the numbers of fatalities , injured (casualties sum of these 2 parameters) estimated, using casualty matrix, table gives percentages of dead, injured, , unscathed among occupants of building collapses. distribution depends on building type.


a building need not collapse injure , kill; @ every damage degree there exists probability casualties result.


the data in casualty matrices poorly known cannot give uncertainties here. however, specialists working on learning more , related problems in estimating losses due earthquakes.
