Early warning for Geo-Hazards based on the weather condition in China

摘要

According to national early warning practice for geo-hazards from 2003 to 2005,it is system-atically concluded that the basic characteristics ofgeo-hazards,early warning method and forecast result basedon the geological maps of China in a scale 1:6,000,000. With the contrast of different characters between sus-tained rainfall and typhoon rainfall inducing geo-hazards,the disaster reduction result and some problems arepreliminarily analyzed. Some basic recognition is that early warning to geo-hazards is feasible,national scaleforecast is only to call attention,but can't immediately be used to disaster reduction decision-making. And,thefuture direction is to build a united disaster reduction framework of early warning system including national,provincial and county levels based on weather factors in different scale of area.
