PurposeThe purpose of this study is to investigate communication on Twitter during two unpredicted crises (the Manchester bombings and the Munich shooting) and one natural disaster (Hurricane Harvey). The study contributes to understanding the dynamics of convergence behaviour archetypes during crises.Design/methodology/approachThe authors collected Twitter data and analysed approximately 7.5 million relevant cases. The communication was examined using social network analysis techniques and manual content analysis to identify convergence behaviour archetypes (CBAs). The dynamics and development of CBAs over time in crisis communication were also investigated.FindingsThe results revealed the dynamics of influential CBAs emerging in specific stages of a crisis situation. The authors derived a conceptual visualisation of convergence behaviour in social media crisis communication and introduced the terms hidden and visible network-layer to further understanding of the complexity of crisis communication.Research limitations/implicationsThe results emphasise the importance of well-prepared emergency management agencies and support the following recommendations: (1) continuous and (2) transparent communication during the crisis event as well as (3) informing the public about central information distributors from the start of the crisis are vital.Originality/valueThe study uncovered the dynamics of crisis-affected behaviour on social media during three cases. It provides a novel perspective that broadens our understanding of complex crisis communication on social media and contributes to existing knowledge of the complexity of crisis communication as well as convergence behaviour.

Influential Users

The highly influential users on social media platforms may lead the public opinion about public events and have positive or negative effects on the later evolution of events. Identifying highly influential users on social media is of great significance for the management of public opinion in the context of public events. In this study, the highly influential users of social media are divided into three types (i.e., topic initiator, opinion leader, and opinion reverser). A method of profiling highly influential users is proposed based on topic consistency and emotional support. The event of “Jiankui He Editing the Infants' Genes” was investigated. The three types of users were identified, and their opinion differences and dynamic evolution were revealed. The comprehensive profiles of highly influential users were constructed. The findings can help emergency management departments master the focus of attention and emotional attitudes of the key users and provide the method and data support for opinion management and decision-making of public events.

Hazardous Use

The COVID-19 pandemic that hit the world in 2020 triggered a massive dissemination of information (“infodemic”) about the disease channeled through the web and social media. This “infodemic” included also sensational and distorted information about drugs, which likely affected primarily opinion leaders and people particularly active on social media, and subsequently other peoples leading to inadequate choices by individual patients everywhere. In particular, for some drugs approved with other indications, namely chloroquine, hydroxychloroquine, NSAIDs, ACE inhibitors, angiotensin II receptor antagonists, favipiravir and umifenovir, information has spread that has led to a hazardous use. In this article, we analyzed the rationale behind the claim for use of these drugs in COVID-19, the communication about their effect on the disease, the consequences of this communication on people's behavior and the response of some influential regulatory authorities in an attempt to minimize the actual or potential risks arising from this behavior. Finally, we discussed the role of pharmacovigilance stakeholders in emergency management and possible strategies to be put in place to deal with other similar situations in the future.

The purpose of this special issue of the Journal of Emergency Management is to assess the state of disaster preparedness, response, mitigation, and recovery during the COVID-19 pandemic. This article adds to this discussion by examining the results of a national survey of emergency managers in the United States regarding the social media platforms they use to communicate information related to the COVID-19 pandemic, how proficient they feel using them, and what value they see in these technologies during the times of crisis. The authors’ findings help make sense of government responses to the pandemic, as well as contribute to the body of literature on communication and emergency management more broadly. Furthermore, their findings have important implications for emergency management practitioners and educators.
