The intensity of the earthquake alone does not predict the size of a tsunami
… or even if a tsunami will occur.Slide5
Tsunami detection buoys
DART® tsunami buoys measure the size of a tsunami, in the open ocean, before it comes ashore
5Slide6
DART® Buoys are strategically located throughout the ocean
Real-time, high resolution buoy data is used to refine the forecast - while the tsunami is still propagating through the ocean.
