Abstract
Several washover fans breaking through the spit of Valdelagrana existing in middle 18th Century in the
Cuadalete estuary (Bay of Cadiz) are interpreted as the trace of the exceptional tsunami generated by the
AD 1755 Lisbon earthquake, based on geological, morphological and historical arguments.
[RESUMEN]A partir de pruebas geológicas, morfológicas e históricas interpretamos varios abanicos de sobrepaso
(washover) que cortan la flecha de Valdelagrana activa a mediados del siglo XVIII en el estuario del Cuadalete
(Bahía de Cádiz)como la huella del excepcional tsunami producido por el terremoto de Lisboa de 1755.
