Tsunami preparedness progress

Abstract

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.
