"Social media plays a critical role in natural disasters as an information propagator that can be leveraged for disaster responses. This study analyzed the online user engagement on social media during the 2016 Louisiana Flood through the lens of Social Network Analysis (SNA). Our findings revealed temporal and spatial characteristics of online social engagement as well as a trend of online users' interests during the flood. We also identified how social capital/infrastructure and community leaders were engaged in improving a flood inundation map. The results will assist emergency agencies and organizations to understand characteristics of social media and the user behaviors during disasters."
