摘要
介绍了泉州地震台TJ-ⅡC钻孔应变仪的概况,对观测资料质量进行简单的分析。利用观测资料分钟值,对2002～2010年发生在中国台湾地区与印尼苏门答腊及附近区域强震记录特征进行了统计分析,研究了记录地震应变波的震级与震中距、记录到时差、记录振幅等有关问题,通过对记录到的震前应力异常变化的相关分析,寻求其映震能力的有关结果。
This paper introduces TJ-Ⅱ analyses the quality of its observation C borehole strainmeter at Quanzhou seismic station and data. Based on the minute-value observation data, we conduct a statistical analysis of strong motion records of Taiwan and Indonesian Sumatra and its adjacent area from 2002 to 2010. And investigate parameters such as magnitude of seismic strain wave, epicentral distance, arrival time difference and amplitude. By analyzing seismic stress changes before earthquakes, earthquake-reflecting ability of the borehole strainmeter is represented.
