An ocean bottom cable seismometers system (OBCS) is the best instrument to observe seismic activities on the sea floor because data is obtained in real-time. Therefore some systems have been installed over the past 25 years around Japan. Although the existing OBCS systems are useful for the study of seismic activities, the number of station is limited due to their costs. In order to lower the cost...
An ocean bottom cabled seismometer (OBCS) is the best solution for the monitoring of earthquake activity in a seismogenic zone where big or huge earthquakes have occurred repeatedly. However, the number of existing OBCS has been insufficient for high resolution observation of the seismogenic zone, due to the high costs involved. In order to lower the cost of OBCS and to meet requirements for flexibility...
