| 摘 要： | 采用十五期间架设的贵阳、昭通、永胜和腾冲四个台的钻孔应变资料,对2015年4月25日尼泊尔Ms8.1地震同震应变波进行对比分析,结果表明非同台钻孔应变同震记录的初动时间、波动幅度和持续时间等与地震震级、震中距存在一定的关系,但在地震应变阶、张压性变化等方面差异较大,造成此差异的原因尚需进一步研究。

BOREHOLE STRAIN CO-SEISMIC RECORDS ANALYSIS ON Ms8.1 EARTHQUAKE IN NEPAL |
| |
| Abstract: | Using the drilling strain data collected in Guiyang, Zhaotong, Yongsheng and Tengchong seismic stations built during the 10th five-year-plan, we analyze the Co-seismic strain waves from Ms8.1 earthquake in Nepal in April 25,2015. Results show that the initial wave time, fluctuation amplitude and duration of different stations’ borehole strain records have certain relationships with the magnitude, epicenter distance. However, there are great differences in terms of seismic strain and tension and the reasons for these differences need further research. |
