Document Summary
Maintaining databases on disaster events can be difficult. Why: disasters can co-occur (hurricanes causes floods, earthquakes causes landslides, etc, mortality can be difficult to count (famine, epidemics) A general lack of census taking (in developing countries) Some people may consider certain events to be disasters while other people may not. Examples: eastern canada 1998 ice storm no power in the middle of january, walkerton tainted water , canada/u. s. 14-hour power blackout: love canal toxic waste spill, three mile island nuclear meltdown. Therefore, a specific definition of a disaster has been developed. A threshold has been developed by the centre for research on the epidemiology of. 10 or more deaths per event 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.
