The canyon

  • The canyon, known as Eratosthenesfor the underwater mountain it is near, dates back to the Messinian Event that transpired about 5.5 million years ago.
  • The canyon is about 10 km wide and 500 m deep and was buried at the beginning of the Messinian period before the deposition of the salt layer.
  • It was created when the level of the Mediterranean Sea decreased at the same time there was a rise in the salinity of the water, which apparently created gravity currents or dense solutions that caused the destabilization of the submarine slopes and subsidence of the seabed.
  • According to the institute in a broader aspect this work reveals the environmental conditions of high salinity and lower sea level in the deep Mediterranean basin at the beginning of the Messinian event.
  • Also known as the Messinian salinity crisis, the Messinian event was a geological event during which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation.


  • Cyprus is an island country located in the eastern Mediterranean Sea, north of the Sinai Peninsula, south of the Anatolian Peninsula, and west of the Levant.
