| Outline of Final Research Achievements |
The tsunami is a dreadful natural disaster that can give enormous damage to human society. In this research, we conducted a geomagnetic study that leads to their prevention / mitigation. We aimed to apply to the existing tsunami early warning system the fact that observable electromagnetic fields are generated by coupling of tsunami particle motions of the conductive seawater with the Earth's main magnetic field. As a result, the following two were proved probable by both actual observation and three-dimensional numerical simulation: (1) real-time transfer of seafloor electromagnetic data for tsunami early warning purpose, (2) improvement of the existing tsunami early warning system by adding information from the tsunami-generated electromagnetic fields.
