| 摘 要： | Introduction The current earthquake damage and losses assessment is based on the parameters obtained from rapid determination of earthquake location. It has been proved that there exist uncertainties of the rapidly determined parameters. For example, the deviation of fast determined magnitude from the magnitude determined by the international common technique obeys the normal distribu-tion, and such deviation is decreasing year after year with improvement of networks performance (MENG, 1994;… |

| 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 presented in the paper. The results are of significance in reducing uncertainty of losses assessment immediately after a destroyed earthquake. |
