Abstract

Possibilities of forecasting of a tsunami characteristics for areas with small base of historical tsunami are discussed. The PTHA method (Probabilistic Tsunami Hazard Assessment), which cornerstone the statistical analysis of real and predictive earthquakes which number is rather big, with the subsequent calculation of waves of a Tsunami from possible earthquakes is for this purpose used. This method for assessment of long-term tsunami danger on the Mediterranean coast of Egypt is used. It is shown that the predicted wave heights change along the coast that is caused by heterogeneity of topography of a coastal zone and features of the chart of radiation of a tsunami in the sea. The predicted wave heights for 1000 years change within 0.83.4 m.
