Abstract
Natural disaster events worldwide occur frequently. They are heterogeneous, dynamic, and may occur in sequence. Additionally, some of these natural disasters may be a complex of multiple simplex events. Duo to the lack of any uniform event modeling criteria and platform, it's difficult to collaborate and reuse the disaster events information. In view of the cycle of natural disasters, this paper analyzed the existing methods of describing disaster events and presented a framework for disaster events modeling and management based on OGC EML standard. A case study of the Liangzi Lake flood event occurred in summer 2010 was used to illustrate the feasibility of the proposed framework in modeling natural disaster events. Furthermore, it can also provide important support in other environmental applications.
