Desastres naturales en Canarias. La costa como espacio de riesgo en Tenerife

Abstract

In the context of the natural disasters in the Canary Islands, the importance of marine seals in the island of Tenerife is analyzed. The Tenerife coastline is highly urbanized and is, therefore, a risk area because of the negative effects that this phenomenon can cause. The study of the wave and the wind behavior, between 1985 and 2003, makes it possible to identify and characterize 30 adverse coastal events of a total of 65 temporary produced. The examination of a series of significant events, such as those that occurred on 7/I/2000, 15/XI/2002 and 13-14/IV/2003 on the north and west sides of the island and 11-13/IV/1987,  9-11/X/1998 and 6-7/I/2002 in the east and south, can also be used to determine the atmospheric conditions caused by marine storms and to indicate the dominant modalities in the coasts according to their orientation. The result is the establishment of two types of storm: those of swell in the north and west coast, fruit of a depression above 40º N, and of sea in the east and south, coinciding with an anticyclonic configuration or a depression over the archipelago.
