About crustal velocity model of Inner Mongolia region
摘要
Abstract
According to the seismic network earthquake observation report of Inner Mongolia from 2009 to April 2014 and the location residual of South China model,we found that there is certain difference between South China model and the Inner Mongolia region geological structure and the model need to be revised. On the basis of earthquake and blasting vibration of linear iftting and reduced travel time curve,using adjustment method of discrete degree,depth and speed,combining previous research results for the initial model,the optimal model for:v1= 6.10 km/s,vPb = 6.60 km/s,vn = 8.05 km/s is get by Hyposat searching of 59 events. Results show that positioning residual of the model of South China (catalog) is signiifcantly higher than that of the optimal model. The mean epicenter differential of optimal-catalog is 1 km lower than the South China-catalog mean,which shows that the optimal model conforms to the Inner Mongolia region geological structure features.关键词
