摘要

应用安丘台跨断层定点形变的水准观测资料进行一般多项式曲线分段拟合,结合周边的地震活动背景,研究断层活动与地震活动之间的关系,结果表明,断层活动和周边的地震活动在频度上存在对应关系。可利用断层活动与地震活动的对应关系,为台站周边地区的地震预报提供参考指标。
Using the universal polynomial piecewise curve fitting method to analyze the across- fault fixed point deformation leveling data recorded at Anqiu station, and considering the seismicity background of the periphery region, the fault movement and its relationship with earthquake activity are studied. The result shows that the method is more liable to monitor the statuses of fault movements and earthquake activities. There is a certain relationship between the measured cross-fault displacement and earthquake activity. According to the relationship between the observation data and seismic activity, a reference index can be given for earthquake prediction near the station region.
