Abstract
Based on the coseismic response recorded by the water level of Shilin well in Yunnan Province in the past six years,this paper analyzed the characteristics and mechanism of the coseismic response of Shilin observation well in combination with actual cases.It was preliminarily discussed that the water level showed rapid high-frequency oscillation and multiple oscillations during distant major earthquakes,gradually attenuated,and then returned to normal.In short-distance major earthquakes,the water level showed steps up and down.The duration and amplitude of both were related to the magnitude and well-to-epicenter distance.The results show that the coseismic response amplitude of water level of Shilin well is correlated with well-to-epicenter distance and magnitude,but it is not completely linear.The coseismic response time is later than the time when the earthquake occurs,and there is a lag.The relationship between magnitude,well-to-epicenter distance,and lag time is positively correlated.The larger the magnitude,the farther the distance,the longer the lag time;the smaller the magnitude,the closer the distance,the shorter the response time.关键词
