| 摘 要： | 使用联合定位方法对2008年5月12日至7月7日M<,L>≥3.0的1 028次地震进行重新定位.针对EVT格式的波形数据,重新求取视出射角参数和到时参数,建立地震波到时与视出射角联合定位方法.视出射角参数对深度较敏感,其联合定位结果能保证经度和纬度方向上的定位精度,特别是能提高对深度的分辨能力.联合定位结果表明,地震...

| Abstract: | In this paper 1028 aftershocks from May.12 to Jul.7,2008 have been relocated precisely using Multiparameter Seismic Joint Location method.The parameters of apparent emergence angles and arrival time are extracted according to the wave data with EVT format.The objective function in the method of Multiparameter Seismic Location with apparent emergence angles and arrival time was founded.The apparent emergence angle has the very strong sensitivity to depth.The results of Multiparameter Seismic Location are abl... |
