Various disasters have been a serious threat to human and are increasing over time. The reduction and prevention of
hazard is the largest problem faced by local governments. The study of disasters has drawn more and more attention
mainly due to increasing awareness of the socio-economic impact of disasters. Hubei province, one of the highest
economic developing provinces in China, suffered big economic losses from geo-hazards in recent years due to frequent
geo-hazard events with the estimated damage of approximately 3000 million RMB. It is therefore important to establish
an efficient way to mitigate potential damage and reduce losses of property and life derived from disasters. This paper
presents the procedure of setting up a regional geological hazard forecast and information releasing system of Hubei
province with the combination of advanced techniques such as World Wide Web (WWW), database online and ASP
based on WEBGIS platform (MAPGIS-IMS) and rainfall information. A Web-based interface was developed using a
three-tiered architecture based on client-server technology in this system. The study focused on the upload of the rainfall
data, the definition of rainfall threshold values, the creation of geological disaster warning map and the forecast of geohazard
relating to the rainfall. Its purposes are to contribute to the management of mass individual and regional
geological disaster spatial data, help to forecast the conditional probabilities of occurrence of various disasters that might
be posed by the rainfall, and release forecasting information of Hubei province timely via the internet throughout all
levels of government, the private and nonprofit sectors, and the academic community. This system has worked
efficiently and stably in the internet environment which is strongly connected with meteorological observatory.
Environment Station of Hubei Province are making increased use of our Web-tool to assist in the decision-making
process to analyze geo-hazard in Hubei Province. It would be more helpful to present the geo-hazard information for
Hubei administrator.
