Tsunami Factor

Look back at a list of major earthquakes through the years and you’ll see a number of related tsunami events. Perhaps the most memorable in recent history was the December 26, 2004, magnitude 9.0 earthquake in the Indian Ocean, that triggered a series of tsunami (tidal waves) and left some 220,000 people dead. In an I.I.I.  chart of the 10 deadliest world catastrophes between 1970 and 2006, that event ranks third. So yesterday’s announcement by the National Oceanic and Atmospheric Administration (NOAA) that it has completed high-resolution digital elevation models to prepare three east coast communities for tsunami and storm-driven flood threats is a welcome step. The latest models for Long Island, Atlantic City and Daytona Beach provide the framework to accurately forecast the magnitude and extent of coastal flooding during a tsunami or storm surge event. They add to models already in place for some 20 U.S. coastal communities and NOAA expects to build 50 more models in the coming years. Check out further I.I.I. info on flood insurance.
