| 摘 要： | 选取2015-2018年辽宁测震台网记录的10条M_L>2.5的三种类型地震,运用3~20个台站分别对地震进行重新定位,将得出的结果与编目结果进行对比,最终得到一个线性曲线。结果表明,对于网缘地震应选取8~10个台站,网内地震选取5~7个台站进行定位可以保证速报结果的准确和速度。

| Abstract: | Three different types of ten ML>2.5 earthquakes are selected recorded by liao-ning seismic network from 2015 to 2018.Three to twenty stations were used to relocate the earthquake.The results were compared with the cataloging epicentral distance results.Finally it will conclud a linearity curve.The results show that eight to ten stations are selected for the outland earthquakes,five to seven stations are selected for the inland earthquakes to guarantee the accuracy and speed of the rapid reporting result. |
