What the record says

NCEI’s account, from the sources it cites.

La Tarde newspaper reported three huge waves that, in Tenerife Island, inundated the littoral of Santa Cruz de Tenerife and San Andres (Figure 1) affecting the Island Council building, the Maritime Avenue, breaking the door of an office and inundating the Navy Command [ref #12939]. Only a woman was injured. These waves have been ascribed to a local landslide close to Santa Cruz, since no earthquakes or other extreme wave events occurred that day [ref #12939]. Based on this information, the waves surpassed heights of 2 m in the Cabildo building and 6 m in the Navy Command. The most likely location of a landslide affecting Santa Cruz would be the 200 m tall cliffs cut in the old massif to the NE of the city, since the littoral to the SW is mostly low rocky coast. A freak wave is discarded as the origin of this event since they are not characteristic in the eastern coast of the island [ref #12939]. (reference #12938)
