Abstract：The paper analyzes the ground deformation observed by the quartz horizontal pendulum tiltmeter at Tengchong seismic station before the moderate and strong earthquakes in west Yunnan in recent years. The paper focuses on the study of the features of the short-impending precursors of the ground deformation before these earthquakes. The results show that the ground deformation obviously show anomaly, which is helpful for determining the short-impending anomaly characteristicsfor the earthquake prediction.
Keywords：Quartz horizontal pendulum tiltmeter at Tengchong seismic stationModerate and strong earthquakesThe short-impending anomaly characteristics
