A Cloud-based China's Landslide Disaster Database (CCLDD) Development and Analysis

Landslide is among the most dangerous natural disasters globally, frequently causing a large number of casualties and economic damages. Especially in China, there suffers the largest of deaths in the world [1]. At present, landslide events have been reported increasingly from newspapers, magazines and many cyber-hazard databases. Cyber-hazard database concerned provides powerful functions, such as query, update, share, management, mass storage and so on. However, there is often a lack of specific spatiotemporal characteristics of landslide impacts or a failure to visualize complete statics of landslide records due to variable entry criteria. We developed China's landslide disaster community cyber-infrastructure with cloud computing service integration and data collection, providing statistical landslide visualization in the period 1949-2011 based on Google platform. This work indicates cloud computing is further integrated into this cyber-infrastructure by utilizing public cloud services provided by Google, which effectively accelerates the speed during landslide data processing and visualization over the internet.
