| Abstract: | Based on the different working principles of SSQ-2I digital quartz pendulum (SSQ-2I pendulum) and VP vertical pendulum tiltmeter (VP vertical pendulum), we analyzed the continuity and integrality of observation data of these two sets of instruments in the Hailar Seismic Station from the year of 2018 to 2020. The annual drift and variation of inclination, the precision of data observation, the noise level, and the ability of earthquake reflection are also analyzed for comprehensive evaluation to the 2 sets of instruments efficiency. The results show that the performance of SSQ-2I horizontal pendulum is better than that of VP vertical pendulum. |
