Effective coordination is essential for post-disaster reconstruction. Presently, however, there are relatively few tools to help organizations manage coordination and communication of post-disaster construction activities. Given the recent increase in use of social media platforms, we examine the use of Twitter following Super Typhoon Haiyan (Yolanda) in the Philippines.  A network of organizations in the infrastructure sector is created to capture the coordination structure, as depicted through social media, analyze organizational messaging and determine key actors. A content analysis of tweets further examined emergent themes in the distribution of information through Twitter.  This network perspective lends insight into future applications of how organizations can leverage social media as a means of sustained coordination for long-term, on the ground efforts extending past initial emergency relief phases.
