Cuba has its first tsunami danger map

HAVANA, Dec. 9  The National Center for Seismological Research (Cenais) highlighted this Thursday in X the obtaining by specialists from that institution scientific-technical 

of the first tsunami danger map for the Cuban coasts.

Cuba has its tsunami danger map, published the Cenais in reference to the novel investigative result, according to which, the towns most exposed to this type of event are Maisí, Baracoa and Moa, located in the northeastern corner of the country, and the beaches on the northern coast of the eastern half, including Cayo Saetía, Guardalavaca and Cayo Coco.

The presentation of the new map was made in the context of the XI International Congress on Disasters, which is in session until this Friday at the Convention Center in this capital, together with the VII International Firefighters Conference.

An article in the Granma newspaper states that the study was developed with all the scientific rigor and current methodology used by doctors Enrique Diego Arango Arias, head of the National Seismological Service, Bladimir Moreno Toarán and O’Leary F. González Matos.

Arango Arias highlighted that data from all faults with the potential to generate earthquakes capable of producing tsunamis in the geographical area of interest for the country were used.

He highlighted that in the specific case of the tsunami danger on the coasts of Cuba, the map was made on a small scale (1:100,000), while, for the localities most exposed to that type of event, they managed to make the flooding at large scales (1:25,000).

Although the tsunami danger is not high in Cuba, there is a certain risk associated with the occurrence of strong earthquakes in a segment of the Northern Hispaniola fault, located north of Haiti and the Dominican Republic, hence the importance of counting with the aforementioned map, he specified.

In that area, some tsunamis recorded in historical catalogs have been generated, which caused thousands of fatalities in the coastal towns of both countries, such as those that occurred in 1882 and 1946, he stated.

The investigation showed that in the south of Cuba, there are no seismotectonic conditions for the occurrence of earthquakes that trigger tsunamis, which is consistent with the fact that none of the strong earthquakes that occurred on the Oriente fault, and much less in the Caribbean, have generated phenomena of this nature, with damage to the coasts of the Cuban archipelago.
