Disasters such as res, oods, earthquakes, civil war or terrorist attacks may cause crisis situations. Regardless of the origin, crisis situations are often accompanied by uncertainty of how the disaster will develop, a rapid pace of response operations and the possibility of serious loss of human lives and property if not responded to properly. For these reasons the ability and efciency of responding to crises and unexpected events has become increasingly important throughout the world, particularly in the United States and the United Kingdom in response to the 09/11 terrorist attack on the World Trade Centre and the 7 July London bombings. These events are etched in memory and were those in which humans were ill equipped to respond. Good situational awareness and decision-making support are important factors for minimising property damage and injury, and for saving people’s lives. To provide adequate situational awareness and decision-making support to manage crisis situations, researchers and practitioners in disaster management have urged attention to emergency information requirement capturing, information presentation, information sharing and consequently information-driven decision support through the research and development of emergency response information systems (ERISs). ERISs should support rst responders by enhancing their situational awareness which will lead to better decision making (Klann, 2008).
