| Outline of Final Research Achievements |
Towards the mitigation of tsunami disaster, we developed a new type of ocean bottom tsunami meter called Vector TsunaMeter (VTM), which consists of the Ocean Bottom Electro-Magnetometer (OBEM) and the Deep-sea Differential Pressure Gauge(DPG), and can estimate the tsunami propagation vector as well as the tsunami height based on the ocean dynamo effect. By using the VTM, we build a real-time tsunami monitoring system, in which data collected by the VTM is transmitted acoustically to the Wave Glider (WG), an autonomous ocean-going platform, on the ocean surface, and then transferred to the shore over satellite. We deployed the system off the pacific coast of the Tohoku area, and successfully detected the tsunami signal generated by the 2014 Chile earthquake.
