Since the devastating Indian Ocean tsunami in 2004, the United States has made progress in several areas related to detecting and forecasting tsunamis, including the expansion of a sensor network and improvements to hazard and evacuation maps. However, many U.S. coastal communities “still face challenges in responding to a tsunami that arrives in less than an hour after the triggering event,” according to a U.S. National Research Council report released on 16 September.
