The Disaster Mapper is an interactive map of Australia that shows over 50 disaster events that have occurred at different times, ranging from the early 1900s through to the most recent events. Each event is supported by statistics, images, videos and text. The events are searchable by location, time or type of disaster.
This site also has a whole host of other great resources and lesson plans revolving around disaster management relative to the Australian Curriculum
