摘要
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.
