Why: disasters can co-occur (hurricanes cause floods, earthquakes cause landslides, etc. , mortality can be difficult to count (famine, epidemics, a general lack of census taking (in developing countries) 14-hour power blackout: love canal toxic waste spill: chemical spill, children born with birth defects, three mile island nuclear meltdown, therefore, a specific definition of a disaster has been developed. Defining disasters: a threshold has been developed by the centre for research on the epidemiology of. Disasters (cred): 10 or more deaths per events or, 100 or more persons affected (injured, homeless, etc. ) Or: government declaration of disaster or, plea for international assistance, exceptions to the cred threshold, for droughts or famines, at least 2000 persons affected, for technological disasters, 5 or more deaths per event. Disasters and impacts: impacts vary greatly on type, example, earthquakes tend to cause more deaths than tornadoes.
