- Abstract:
- According to Earthquake Cases in China and summary report on some earthquakes,we count the deformation anomaly of MS≥5.0 earthquakes from 1966 to 2018 in North China. Based on the seismic correspondence and anomaly reliability of deformation stations and items,we analyze the sensitivity of deformation stations and items in North China. Then we obtained the sensitivity of items in four sub-sreas which were divided from the study area. Finally,the relationship between sensitive stations and their tectonic locations was analyzed. The results show that the sensitivity of some deformation stations is relatively high,includes Taiyuan,Zhangjiakou,and Yixian stations etc.,which mainly distributed in the west segment of Zhangjiakou-Bohai seismic active belt and the north segment of Tancheng-Lujiang seismic zone. The sensitivity of horizontal pendulum are higher in each sub-area,the sensitivity of water tube tiltmeter is higher in Shanxi seismic zone,the sensitivity of body strain is higher in Zhangjiakou-Bohai seismic active belt and south segment of Tancheng-Lujiang seismic zone,the sensitivity of extensometer is higher in north segment of Tancheng-Lujiang seismic zone. The sensitivity of the stations near the hanging wall of normal fault and the footwall of reverse fault is relatively high.
