  • Actual amplitudes at the coast MAY vary from forecast amplitudes due to uncertainties in the forecast and local features. in particular maximum TSUNAMI amplitudes on atolls and at locations with fringing or barrier reefs will likely be much smaller than the forecast indicates.
  • For other areas covered by this product a forecast has not yet been computed. the forecast will be expanded if necessary in subsequent products.
