Since 80 My, the eastern Mediterranean basin has been subjected to a complex evolution, controlled by the ongoing convergence between African and Eurasian plates (fig. 1). One of the consequences of this specific kinematics is the formation, within the Ionian and Levantine basins, of the Mediterranean Ridge, an atypical tectono-sedimentary...

The SEAHELLARC project, supported by the European Commission, aimed at evaluating and computing seismic hazard and risk, as well as modelling tsunamis for the town of Pylos, in the western Peloponnese and neighboring region. This paper describes the main scopes and results of the project.

Regional multichannel seismic reflection (MCS) profiles across the Egyptian continental slope, offshore the Nile delta, were recorded during the MEDISIS survey (conducted in 2002 on board the R/V Nadir). The results of this survey allow an interpretation of the overall structure and evolution of this passive continental margin. The MCS data...

Debrites with different volumes, depositional periods and setting are observed in the Nile deep-sea fan system. Here we present debrites from four late Quaternary environments: (i) within the Rosetta submarine channel at 1700 m; (ii) within small basins created by salt tectonics in the Eastern Province at 1300 m; (iii) on the open slope outside...

Although there is a common agreement on the importance of conservation of Mediterranean submarine canyons amongst international organizations, their governance is complex: the canyons' extension covers waters and seabeds under various types of jurisdictions (territorial waters, Fisheries Protection Zone, Ecological Protection Zone, including...

Funded by the EEC Sixth Framework Program, the SEAHELLARC project was aimed to evaluate, and better understand the causes, of the various natural geohazards (chiefly earthquakes and tsunamis), which frequently affect the western Peloponnese area and particularly its coastal domain; this region is one of the most ...

Off northwest Libya the Cyrenaica foreland basin domain and its Pan-African continental crust, which constitute the African promontory, are overthrusted by the Mediterranean Ridge Complex. The thrust belt contact and its seismic stratigraphy have been analysed using pre-stack depth-migrated multichannel seismic (MCS) lines recorded during the...

The Florence Ridge, part of the western Cyprus arc, is a compressional relief that was eroded during the Messinian salinity crisis while deposition of salt occurred North (Antalya basin) and South (Herodotus abyssal plain). In order to better assess the impact of salt-tectonics in the Florence Ridge region deformations, we conducted a...

Deep-sea fans are favoured settings for the formation of gas hydrates, due to high sedimentation rates and organic matter content that promote the upwelling of methane-rich fluids. Gas hydrates have not been sampled on the Nile fan, but geophysical evidence of their presence is known to the Egyptian hydrocarbon industry. Here we use academic...

The Florence Rise is a submarine feature extending from the island of Cyprus in the southeast to the Anaximander Mountains which form the northwestern end of the Cyprus Arc south of western Turkey. The eastern Florence Rise includes a topographic high near Cyprus while its central domain displays relatively low relief. Most of the major...

In the Eastern Mediterranean, offshore Egypt, the Nile continental margin is characterized by a large deep water turbiditic system known as the Nile Deep Sea Fan. This post-Miocene terrigenous construction covers an approximately 10 km-thick sedimentary pile, including 1–3 km of Messinian salt layers. Systematically collected swath bathymetric...

This paper presents an overview of the evolution of the Nile deep-sea turbidite system during the last 200 kyr, over a series of glacial to interglacial cycles. Six individual deep-sea fans were identified from an extensive field data set. Each fan comprises a canyon, channel system and terminal lobes. Two of these fan systems were possibly...

A large-scale mass-transport deposit (MTD) called Sl6 was recognized on the upper slope of the western Nile margin, downslope from of a 30 km-long scarp located along the outer shelf. Regional mapping indicated that this MTD extends on nearly 505 km2 and involved about 14 km3 of Pleistocene-Holocene sediment. Sl6 was triggered between 10 and 9...

Based on an unusual data set comprises bathymetric data, backscatter imagery, seismic-reflection and Chirp profiles, and sediment cores, the Late Quaternary lobe at the mouth of the youngest turbidite channel off the western Nile deep-sea fan was investigated. The large-scale construction of the lobe through time and space is mainly controlled...

Voluminous mass-transport deposits (MTD) have been identified on seismic profiles across the central Nile Deep-Sea Fan (NDSF). The youngest MTDs are buried under 30-100 m of well-stratified slope deposits that, in water depths of 1,800-2,600 m, are characterized by undulating reflectors correlated with slope-parallel seabed ridges and troughs....
