The Hub provides web-based "situation awareness sharing" among volunteers, first responders, government and non-government individuals who may otherwise be unable to collaborate.
The Hub is based around Mediawiki, the same technology powering Wikipedia, and provides an easily referenced, easy to use tool for tapping group knowledge to share essential and current information of a developing crisis situation. The Hub is not intended as the complete answer in situation awareness, just a common starting point for critical information.
