Since 1988 the WHO Collaborating Centre for Research on the
Epidemiology of Disasters (CRED) has been maintaining an Emergency
Events Database - EM-DAT. EM-DAT was created with the initial support of
the WHO and the Belgian Government.
EMDAT contains essential core data on the occurrence and effects of
over 12,800 mass disasters in the world from 1900 to present. The
database is compiled from various sources, including UN agencies,
non-governmental organizations, insurance companies, research institutes
and press agencies.
For a disaster to be entered into the database at least one of the
following criteria must be fulfilled:
- 10 or more people reported killed
- 100 people reported affected
- declaration of a state of emergency
- call for international assistance
This database may be searched by country of origin or type of
disaster and limited to a specific year or region.
