河北台网2015速度模型与原模型应用并运行对比研究
|
摘要
使用河北数字地震台网2016年部分速报地震和编目地震数据,利用测震软件ISDP中的盖格法和MSDP中的单纯型定位方法,采用2015模型对以上地震数据进行定位分析,将2015模型的定位结果与现模型及相同定位方法得到的速报及编目结果进行对比、分析,总结了2015模型在本台网使用过程中存在的问题并提出了建议,结果暂定河北台网目前采取模型选择性使用的模式,对进一步提高河北台网地震速报及编目定位精度有一定的意义。
Based on the seismic data of digital seismic network of Hebei digital seismic network in 2016,using the different location programs in the seismic software Isdp and Msdp, the above seismic data are located and analyzed by using 2015 model. the location results of the 2015 model are compared with the current model and the same location method. The problems existing in the use of the 2015 model are summarized and some suggestions are put forward. The conclusion is that the current model using by Hebei station is temporarily adopted. It is of great significance to furthermore improve the accuracy and cataloging accuracy of Hebei station.
