Abstract:Social media has become the core carrier for disseminating emergency information and intensifying public opinions.This study took the Liupanshui MS4.6 earthquake in Guizhou Province on July 24,2024 as an example,collected text,address,and time data from social media within 48 hours after the earthquake.This study investigated the focus themes,emotional characteristics,spatial distribution,and temporal changes of public opinions on this earthquake.The research results indicate that the peak of event discussion occurs 4 hours after the earthquake,with themes including earthquake zone safety,earthquake sensation description,earthquake event experience,blessings,and gratitude.In terms of emotional evolution,neutral emotions account for a relatively high proportion in the early stage,and they gradually turn into positive emotions as there are no reports of casualties or property damage within 20 hours after the earthquake.In terms of spatial distribution,comments are mainly concentrated in the Guizhou region,particularly the provinces and surrounding areas where earthquakes have occurred,as well as the central and eastern regions.The results of this study can provide decision support or theoretical reference for post-earthquake network public opinion analysis and disposal in areas with fewer earthquakes.
