利用近场数字强震资料重新定位伽师、乌恰4次中强地震
|
摘要
利用近场数字强震记录资料,采用和达法、台网地震编目程序(BLOC86)分别对新疆乌恰、伽师地区4次中强地震进行了重新定位。通过对定位结果的对比分析,结合新疆台网的部分实际工作,认为充分利用近场数字强震资料参与定位对于提高、总结和研究新疆部分地区地震定位精度是很有必要的。
The digital strong motion records in near field were used to relocate four moderately strong earthquakes in Wuqia and Jiashi area by Wadati line,network seismological catalogue program.Combined with some practical work in Xinjiang network,the contrastive analysis of location result showed that using the digital strong motion records in near field to locate was very necessary to improve,summarize and research the earthquake location accuracy in some places of Xinjiang.
