...Tucker founded GeoHazards International. His message was simple: Stop thinking of earthquakes and tsunamis as unpredictable, and stop thinking of mass fatalities as inevitable. We know where the faults are, we can estimate when quakes will hit, and we can see trends in shoddy construction. The math says more than two million people will die in this century. But those deaths can be prevented, just as vaccines prevent disease. Instead of waiting to send disaster relief after the next Haiti, fund better construction now. Instead of waiting for the next epidemic, inoculate the world.
