The Hellenic Trench, with the inner South Aegean Volcanic Arc, and the outer non-volcanic Hellenic arc [1]: 34 . The Hellenic Trench (HT) is an oceanic trough located in the forearc of the Hellenic arc, an arcuate archipelago on the southern margin of the Aegean Sea plate, or Aegean Plate, also called Aegea, the basement of the Aegean Sea.
The Hellenic arc or Aegean arc is an arcuate mountain chain of the southern Aegean Sea located on the southern margin of the Aegean Sea plate. Geologically it results from the subduction of the African plate under it along the Hellenic subduction zone. The Hellenic Trench trends parallel to its southern side.
Calypso Deep is the deepest point in the Mediterranean Sea, located in the Hellenic Trench in the Ionian Sea, 62.6 km south-west of Pylos, Greece, with a maximum depth of approximately 5,200 m (17,100 ft). [1] It lies at about
To the south, the Hellenic Trench, as much as 4,000 m (13,000 ft) deep, borders the Hellenic arc, while to the north the Sea of Crete, a deep adjunct of the Aegean Sea, descends as deep as 1,000 m (3,300 ft). In contrast to these deep water environments, the coastal shelf of Crete is shallow and dotted with reefs, making it dangerous for ships.
This indicates that the tsunami of 365 was generated by an earthquake in a steep fault in the Hellenic Trench near Crete. Scientists estimate that such a large uplift is likely to occur only once in 5,000 years; however, the other segments of the fault could slip on a similar scale—and this could happen every 800 years or so.
Rocks of Archean age in Norway are confined to a few 10 km-scale areas within younger metamorphic belts exposed on islands off the west coast of northern Norway and as smaller fragments locally in the Western Gneiss Region in south-central Norway.
The undersea cliff is incised by more than 500 canyons, while landslide occurrence has been inferred from sediment samples collected from the base of the escarpment.The 2012 research on the escarpment closest to Sicily identified 70 submarine landslides as well as black coral reefs, while a 2014 survey focused further south but still on the northern part of the escarpment, especially on the ...
