【摘要】 利用上海综合深井观测系统中两分向倾斜仪记录的25Hz采样观测数据,与相邻台站地震仪对东海MS7.0中源地震进行地震定位结果对比分析。结果显示发震时刻最大误差仅0.06s,震中位置最大误差5.1km,并且定位结果都保持了较小的定位残差。因此高采样率深井地倾斜仪记录的观测数据可以用于地震的定位分析。更多还原

【Abstract】 We compared earthquake location of the MS 7.0 intermediate-focus earthquake in East China Sea obtained by the 25Hz sampling observation data recorded by 2-component tiltmeter installed in comprehensive seismic observation system in deep borehole in Shanghai with the observation data recorded by seismometer of seismic stations in its adjacent area. The results show that the maximum error of the origin time and the epicenter location is only 0. 06 s and 5.1 km respectively,and the residuals of earthquake location results is smaller in the earthquake location by using these two observation data,which show s that the observation data recorded by tiltmeter in high sample rate in deep borehole can be used as the earthquake location analyze.更多还原
