摘要
对2000年元月1日至2003年4月30日间的体应变和差应变分钟值曲线图进行了统计,落实了220个有同震应变变化的地震。得知观测到应变波动的最大震中距是25467km,最小震级为ML2.9,进而对两套钻孔应变仪对地震波动的记录能力作了统计。
We have made statistical analysis of difference minute figure of volume strain and shear strain from January 1,2001 to April 30,2003 and found 220 co-seismic strain step. The largest epicentral distance was 254 687. 36 km, the minimal earthquake magnitude is M 2. 9 in co-seismic change which can be observed. Further more, we have analyzed the response capability of earthquake for our two borehole volume strain.
