Citizens, local governments and crisis response organizations are increasingly using social media to maintain situation awareness during large-scale and complex crises. However, social media generates enormous volumes of data during such major events, easily causing information overload. Therefore, to make it easier for disaster responders to use these already available reports in real-time decision-making, we have developed CrisisTracker.

The system makes it possible for anyone with internet access to collaborate with other volunteers in organizing crisis-related information already available on social media. By doing so, remote volunteers can from home directly help improve the situation awareness of on-the-ground disaster responders. For more information about the system, please visit the CrisisTracker website.
