一次灾害性地震之后，有关部门分别提供的评估数字有时差别很大。该文据全世界地震灾害记录资料，提出并讨论以下事实：各家提供的地震灾害评估数字普遍存在差别。一般比较来看，人员死亡数的差别较小，经济损失数额评估的差别较大。地震灾害经济损失评估的差别，将随着社会经济的发展和文化物质生活的不断提高而继续存在，甚至扩大。 After a devastating earthquake, the assessment figures provided by the departments concerned sometimes vary widely. Based on records of earthquakes throughout the world, this paper presents and discusses the fact that there is a general difference in the number of earthquake disaster assessments provided by various agencies. In general, the difference in the number of deaths is small, and the difference in the amount of economic losses is quite different. The difference in the assessment of the economic losses caused by an earthquake disaster will continue to exist and even expand with the social and economic development and the continuous improvement of cultural and material life.
