Early detection of hazards as well as the identification of geographical regions affected by a disaster play a substantial role in timely intervention and planning of disaster relief operations. We provide an overview of the current research efforts at Disaster Resilience Analytics Center for technologies that can facilitate early detection of hazard through collection and analysis of data by remote sensors, as well as identification of hazardous situations through analysis of social media data. The availability of these technologies can help reduce the risk of disasters, thereby improving the resilience of communities.
