| 英文摘要 | Location capability and its spatial distribution of the beijing capital digital seismograph network were estimated using 'repeating earthquakes' or 'earthquake doublets' from 2002 to 2006. taking the definition of waveform correlation by schaff and richards([1]), it is assumed that the 'repeating events' or 'doublets' are separated by no more than 1km, the network-measured apparent distances of 'doublets' indicates the order of magnitudes of the location error, and the difference of travel times between the 'repeating events' indicates the error of phase picking. waveforms of 0.5 similar to 5.0 hz band-pass filtered bb/vbb recordings and 1.0 similar to 5.0 hz band-pass filtered sp recordings are cross-correlated, recognizing 859 'repeaters', being 24% of the whole events. it is observed that the average accuracy of the routine location by the beijing capital digital seismograph network is of the order of magnitudes of 5km in the northern part where seismic observational condition is better, and of 13km in the south and west part where seismic observational condition is to be improved. |
