备注

社交媒体成为突发事件信息传播与舆情发酵核心载体。以2024年7月24日贵州六盘水4.6级地震为例,采集震后48h的社交媒体数据中的文本、地址、时间数据,研究了此次地震舆情的关注主题、情感特征、空间分布和时序变化。研究结果表明:事件讨论峰值出现在震后4h,主题包含震区安全、震感描述、地震事件感受、祝福和感谢等内容;在情感演化方面,前期中性情绪占比较高,震后20h内无伤亡和财产损失报道,逐渐转为积极情绪;在空间分布上,评论主要集中在贵州地区,以发震省及周边、中东部地区为主。结果可为少震地区的震后网络舆情分析和处置提供决策支持或理论参考。
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.
