Real-world disaster training is extremely time-consuming, expensive and difficult to organize. Because of this, real disaster training exercises are rare and there is a great need for efficient and affordable solutions to make training available at the point of need. In a project by the Institute of Media and Educational Technology at the University of Augsburg, a prototype for an online training scenario was created in Second Life, simulating a cargo plane crash over a suburban area. Within this disaster site, the individual player has to perform a triage with various injured persons and manage multiple spreading fires.
