摘要
对比分析 VP、SSQ 秒采样倾斜仪及 JCZ-1T 测震仪在同震时段的响应特征和震相参数,三者能记录到清晰的 P 波、S 波和面波,VP 和 JCZ-1T 记录到的 S波比 SSQ 清晰。VP 记录的地震波频带宽度和 JCZ-1T 记录的较一致。2013年4月16日伊朗、巴基斯坦交界地区 M7.7地震前, JCZ-1T 地震仪、SSQ 倾斜仪同时记录到周期为15~30s 的缓慢运动事件。
By comparing the response characteristics and seismic phase parameters recorded by VP,SSQ second sampling tiltmeter and JCZ-1T seismometer in the same period of the earth-quake,this paper presents that the three instruments can all record clear P wave,S wave and surface wave,and S wave recorded by VP and JCZ- 1T is clearer than that recorded by SSQ. Bandwidth of seismic waves recorded by VP is more consistent with that of JCZ-1T records.Be-fore the Iran and Pakistan boundary M 7.7 earthquake on April 1 6,2013,JCZ-1T seismometer and SSQ tiltmeter simultaneously record a slowly moving event at intervals of 15~30 s.
