“…Overall, the marine origin of a boulder, in combination with the application of hydrodynamic equations and a geochronology that allows to link the high energy event to a historical or prehistorical tsunami may be the key criteria to attribute such a deposit to a tsunami event. Despite all uncertainties, much research has also taken place after modern events, providing valuable information for the identification of palaeotsunamis on coastal landscapes [11,21,92,93]. In fact, post-tsunami surveys of recent events such as the Indian Ocean Tsunami 2004 [1] or the 2011 Tōhoku-oki tsunami in Japan [3], have provided significant new insights to better understand the nature of sedimentological, geochemical and paleontological features, following a tsunami event.…”

“…Along the Greek coastal zone, field data ascribed to tsunami events are primarily represented by (a) boulders accumulations [81,84,[101][102][103][104], and (b) sediment layers in cores, archaeological excavations [105,106], or exposed on coastal cliff surfaces [107] (Figure 4). Despite all uncertainties, much research has also taken place after modern events, providing valuable information for the identification of palaeotsunamis on coastal landscapes [11,21,92,93].

“…Following the 2011 T ōhoku-oki tsunami, field survey research included geochemical studies [94], inundation mapping and modelling [95], tsunami deposit characteristics and spatial variability [96,97], aerial video analysis [98]. It was found that tsunami deposits generally lacked a significant marine signature [99], which, in combination with numerical modeling, suggests that the bathymetry influences the processes of onshore marine sediment transport [11], while sediments derived from the beach, sand dunes, lagoons and inland soils [10]. The thickness of sand and muddy deposits after the event reached about 30 cm, while it was smaller inland [10].…”

“…Recent events, such as the Indian Ocean Tsunami 2004 [1], Hurricane Katrina 2005 [2], or the 2011 T ōhoku-oki tsunami in Japan [3], have highlighted the impact marine and coastal processes may have on coastal populations. During the last decades, the catastrophic impact of tsunamis has prompted a significant shift in public awareness and research on coastal risks changes globally [4][5][6][7][8][9][10][11].…”

Tsunamis in the Greek Region: An Overview of Geological and Geomorphological Evidence

The Greek region is known as one of the most seismically and tectonically active areas and it has been struck by some devastating tsunamis, with the most prominent one being the 365 AD event. During the past decade significant research efforts have been made in search of geological and geomorphological evidence of palaeotsunamis along the Greek coasts, primarily through the examination of sediment corings (72% of studies) and secondarily through boulders (i.e., 18%). The published data show that some deposits have been correlated with well-known events such as 365 AD, 1303 AD, the Minoan Santorini Eruption and the 1956 Amorgos earthquake and tsunami, while coastal studies from western Greece have also reported up to five tsunami events, dating as far back as the 6th millennium BC. Although the Ionian Islands, Peloponnese and Crete has been significantly studied, in the Aegean region research efforts are still scarce. Recent events such as the 1956 earthquake and tsunami and the 2020 Samos earthquake and tsunami highlight the need for further studies in this region, to better assess the impact of past events and for improving our knowledge of tsunami history. As Greece is amongst the most seismically active regions globally and has suffered from devastating tsunamis in the past, the identification of tsunami prone areas is essential not only for the scientific community but also for public authorities to design appropriate mitigation measures and prevent tsunami losses in the future.

Palaeo-Tsunami Events on the Coasts of Cyprus

et al. 2022

View full text Add to dashboard Cite

Cyprus has a long history of tsunami activity, as described in archaeological and geological records. Although the study area has experienced tsunamis in the past and constitutes an area threatened by this hazard both from the Cyprean arc and from the neighboring Hellenic arc, field research on tsunami evidence on the coastal zone of Cyprus still remains scarce. It is clear from the literature that large boulder accumulations are an important feature along the coasts of Cyprus, testifying to extreme events. A detailed field survey revealed that at various locations cited in the literature as hosting geomorphological evidence of past tsunamis, no such evidence was identified. It is likely that the high touristic activity that has been occurring on the coasts of Cyprus during the last 20 years may have affected tsunami indicators such as boulder accumulations. Tsunamis are unpredictable and infrequent but potentially large-impact natural disasters. The latest strong tsunami that caused damage to the Cypriot coast was centuries ago, when the population and economic growth and development at the Cypriot shoreline did not exist. Today, the coastal zone hosts a higher population as well as increasing touristic activity, highlighting the need for better preparedness, awareness raising and for tsunami-related risk reduction.
