Courtesy V.K. Gusiakov Earthquake Magnitude Tsunami Intensity 4 The intensity of the earthquake alone does not predict the size of a tsunami … or even if a tsunami will occur.

 DART® tsunami buoys measure the size of a tsunami, in the open ocean, before it comes ashore 5

 Real-time, high resolution buoy data is used to refine the forecast - while the tsunami is still propagating through the ocean. DART® Earthquake 6

 Combines Earthquake seismic information Real-time tsunami buoy measurements in the deep ocean Computer models to predict tsunami propagation and coastal flooding  Provides Real-time tsunami propagation forecasts Real-time coastal flooding forecasts*  Installed at the NOAA Tsunami Warning Centers in Alaska and Hawaii NOAA Center for Tsunami Research 7 * For selected coastal communities
