- Abstract:
-
Through cleansing,classification,and excavation the data of Sina Micro-blog,we analyzed the spatial and temporal characteristics of public opinion information of Tonghai MS5.0 earthquake on Aug.13 and Aug.14 in 2018.The disaster information is divided into human reaction and utensil reaction,which accounts for more than 79% of the amount.The correlation between the daily activity of micro-blog and time is obvious.After the earthquake,there are many fluctuations of the daily activity of micro-blog.The number and spatial distribution of micro-blog are closely related to the epicentral distance,and follow the distance attenuation effect.As rumors spread during the earthquake,people in the earthquake-stricken areas were mainly in negative mood,and the mood of panic,sadness and doubts increased.
