Since 2017,we have upgraded the data collectors in the ten borehole strain stations,it has produced a large number of strain observation data from high sampling boreholes. Using the correlation coefficient and self-check accuracy of the two inspection four component observational data self-consistent performance indicators,we have quantitatively analyzed these stations of strain seismic waves recorded on February 3,2020 in Chengdu M5.1 earthquake and the Kuril islands M7.5 earthquake on March 25,2020. The result shows that reliability of these high sampling observation data is high. In addition,by analyzing the seismic phase of two earthquakes recorded by the ten borehole strain stations,it proved that the four component borehole strain meter high samples have the ability to record clear strain seismic wave,and its reliability is high. Comprehensive results show that high sampling four component borehole strain meter can be further provides new data for the seismological research resources.
