         I don't mean to nit pick, but there are alot of variables 
         associated with earthquakes. The 2 or 3 types of waves
         involved with movement in the earth's crust, the soil 
         content and density, the location of the epicenter in 
         relation to the building/bridge. Is your bridge in water?
         This would have a substanstal effect on what would happen   
         to it. Would'nt it make sense to select a VR icon for
         earthquake instead of stamping your feet? What if you were
         marching? Would your VR start into earthquake mode? A quick
         3-D ckets of a bridge would hardly due justice to a VR/
         simulation of an earthquake, since all major and minor
         trusses, supports, guy-wires or whatever will all effect 
         the final outcome. Gee, world modeling is a real pain.... :-)

         See ya...
