“…Similar findings of submerged notches are known from the Croatian coast (Faivre et al, 2011;Marriner et al, 2014). Mastronuzzi et al (2014) even provided geomorphological and sedimentological evidence for a series of tectonic events on Corfu that may be correlated with tsunami impacts reported for comparable time periods from surrounding regions such as Adriatic Italy (Mastronuzzi & Sansó, 2004;Maramai et al, 2007) and Sicily (Barbano, Pirrotta, & Gerardi, 2010;De Martini et al, 2012;Smedile et al, 2011). Concerning tsunamigenic sediments at Corfu itself, Fischer et al (2016a) present geomorphological and microfaunal evidence of multiple paleotsunamis, traces of which were investigated in coastal lagoons along the southwestern and eastern coasts of the island.…”

In this study, the Alkinoos Harbor of ancient Corfu was investigated by means of geomorphological and sedimentological methods in order to reconstruct the ancient harbor's construction, its period of use and spatial extent, and local paleoenvironmental changes. We present sedimentological evidence for the Alkinoos Harbor that shows distinct signs of dredging activities. Although the harbor must have been in use from the Archaic period onwards, a set of paleoenvironmental proxies based on vibracoring, geophysical prospection, electrical conductivity logging, microfaunal studies, and geochemical analyses revealed typical sediments of a closed, protected Roman harbor that was in use between the 1st and 6th century A.D. In addition, sedimentological and microfaunal evidence allowed us to differentiate between different parts of the Roman harbor. In contrast, the pre-Roman harbor and its shipsheds were built on a sandy seashore. Our data revealed two distinct stratigraphic disruptions related to tsunamigenic impact. These paleotsunamis were

“…Considering our findings in vibracores KOR IV and KOR V, it has to be discussed if the observed marker horizons are somehow related to co-seismic uplift movements reported from this part of the island (Mastronuzzi et al, 2014). The following geomorphological and sedimentological arguments clearly speak for a tsunami-related imprint.…”

“…These events are associated with strong earthquakes which have to be considered as potentially tsunamigenic. Recently, Mastronuzzi et al (2014) report on earthquake-related co-seismic events on Corfu in association with relative sea level fluctuations that occurred around 1000 BC, 300 BC and, more recently, around 430 or 1278 AD. These events clearly demonstrate the high neotectonic activity in the area of Corfu during historical times.…”

Abstract. The accumulation of large boulders related to waves generated by either tsunamis or extreme storm events have been observed in different areas of the Mediterranean Sea. Along the eastern low-lying rocky coasts of Malta, five sites with large boulder deposits have been investigated, measured and mapped. These boulders have been detached and moved from the nearshore and the lowest parts of the coast by sea wave action. In the Sicily-Malta channel, heavy storms are common and originate from the NE and NW winds. Conversely, few tsunamis have been recorded in historical documents to have reached the Maltese archipelago.We present a multi-disciplinary study, which aims to define the characteristics of these boulder accumulations, in order to assess the coastal geo-hazard implications triggered by the sheer ability of extreme waves to detach and move large rocky blocks inland.The wave heights required to transport 77 coastal boulders were calculated using various hydrodynamic equations. Particular attention was given to the quantification of the input parameters required in the workings of these equations, such as size, density and distance from the coast. In addition, accelerator mass spectrometry (AMS) 14 C ages were determined from selected samples of marine organisms encrusted on some of the coastal boulders. The combination of the results obtained both by the hydrodynamic equations, which provided values comparable with those observed and measured during the storms, and radiocarbon dating suggests that the majority of the boulders have been detached and moved by intense storm waves. These boulders testify to the existence of a real hazard for the coasts of Malta, i.e. that of very high storm waves, which, during exceptional storms, are able to detach large blocks of volumes exceeding 10 m 3 from the coastal edge and the nearshore bottom, and also to transport them inland. Nevertheless, the occurrence of one or more tsunami events cannot be ruled out, since radiocarbon dating of some marine organisms did reveal ages which may be related to historically known tsunamis in the Mediterranean region, such as the ones in AD 963, 1329, 1693 and 1743.
