Earthquake emergency management consists of three critical stages:the “start-up period,” the “black box period,” and the “golden period”. Addressing the demand for customized information dissemination across these stages is a pressing scientific challenge in the field of earthquake emergency services. This study, based on questionnaire surveys and public opinion retrieval statistics, employs the standard score comparison method to standardize and quantify the channels and content of earthquake emergency information dissemination. The findings are summarized as follows: ①Government departments should formulate earthquake emergency information dissemination strategies by leveraging data from historical earthquake cases. These strategies should prioritize information with high social demand at different stages of emergency response, monitor public concerns in real time, and adjust dissemination content accordingly. ②Public-oriented information dissemination efforts should maximize existing communication channels, strengthen collaboration with mainstream new media platforms, and establish dedicated information release windows. Real-time dynamic earthquake updates should be delivered to the public via high-traffic, widely disseminated new media outlets. ③Developing a multi-level, priority-based earthquake information dissemination strategy enhances the societal benefits of emergency information services, ensuring their effectiveness and timeliness.
