| Abstract: | The YRY-4 four-component borehole strain gauge at Jiangning Seismic Station was installed in December 2006 and has accumulated a large amount of strain observation data over the years. Using Venedikov harmonic and relative calibration methods, the reliability of the borehole strain gauge at the station was checked from the aspects of the annual variation amplitude, continuity rate, and stability of the observation data. The results show that since 2009, the four-component borehole strain gauge at Jiangning Seismic Station worked stably and reliably, the observation data is continuous, and the recorded solid tide and seismic wave information are clear. |
