【Abstract】 The primary results have been obtained by the analyses on the deviation of macroscopic epicenters from relevant microscopic epicenters determined rapidly after the 139 earthquake events occurred during 1989~2004. Further study has proved the normal distributions exist in both the east and west parts of Chinese mainland partitioned along meridian 105°E. The empirical two-dimensional normal distribution functions for the deviations are pre-sented in the paper. The results are of significance in reducing uncertainty of losses assessment immediately after a destroyed earthquake.更多还原
