- Abstract:
- Based on the ground motion data of the Yangbi MS6.4 earthquake recorded by the Yunnan Early Warning Network,a variety of spatial interpolation methods are used to obtain the optimal instrumental intensity influence field,and compared with the results from the macroscopic intensity obtained from field survey.The results show that the influence field of instrumental intensity obtained by the ordinary Kriging interpolation method based on the variogram of the exponential model has a good agreement with the macroscopic seismic intensity,which can reflect the overall range of the influence field and characteristics of the actual seismic intensity.The main reasons for the differences between the instrumental intensity influence field and the macroscopic intensity field are the distribution of stations,site conditions,spatial interpolation methods,and the superposition of foreshocks' damage and aftershocks' damage.
