Abstract

Online social activists through social media play an important role in disseminating information during disaster.However the nature and scale of the typical activist’s involvement with social media have remained unexplored topic.This study applies Social Network Analysis to identify the key information brokers, their roles and the type and flow of information exchanges between the online activists in the network structure.The analysis was performed on a dataset consisting of 139 posts from a voluenteer social media group. The findings demonstrate that civilians play crucial role during disaster as information broker and information boundary spanner, bridging different clusters of network.There were 5 important clusters discovered, each orchestrated around different type of supports.The different types of information posted also reflected the integrative supports covering physical, mental and supports offered for the victims.The evolution of clusters during and post period demonstrates the transitions of social media use by the civilians in coping and managing disasters.This finding can serves as a foundation for integrating public and formal efforts during disaster which ideally increase the efficiency of disaster management.
