内蒙古地区地壳速度模型在地震定位中的应用
Application of the crust velocity model of Inner Mongolia region in earthquake location
摘要
Abstract
According to random drawing earthquake test in Inner Mongolia between 2009 and April 2014, using Hyposat software, the location residual of the new model is lower. Mean positioning residual obtain with the optimal model is 0.19 s lower and the mean optima-catalog epicenter differential is 1.19 km lower, which shows that the optimal model results is closer to the epicenter catalog results. According to the three dimensional depth distribution, latitude depth according projection and the longitude depth projection, strip shaped gathered around 5 km. The catalog depth scattered between 5 and 10 km, while the optimal model focal depth scattered between 10 and 25 km. It is suggested that the new model is more suitable for seismic observation work in Inner Mongolia network.关键词
