Early warning for regional geo-hazards based on the weather condition,in China,was started from2003. Warning information was published to the public social,alert to prevent rain triggered landslides and debris flow hazards. This paper outlined the achievements of early warning for regional geo-hazards,in terms of working mechanism,technical methods and warning effect during 2003-2012. First,aspects of the working mechanism,a grading operation mode including national,provincial,and municipal and county grade was used. Then it was continuously improved cooperation and information sharing. Secondly,technical methods,two warning models and operation system were created,that is implicit statistics( critical rainfall criterion)and explicit statistics( geological environment and rainfall multi-parameter calculation). Those models effectively guided the "resident self-understanding and self-monitoring"and professional monitoring in typical areas. Finally,warning effectiveness,according to the release of warning information through television,internet,SMS and other medias, the awareness of the public, especially community, was significantly enhanced,the knowledge of mitigation was gradual grown. An idea of rational use of geological environment and active prevent disasters has been a consensus in China.
