agency, regularly monitor and publicly disclose data related to salinity, water temperature, chemical concentrations, plankton abundance, and valuable fish resources. These agencies aggregate marine information under the comprehensive coordination of the Cabinet Office to create the “UmiShiru” (MDA Situational Indication Linkage, https://www.msil.go.jp/msil/htm/topwindow.html). While this centralized platform is groundbreaking in consolidating previously scattered marine information, the quality and quantity of available data remain insufficient. The current information provided by “UmiShiru” include seabed topography maps, tidal predictions at various locations, distribution of sea surface temperature, maps of surface ocean currents and surface waves, and tsunami simulation results. However, these resources primarily cater to experts, necessitating a certain level of knowledge for effective utilization. For the past few years, as a co-secretary of the Tsunami Disaster Prevention Study Subcommittee of the International Tsunami Disaster Prevention Society, the speaker has been working, on drafting the table of contents and making the editorial policy for the "Guidebook for the Planning of Tsunami Disaster Prevention Countermeasures by Local Residents" with the subcommittee members consisting of engineers, NPO executives, and others who are deeply interested in the. tsunami disaster prevention measures. In this talk, based on that experience, the speaker will discuss the present problems and future for creating and providing maps on the ocean environment and disaster prevention requested by society.
