One of the prime objectives of disaster response management is to gain control of the disaster situation as rapidly as possible. Observations have shown that coordination and communication between response teams during disasters is essential for gaining control of the situation, but is often inadequate in past disasters (Auf der Heide, 1989) and often suffers from up-scaling difficulties. Examples were the September 11th attack in New York in 2001 (BBC News, 2002) and the explosion on the premises of a professional firework assembly site, which completely destroyed or severely damaged some 480 houses and some 100 small-medium sized enterprises in the town of Enschede in the Netherlands in 2000 (Oosting, 2001).
