When Hurricane Katrina ravaged the U.S. Gulf Coast in 2005, Facebook was the new kid on the block. There was no Twitter for news updates, and the iPhone was not yet on the scene. By the time Hurricane Sandy slammed the eastern seaboard last year, social media had become an integral part of disaster response, filling the void in areas where cell phone service was lost while millions of Americans looked to resources including Twitter and Facebook to keep informed, locate loved ones, notify authorities and express support. Gone are the days of one-way communication where only official sources provide bulletins on disaster news.
