Anomaly analysis of strain observation at Huichang Seismic Station in July 2018
摘要
Abstract
From July 13 to 20,2018,the observation of the cave strain measurement item at the Huichang Seismic Station,that is,the NS component of the SS-Y type extensometer instrument,showed a trend turn and a tensile rise change,with the maximum amplitude of about 9.7×10-7(equivalent to 35 times the diurnal variation amplitude),which was significantly different from the annual low point of the station in early June.From the observation system,meteorological factors,environmental interference,and other aspects,combined with other measurements of the station to carry out a comparative analysis,it is concluded that the anomaly may be caused by the superposition of two environmental interference anomalies from different sources,which can exclude the influence of crustal tectonic movement and the possibility of seismic geophysical anomalies are small.关键词
