Social media (SM) are forms of information and communication technology disseminated through social interaction. SM rely upon peer-to-peer (P2P) networks that are collaborative, decentralized, and community-driven transforming people from content consumers into content producers. The role of SM in disaster management galvanized during the world response to the 2010 Haiti earthquake. (Pew 2010) During the immediate aftermath, much of what people around the world were learning about the earthquake originated from SM sources. (Nielsenwire 2010) During the first 2 weeks following the earthquake, “texting” mobile phone users donated over $25 million to the American Red Cross. (Sysomos 2010) Both public and private response agencies used Google Maps™. Millions joined MySpace™ and Facebook ™discussion groups to share information, donate money, and offer support. SM has also been described as “remarkably well organized, self correcting, accurate and concentrated”, calling into question the ingrained view of unidirectional, official-to-public information broadcasts. (Sutton, et al 2008) SM may also offer potential psychological benefit for vulnerable populations gained through participation as stakeholders in the response. (Sutton, et al 2008) (Laor 2003)

However, widespread use of SM also involves several important challenges for disaster management. Although SM is growing rapidly, it remains less widespread and accessible than traditional media. Also, public officials often view person to person communications as “backchannels” with potential to spread misinformation and rumor. (Akre 2010) In addition, in absence of the normal checks and balances that regulate traditional media, privacy rights violations can occur as people use SM to describe personal events and circumstances.
