“…Following this conclusion, recurrence intervals were deduced (Morales et al, 2008;Ruiz et al, 2008a). The reported sediments are usually interbedded in estuarine or spit barrier sedimentary units that act as effective sedimentary sinks, likely to preserve geomor phological features that witness the palaeoenvironmental changes.…”

Many on-shore studies focused on high energy marine events occurred in the Gulf of Cadiz have been published since the 1990s. Most of the findings came from sedimentary, palaeontological and geomor phological records on estuaries, marshes, beach-barriers (spit-bars), and some coastal lowlands. Recent off-shore investigations in SW Iberia considered turbidite deposits as a proxy to recognise palae oearthquakes in this zone. The comparison of datasets from both on-shore and off-shore records indicate that at least five tsunami events generated by strong earthquakes affected this area during the last 7000 years, previous to the more recent and well-documented 1755 AD Lisbon earthquake tsunami event. The catalogue of Holocene palaeotsunami presented here is supported by geological and geomorphological evidences, but also for archaeoseismic and palaeoseismic evidence and written reports for the more recent events occurred during historical times. The recurrence interval for these catastrophic events can be bracketed between 1200 and 1500 years.

The bay of Cádiz is a coastal area intensively occupied during prehistorical and historical times from which many archaeological remains have been preserved. The bay is a low coast characterized by several spit-barrier systems which close wide estuarine marshes. This kind of coastal environment is especially vulnerable to marine energetic events, like storms and tsunamis, which have occurred in the region during the late Holocene with some regularity. The present work summarizes the different morphosedimentary records of historical marine events identified in the Bay up to date. New chronological and stratigraphical data are presented, obtained from drills, together with different geoarchaeological indicators of historical marine events identified along the Bay. Special attention is paid on the effects produced on the Valdelagrana spit-barrier, where the geometry and age of different historical beach ridges reveal the onset of at least three very energetic events, probably of tsunamigenic origin: one on 2700-2300 cal BP, a second one by the end of the IX century AD and the third one in 1755 AD. The two first events caused deep geomorphological modifications, like river captures, onset of new beach ridge systems, and coastal lowering. Archaeological data indicate that economical effects and infrastructure damage produced by these events conditioned later human occupation and related activities.

“…Thus, in the area of Huelva, Morales et al (2008) found a lumachellic high-energy layer, composed of clean sand, with a variable content of whole shells and shell fragments, quartzite pebbles, and muddy clasts. The authors interpreted this layer as "the sedimentary results of the dissipation of the tsunami wave after the AD 1755 Lisbon earthquake".…”

Evidence of the AD 1755 tsunami consisting of the same type of accretions produced by the re-deposition of earlier sediments, has been recorded at three different height along the coast of Gibraltar: Along a shallow sandy shore, the tsunami wave reached a run-up of 2-3 m, whereas along steep, cliff-lined shores (Rosia Bay) it surpassed 5 m. An overwash deposit was also identified at the bottom of a lagoon (The Inundation), at 0.5 m b.s.l., on the isthmus that joins the Rock with the mainland. Southern submerged platforms (Vladi's Reef) were also affected by the erosional backwash to a depth of 22 m. The tsunamigenic sediments exhibit a bimodal granulometry, mainly composed of sands with a coarser fraction composed of marine faunal shells remains, together with larger clasts derived from the rocky substrate. All remobilized sediments were dated by historical methods and radiocarbon dating.Keywords: Lisbon earthquake, AD 1755 tsunami, run-up, sedimentary record, radiocarbon dating, Gibraltar ResumenSe han registrado evidencias del tsunami de 1755 localizadas a tres alturas diferentes a lo largo de la costa de Gibraltar, todas ellas como resultado del mismo tipo de acreción producida por el re-depósito de sedimentos previos.
