Abstract: With the continuous development of the Internet and social media, the hazards posed by disasters at the informational level have become a critical concern, and disaster rumors epitomize these hazards. The emergence and spread of such rumors can incite panic among the public and destabilize society, making the control and management of disaster rumors a widely recognized necessity. However, the majority of attention has been directed at typical disaster rumors associated with single types of disasters within isolated hazard scenarios. Compound disaster rumors, which occur in multi-hazard scenarios and involve multiple types of disasters, have not yet received sufficient attention. This study aims to outline the characteristics of compound disaster rumors and propose governance strategies tailored to these complex scenarios. By doing so, it seeks to support and enhance disaster information governance in multi-hazard scenarios.

Key words: Compound disaster rumor, Online rumors, Rumor governance, Debunking strategies, Disaster information governance
