Abstract
An ocean bottom cable system (OBCS) is the best solution for monitoring the tectonic activities in a seismogenic zone. However the number of seismometers of the existing OBCS is insufficient for high resolution observation of the seismogenic zone, because the cost of the OBCS has been very expensive. In order to solve this problem, the authors have studied new cost effective OBCSs with 40 seismic arrays which determine the location of seismic events over a 100 square kilometer area for long-term observation in a remarkable seismogenic zone based on the cost analysis of existing OBCS.
