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.
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

The Hellenic subduction zone (HSZ) is the convergent boundary between the African plate and the Aegean Sea plate, where oceanic crust of the African is being subducted north–northeastwards beneath the Aegean.
South of Crete is the Hellenic Trench, between 2,000 m (6,600 ft) and 4,000 m (13,000 ft) deep. North of eastern Crete are the two main deeps of the Sea of Crete, about 2,200 m (7,200 ft) and 2,500 m (8,200 ft) deep. They border the Cycladic Plateau of about 250 m (820 ft) maximum depth.
A combined diagram of the Aegean and Anatolian plates. The southern margin of the Hellenic arc is shown, which is the trend line of the faults separating the arc and the Hellenic Trench. The body of the arc is the chain called the outer Hellenides, which includes west Peloponnesus, Crete, Rhodes, southwestern Turkey, and all the islands between.
The supergiant amphipod (Alicella gigantea) is found in the Hadal zone (collected from Japan Trench, 2022) Marine life decreases with depth, both in abundance and biomass , but there is a wide range of metazoan organisms in the hadal zone, mostly benthos , including fish , sea cucumber , bristle worms , bivalves , isopods , sea anemones ...
The earthquake was the result of normal faulting at a shallow crustal depth within the Aegean Sea plate in the eastern Aegean Sea, about 250 km (160 mi) north of the closest plate boundary, the Hellenic Trench, where the African plate moves north at a rate of approximately 10 mm (0.39 in)/yr with respect to the Eurasian plate.
