摘要:
本文采用目前地震预警系统常用的基于等时差面与维诺图相结合的联合概率地震定位方法,选取了日本K-NET台网记录到的204次网内地震及22次网外地震,分别进行了3台至8台重新定位。研究结果表明,在平均台站间隔约25 km的条件下,地震预警定位残差呈对数正态分布,且随着定位台站数量的增加定位残差呈减小趋势;网内地震的定位残差较小,平均残差在1~4 km之间;而网外地震的定位残差较大,平均定位残差约10 km。
Abstract:
The probabilistic seismic location method which based on the Equal Difference Time (EDT) surface combing with information of Voronoi cell is one of the most commonly used real-time location methods in Earthquake Early Warning (EEW) systems. 204 inner-net earthquake events and 22 out-net earthquake events that selected from the K-NET strong motion network of Japan are re-located by using this location method. The performance of the location method is evaluated by using 3 triggered stations re-location, 4 triggered stations re-location, and up to 8 triggered stations re-location respectively. The results show that under the condition of an average station interval of about 25 km, the residuals of location are log-normally distributed, and the location residuals decrease with the increase of the number of triggered stations. The average residuals of inner-net events determined from 3 triggered-station to 8 triggered-station location are in a range of 1 to 4 km. The residuals of out-net events are larger compared with that of inner-net events, the average residuals of out-net events is about 10 km.
