“…In general terms, the longshore and inland inundation from a tsunami would, on average, be expected to be greater than that of a storm. In general terms, and based upon field evidence from 2004 IOT sites, inundation by large, region-wide events is likely to cause multiple breaching of dune systems (Higman et al 2005;Singarasubramanian et al 2006). In other words, multiple breaching assemblages can be formed during one inundation.…”

Background: Despite a position along the passive margin of Africa, the Moroccan Atlantic coast is under the influence of the tsunami threat from earthquakes triggered along the Nubia-Eurasia plate boundary. Along Tangier, Asilah, Sale and Mazagao's coasts, tsunami have been described since historic times. The 1755 Lisbon quake triggered a tsunami that struck the shores of Morocco 60 min after the tremor, the waves reaching from 2 to 15 m in amplitude. The coastal sedimentary record, together with other proxies, is now being experienced to discriminate and reconstruct evidence of prehistoric inundation events.

“…The occurrence of headland intercepted the longshore drift direction and thus, the beach will accreted on the up-drift side and erode on the down-drift side [37] [38]. Coarse grain material can also be found in most pocket beaches, especially those located in the vicinity of rocky headland [39].…”

“…Sediment in the middle region of Terengganu was poorer in sorting value compared to the northern and southern region (Figure 5). This specifies that tidal level and other physical forces in the middle region, especially stations 4, 5 and 6 were given much impacts to the beach as water is known as an excellent medium for sorting mechanisms of all, but only for the finer grain size [39]. This variation of the average values, therefore, reveals the sediment sorting ranged from 0.38 φ (station 7) to 1.06φ (station 6) which both were occurring in August 2008.…”

In general, the Terengganu beaches consist mainly of medium- to coarse-grained sand. Grain sizes were determined by dry sieving sediments; samples represent the upper 15 cm of surficial sediment, collected from the three main geomorphological tidal units during one year observation periods, covering the southwest and northeast monsoon seasons. The result demonstrates a good relationship between the monsoonal processes and the corresponding geomorphological elements. There are some differences between the various geomorphological tidal units, with a subtle trend from the low tide to high tide zone. Grain size decreases slightly from the low tide to the high tide. The sediment size fraction averaging from -0.48phi to 1.87phi. The most fine material was found at Kuala Besut (northernmost Terengganu) while the coarsest particle was found at Seberang Takir. However, the grain size parameters at different beach locations do not suggest a general trend of long-shore variations, except on the beach close to the river mouth. The differences between the seasons were larger than those between the geomorphological tidal units. During the northeast monsoon the mean size was coarser, sorting was worse and the distribution was more positively skewed.

“…Aspecto que ha sido motivo de cuestionamientos, debido a la distinta naturaleza de cada fuente de información, pero que sin embargo es considerada útil y válida para el desarrollo de metodologías y la obtención de resultados que conjuntamente se relacionan con datos cronológicos para su precisión SINGARASUBRAMANIAN et al 2006;MCFADGEN & GOFF 2007;GOTO et al 2010b). Esta complejidad de análisis se gestaría debido a que estos eventos de alta energía involucran varios procesos en su incidencia en la costa, alterando el comportamiento geomorfológico y sedimentológico en unidades morfológicas costeras como es el caso de la playa, siendo valorable toda información extraíble de estas alteraciones post evento.…”

RESUMENMediante una exhaustiva revisión bibliográfi ca, se aborda la caracterización de los depósitos de tsunami históricos y de paleotsunamis a nivel mundial en función de la geomorfología de playas, tomán-dose en consideración los métodos, técnicas y criterios utilizados en su análisis. Tales experiencias demandan de una sistematización y conceptualización que favorezcan dar respuestas a dónde y cómo determinar áreas de depósitos de tsunami pasados para esta unidad morfológica. Este análisis permitió detectar factores determinantes de esta unidad litoral en los procesos de alta energía de los tsunamis, los impactos, además de la importancia de la playa como fuente de investigación de eventos recientes.Palabras Clave: Depósitos de Tsunami, geomorfología litoral, distribución mundial. Theoretical and methodological bases for analysis of tsunami deposits of sandy beaches ABSTRACTThrough extensive literature review deals with the characterization of historic tsunami deposits and global paleotsunamis depending on the geomorphology of beaches, taking into account the methods, techniques and criteria used in their analysis. Such experiences require a conceptualization that encourage systematization and give answers to where and how to identify areas of past tsunami deposits for this morphological unit. Analysis allowed detection of determinants of the coastal drive in high-energy processes of tsunamis, impacts, and the importance of the beach as a research of recent events.
