NADER AFZALAN* JENNIFER EVANS-COWLEYt MAZIAR MIRZAZAD BARIJOUGH* Abstract: Following a major natural disaster, many turn to social media to communicate about their situation and try to seek help in disaster recovery. With millions of social media posts, it can be difficult for disaster management organizations to tap into these immense social networks to find the data needed and to connect individuals to networks that can provide assistance. This study takes big data analytic methods and applies them to a specific context, examining how active and influential members of Facebook groups aided in disaster recovery following Hurricane Sandy. It uses network analysis methods for finding influential members and a web-survey for learning about their background and volunteer activity inside and outside of their Facebook groups. The findings show that the majority of the active online members are also actively involved in on-the- ground recovery activities. They also have the capacity and willingness to work as volunteers. These members have PhD Candidate, College of Architecture and Planning, and Lecturer, Environmental Design Program, University of Colorado. t Professor of City and Regional Planning and Associate Dean for Academic Affairs and Administration, College of Engineering, The Ohio State University.
