The tsunami problem for the coast of the Caribbean basin is discussed. Briefly the historical data of tsunami in the
Caribbean Sea are presented. Numerical simulation of potential tsunamis in the Caribbean Sea is performed in the framework of
the nonlinear-shallow theory. The tsunami wave height distribution along the Caribbean Coast is computed. These results are
used to estimate the far-field tsunami potential of various coastal locations in the Caribbean Sea. In fact, five zones with
tsunami low risk are selected basing on prognostic computations, they are: the bay "Golfo de Batabano" and the coast of
province "Ciego de Avila" in Cuba, the Nicaraguan Coast (between Bluefields and Puerto Cabezas), the border between Mexico
and Belize, the bay "Golfo de Venezuela" in Venezuela. The analysis of historical data confirms that there was no tsunami in
the selected zones. Also, the wave attenuation in the Caribbean Sea is investigated; in fact, wave amplitude decreases in an
order if the tsunami source is located on the distance up to 1000 km from the coastal location. Both factors wave attenuation
and wave height distribution should be taken into account in the planned warning system for the Caribbean Sea.
