海底电缆系统(OBCS)是监测孕震带构造活动的最佳解决方案。然而，现有OBCS的地震仪数量不足以对孕震带进行高分辨率观测，因为OBCS的成本非常昂贵。为了解决这一问题，作者在对现有OBC进行成本分析的基础上，研究了新的具有成本效益的OBCS，它由40个地震台阵组成，可以确定100平方公里范围内地震事件的位置，以便在显著的孕震区进行长期观测。
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.
