    摘要:

    本文收集整理了2001 ~ 2010 年海南琼海加积井水位对震中距小于8000km、MS≥7. 8 的远大震的同震响应资料,统计了水位变化的形态,分析了同震响应水位变化的幅度与震级及井震距的关系,核实了出现水位变化时的地震波震相。结果表明,同震响应形态表现为以阶升为主,无振荡类型的变化;水位的变化幅度与井震距、震级有一定的关系;该井的同震响应表现出一定的方向性;引起同震响应的地震波大多为面波,有一部分为周期较长的S波。

    Abstract:

    In this study,we analyzed co-seismic responses of water level in the Jiaji well during the strong earthquakes ( MS ≥7. 8 ) from 2001 to 2010 with the epicentral distance less than 8000km. We counted the co-seismic form of the water level,and analyzed the relationship among the amplitude of water level,the magnitude and the epicentral distance,and then checked the seismic wave phases during the changes of water level. It was shown that : (1 ) the co-seismic forms of water level mainly represented step-increase with no oscillation; ( 2 ) the amplitude of water level had a certain connection with epicentral distance and magnitude; ( 3 ) co-seismic responses of Jiaji well showed a certain direction,;(4) the most of co - seismic responses were caused by surface waves,some of which had long period.
