Working Paper PUEAA No. 6. Recent seafloor seismic and tsunami observation systems for scientific research and disaster mitigation

Due to its position between various tectonic plates, Japan is at constant risk of natural disasters such as volcanic eruptions, earthquakes, and tsunamis. The latter have a great and destructive impact since a large part of the Japanese population lives on coastal plains. The importance of having early warning systems has led Japanese scientists to give particular importance to the study of the seabed and its tectonic characteristics, in order to better understand its geological composition, and to be able to create better and faster early warning systems with new technologies for transmission and data collection.
