title: Data from: Performance of social network sensors during Hurricane Sandy

description: Information flow during catastrophic events is a critical aspect of
 disaster management. Modern communication platforms, in particular online
 social networks, provide an opportunity to study such flow and derive
 early-warning sensors, thus improving emergency preparedness and response.
 Performance of the social networks sensor method, based on topological and
 behavioral properties derived from the “friendship paradox”, is studied
 here for over 50 million Twitter messages posted before, during, and after
 Hurricane Sandy. We find that differences in users’ network centrality
 effectively translate into moderate awareness advantage (up to 26 hours);
 and that geo-location of users within or outside of the hurricane-affected
 area plays a significant role in determining the scale of such an
 advantage. Emotional response appears to be universal regardless of the
 position in the network topology, and displays characteristic, easily
 detectable patterns, opening a possibility to implement a simple
 “sentiment sensing” technique that can detect and locate disasters.
