Data criteria

Data criteria

The database includes events that meet one or more of the following criteria:

• 10 or more people killed
• 100 or more people affected/injured/evacuated or homeless
• an appeal for national/international assistance
• historical significance
• significant damage/interruption of normal processes such that the community affected cannot recover on its own

The contents of the database undergo constant revision as new disasters occur and more information about past disasters becomes available. Cost and loss data in particular are subject to regular update since there are currently no standardized guidelines for collecting this type of information.

Disclaimer

Where there has been no finding of fact by a court of law in criminal, civil or administrative proceeding, the facts set out in this database are alleged facts.
