【摘要】 权重定位方法考虑了台网中震中距长短不同台站对定位的贡献差异,计算的事件位置精度明显提高。该方法对台网布局不过于苛刻,特别是台网布局不合理时,虚波速度法往往无法给出可靠的定位数据,而权重定位能够给出较好的结果。更多还原

【Abstract】 Weighting location sufficiently considers that Length or short of the epicenter distances have different contribution to seismic location.Precision calculated by the weighted method is distinctly improved as compared with other methods.This method does limited station quantity,and layout of seismologic observation network.In particular,when the layout of seismic network is not reasonable,method of virtual wave velocity do not usually provide reliable data.However,weighting location can give better location results.更多还原
