Generation methodology of isolines of earthquake ground motion

Due to limited financial resources and challenging geographical conditions, the number of seismic observation networks in China is still very small and they are not widely distributed. Therefore, the available earthquake records obtained after an earthquake have been limited. In this paper, auto-generation methods to obtain strong motion isolines under different conditions are proposed. To verify the accuracy of these methods, some examples, including application to the 2008 Wenchuan earthquake, are given.
