According to the meteorological, wind, rain, and water data provided by the China Meteorological Station and the National Climate Center and the Zhejiang Meteorological Bureau during the Typhoon Liqima, three disaster chain modes are constructed: typhoon-rainstorm, typhoon-gale and typhoon-storm surge. Using case analysis method, the analysis the disaster of Typhoon "Lichma" .The results shows that Typhoon "Lichma" appears to have the characteristics of strong landing intensity, wide influence range, low central pressure, salient extreme, slow moving speed, long land residence time, and high wind and rain intensity. This three disaster chains together lead to secondary disasters such as flash floods, landslides, giant waves, seawater inversion, and seawater accumulation, making the cumulative impact of the disaster far outweigh the impact of the disaster caused by a single disaster, causing a large number of casualties and great economic losses.Countermeasures for disaster reduction in coastal, mountainous, and plain areas in response to typhoon disasters are provided.
