Tsunamis leave few survivors or injured victims but an enormous amount of property and ecological damage. Earthquakes tend to result in both a large number of deaths and a large number of orthopedic injuries. It is our instinct, and I believe a correct one, to focus on locating and assisting injured survivors in the immediate aftermath of an emergency. The 2010 Haitian...
