Abstract
In this paper,combined with the water tube and the extensometer observation data of Tieling Seismic Station,the January 23,2013 Dengta MS 5.1 earthquake and April 22,2013,Tongliao MS 5.3 earthquake are analyzed comprehensively. According to the study,it is found that before the two earthquakes the data showed precursory anomalies. The trend anomaly of the water tube tiltmeter data and the extensometer data are as break the annua1 variation. The short-term anomaly of the water tube tiltmeter data appeared as high frequency jitter and shape distortion of the diurnal variation in the days before the two earthquakes.In addition,the abnormalities and the morphological characteristic before the earthquakes are obvious.关键词
