抄録

Broadband ocean bottom seismometers (BBOBSs) have been developed since 1990s and put into practice to explore the structure of the Earth’s interior beneath oceanic regions, e.g., mid-oceanic ridges, subduction zones, hotspots, and oceanic lithosphere-asthenosphere boundary. The BBOBSs have been used to investigate earthquake source process including slow earthquakes and oceanographical phenomena. The best way for the broadband seismic observation in the oceanic region seems that the borehole seismic observatory connected with the ocean floor cable, which is realized in several networks deployed close to the coast but it is rare even now. For scientific targets far away from the coast, we still need to develop and operate the autonomous system of BBOBS with better S/N for a temporary observation for focused scientific targets. In this review article, focusing mainly on achievements made in Japan, we describe a history of the development of BBOBS and some related instruments, scientific results based on observations with the BBOBSs, and future direction of broadband ocean bottom seismology.
