"The Canadian Disaster Database (CDD) contains detailed disaster information on more than 1000 natural, technological and conflict events (excluding war) that have happened since 1900 at home or abroad and that have directly affected Canadians. The CDD tracks "significant disaster events" which conform to the Emergency Management Framework for Canada definition of a "disaster" and meet one or more of the following criteria:
10 or more people killed
100 or more people affected/injured/infected/evacuated or homeless
an appeal for national/international assistance
significant damage/interruption of normal processes such that the community affected cannot recover on its own
...A geospatial mapping component has been added to the CDD."
