Abstract

Typhoon is a tropical cyclone with a sustained wind speed ranging from 12 to 13. It is a kind of weather with serious damage. It is of great significance to study the characteristics and causes of disasters caused by super typhoon for disaster prevention and mitigation. Xiamen is located in the southeast coastal area of China, with dense population and developed economy, which is affected by typhoon all the year round. In 2016, the super typhoon “moranti” caused serious damage to the social economy and people’s safety in Xiamen. Based on the theory of natural disasters, this paper studies the causes of “moranti” disasters, mainly analyzes the situation, precipitation, wind power, social conditions, architectural design, social prevention and education from the perspective of the risk of the disaster factors and the vulnerability of the disaster bearing body, and finds that there are still many problems in building typhoon prevention in Xiamen. In order to reduce the loss of buildings in Xiamen area under the extreme typhoon environment as much as possible, the corresponding and feasible protective measures and improvement schemes are put forward.
