SharkJumper writes "We here in central Oklahoma, USA are just climbing out of the wreckage of another series of tornadoes. Unlike the tornadoes of May 3rd, 1999, which killed 47 and injured more than 800, we now have much better tornado information and prediction technology. Largely because of this, there have been far fewer injuries, and (as of this morning) no reported deaths. Here in the greater Oklahoma City area, we can even register our storm shelters with the city. After a severe storm, GIS technology is used to create a map for rescuers detailing location and type of the shelter as well as emergency contact information. Rescuers can then use these maps to search for survivors that may be trapped by debris in their shelters."
