A Web-GIS hazards information system of the 2008 Wenchuan Earthquake in China

The typical earthquake hazards chain includes main shock, surface ruptures, aftershocks, and earthquake-induced landslides, leading to structural damage and casualties. Lots of investigation and research were published. But there is no Web-GIS platform to integrate earthquake hazards chain data and compare relative research results. This paper studies compiling such a hazards chain database and building a cloud-based Web-GIS system of the 2008 earthquake. The system introduced by this paper provides buttons and tools to browse, query and analyze map data. In addition, this system is open to anyone to add data for viewing and comparing in the web map. The result showcases that the cloud-based system runs efficiently and flexibly. The multi-scale and multi-source data can be integrated into a “one-map” system by well-design map services and geodatabase.
