- Abstract:
- In order to accurately monitor and assess the risk of earthquake-related public opinion and to correctly guide the social opinion,based on the theory of supply-and-demand deviation,this paper constructs a risk assessment index system of the earthquake-related public opinion using a combination weighting method which consists of the analytic hierarchy process and the entropy method.The study utilizes data samples from the posts and comments on Sina Weibo,the largest social software platform in China within 7 days after the Lushan MS6.1 earthquake,the Maerkang MS5.8 earthquake,and the Luding MS6.8 earthquake which occurred in Sichuan province in 2022,to evaluate the risk of public opinion on these three earthquakes.The results show that the post-earthquake 24 hours is a critical period for the earthquake-related public opinion.The higher magnitude or the more aftershocks of an earthquake,the larger the fluctuation of the public opinion risk index.The constructed risk assessment index system is suitable for the index measurement,dynamic observation,and evolution-law analysis of multiple risks of the earthquake-related public opinion.The risk assessment index system can provide a reference for government's emergency response and for the mainstream social media's public opinion guidance after destructive earthquakes.
