云县地震台DSQ水管倾斜仪与VP垂直摆观测资料对比分析
Comparative analysis of observation data between DSQ water-tube tiltermeter and VP vertical pendulum tiltermeter at Yunxian Seismic Station
摘要
Abstract
Both DSQ water-tube tiltermeter and VP vertical pendulum tiltermeter installed at Yunxian Seismic Station are digital instruments for tilt observation, with same physical measurement, but different structures and principles. We analyzed contrastively the integrity rate, inherent accuracy, annual variation, correlation and morphological characteristics of data recorded.The results show that the DSQ water-tube tiltermeter and VP vertical pendulum tiltermeter are stable, the data recorded are complete, the change characteristics of two sets of tiltermeters are consistent. They can reflect well the change characteristics of the tilt in the observation region and the obvious influence of rainfall on annual variation trend of recordsl.关键词
