Research on the Crustal Velocity Model of the Yunnan Region and Its Application

Yang Jingqiong;Yang Zhousheng;Zhang Huiyuan;Yunnan Earthquake Agency;  
This paper selects the records of 7,412 earthquakes,each recorded by more than 10 stations in Yunnan between 2009 and 2014 to acquire the traveltime curves.Meanwhile,for improving precision,linear analysis,reduced traveltime curve and interval stability analysis are conducted focusing on the records of 83 earthquakes with M_L≥3.0 recorded each by≥80%of the stations,and by combining predecessors'research results,the initial crustal velocity model of the study area is obtained.By selecting 200 earthquakes with M≥3.0 occurring in Yunnan between 2010 and 2014,using the Hyposat batch location processing method to iterate the initial velocity model,and performing fitting to S waves layered velocity structure,we obtain the crustal velocity model for the Yunnan region,namely,the 2015 Yunnan model,with:v_(P1)=6.01km/s,v_(P2)=6.60km/s,v_(Pn)=7.89km/s,H_1=20km,H_2=21km,v_(S1)=3.52km/s,v_(S2)=3.86km/s,v_(Sn)=4.43km/s.Analysis on earthquake relocations based on the new model shows that most earthquakes occurring in Yunnan are at a depth of 10km-20km of the upper crust.The March 10,2011 M_S5.8Yingjiang and August 3,2014 M_S6.5 Ludian earthquakes are relocated,and the focal depths determined with the new model are respectively close to the precise positioning result and hypocentral distance to the strong motion stations at the epicenters,indicating that the new one-dimensional velocity model can better reflect the average velocity structure of the study area.
