The Seismology and Volcanology Research Department is composed of four research laboratories with a total of nineteen researchers pursuing the study of the mechanisms behind earthquake generation, prediction of disastrous interplate earthquakes (especially the Tokai, Tonankai and Nankai earthquakes), prediction of volcanic eruptions, machinery, tools and systems to be used in the observation of earthquakes and volcanic activity, and the generation and propagation of Tsunami waves and estimation of their height in coastal regions. Since the beginning of the National Program of Earthquake Prediction and Prediction of Volcanic Eruption, our findings have contributed greatly to JMA's monitoring of seismic and volcanic activity.
