A<unk>  (often shortened to<unk>  describes an incident in which emergency medical services resources, such as personnel and equipment, are overwhelmed by the number and severity of<unk> es. For example, an incident where a two-person crew is responding to a motor vehicle collision with three severely injured people could be considered a<unk> . The general public more commonly recognizes events such as building collapses, train and bus collisions, plane crashes, earthquakes and other large-scale emergencies as<unk> s. Events such as the Oklahoma City bombing in 1995 and the September 11 attacks in 2001 are well-publicized examples of<unk> s. The most common types of<unk> s are generally caused by terrorism,<unk> -transportation accidents, fires or natural disasters. A multiple<unk>  incident is one in which there are multiple<unk> es. However the key difference from a<unk>  is that in a multiple<unk>  incident the resources available are sufficient to manage the needs of the victims. The issue of resource availability is therefore critical to the understanding of these concepts. One crosses over from a multiple to a<unk>  when resources are exceeded and the systems are overwhelmed
