Abstract: After the completion of the earthquake emergency command technology system of Hebei province, the earthquake intensity distributions calculated by the seismic disaster assessment software of the system is not consistent with the earthquake damage records due to the experiential intensity attenuation coefficients.On basis of earthquake intensity data, using the regression analysis method, this paper provides new intensity attenuation coefficients of Hebei and its adjacent area.Through the software validation, with the new intensity attenuation coefficients, the results of the intensity range given by the software are more consistent with the records.
