Abstract

A project of submarine cabled seafloor observatory network development has been carried out in Japan since 2006. This research has aimed to establish the technology of a large scale real-time seafloor research infrastructure development for earthquake, geodetic and tsunami observation. The project scheduled to install 20 sets of cabled earthquake and tsunami observatory to an active seismogenic zone with mega-thrust earthquakes called Nankai trough. This paper describes design concept of a novel ocean observation system and the key technologies for reliable and extendable real-time seafloor monitoring.
