“…To advance the field of disaster research, it is necessary to look beyond single cases and find common patterns across events (Tierney, 2013; Wolbers et al, 2021). While overviews of disaster managers' social media usage exist (e.g., Flizikowski et al, 2014; Reuter et al, 2016; Singla & Agrawal, 2022; Torpan et al, 2023; Wukich, 2019; Zhang et al, 2019), cross‐national data on how disaster management institutions use social media is limited, especially from the perspective of how they may affect social vulnerability (see Orru et al, 2022). We contribute to this line of research by analysing official documents and 95 expert interviews in eight European countries—Germany, Italy, Belgium, Sweden, Hungary, Finland, Norway, and Estonia—and looking for institutional social media practices that may concern pre‐determined vulnerable groups as well as situations stemming from dynamic, contextual factors where potentially anyone may become more vulnerable (see Morsut et al, 2022).…”
