Abstract :
It is essential to observe seismic activities on the sea floor just above the seismogenic zones where large earthquakes have been occurred. We have developed UT-OBCS, a new ocean bottom cabled seismometer for a high density seismic array network, with utilizing ICT (Information and Communication Technologies), i.e., IP (Internet Protocol) on the seafloor. UT-OBCS is a compact and low cost system. The system reliability is kept by a redundant transmission route design which is easily constructed using the ITC. In 2010, we started a real time seismic observation in the Sea of Japan by using four UT-OBCSs and a 25 km cable.
