Abstract: The software system consists of the historical data base of the earthquake casualties,the population data base and the calculating programs.The number of casualties by Tangshan earthquake and Xingtai earthquake was collected to build up the historical data base in which the injured can be divided into the dead,the serious injured and the light injured.The main type of the buildings related to the record in historical data base was given by the statistical results according to the interpretation from aeral photos which were taken after th shock.Based on the historical data,the death ratio related to the building for each intensity was calculated,so did the serious injured and the light injured.The population data base in Beijing and its adjacent areas,using the number of populations by the end of 1994,is built up to meet the needs for evaluating the casualties in the assumed coming earthquake.A special program designed makes the evaluating casualties as quickly as possible,where the intensity lines is digitized by the digiter,and the record in population data base is checked by the intensity lines to determine the related values.It follows that the mumber of evaluating casualties should be available in a short period of time after shocks.The system formulates the evaluating method in taking the probabilities of people staying in the buldings in each time as a modification factor to correct the number that varies with the earthquake occurring time.As a subsystem of evaluating earthquake disasters,it is mainly used in fast evaluations.
