Analysis of fatality, injury, evacuation and cost data using the Bradford Disaster Scale

Data sets were compiled from the MHIDAS data bank for incidents where there had been five or more fatalities, ten or more injuries, 50 evacuations, or US$1 million damage. The data were converted to magnitudes on the Bradford Disaster Scale and analysed using maximum likelihood. Parameters determined from the estimation procedures were compared for compatibility between themselves and the results of analyses using other data.
