SECTOR is about learning from past events and actions to be better prepared for future crisis situation. During the project, data from past disasters will be gathered and analyzed (qualitative and quantitative approach) for better understanding factors which overweigh about succeed or failure. After analyzes it will be possible to understand why some actions are more efficient and other less and to adopt those good practices in SECTOR. The information gathered will be structurally compiled into an inventory of past events. As a value added to the SECTOR project, the proposed structure will be available in the final Common Information Space as a “past events database”, which will allow users to access event information.
