Arabian Plate
  (Redirected from Arabian plate)
Not to be confused with Arabian Peninsula.
The Arabian Plate is a minor tectonic plate in the northern and eastern hemispheres.
Arabian Plate
Approximate area5,000,000 km2[1]
Speed115–20 mm/year
FeaturesArabian Peninsula, Gulf of Aden, Indian Ocean, Persian Gulf, Red Sea
1Relative to the African Plate
It is one of three continental plates (along with the African and Indian plates) that have been moving northward in recent geological history and colliding with the Eurasian Plate. This is resulting in a mingling of plate pieces and mountain ranges extending in the west from the Pyrenees, crossing Southern Europe to Iran, forming the Alborz and the Zagros Mountains, to the Himalayas and ranges of Southeast Asia.[2]
The Arabian Plate is the most common designation of the region, although it is also sometimes referred to as the Arab Plate.[3]
Eurasian, Anatolian, and Arabian (purple coloring) plates
The Arabian Plate consists mostly of the Arabian Peninsula; it extends westward at the Sinai Peninsula and the Red Sea and northward to the Levant. The plate borders are:
The Arabian Plate was part of the African Plate during much of the Phanerozoic Eon (​Paleozoic​–​Cenozoic​), until the Oligocene Epoch of the Cenozoic Era. Red Sea rifting began in the Eocene, but the separation of Africa and Arabia occurred approximately 25 million years ago in the Oligocene, and since then the Arabian Plate has been slowly moving toward the Eurasian Plate.[5] The opening of the Red Sea rift led to extensive volcanic activity. There are large volcanic fields called the Older Harrats, such as Harrat Khaybar and Harrat Rahat, cover large parts of the western Arabian Plate. Some activity still continues especially around Medina,[6] and there are regular eruptions within the Red Sea.[7]
The collision between the Arabian Plate and Eurasia is pushing up the Zagros Mountains of Iran. Because the Arabian Plate and Eurasian Plate collide, many cities are in danger such as those in southeastern Turkey (which is on the Arabian Plate). These dangers include earthquakes, tsunamis, and volcanoes.
Countries and regions
Countries within the plate include entire Arabia (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates, and Yemen), and Djibouti on the Horn of Africa, as well as parts of the Levant (eastern Lebanon[dubious discuss], Jordan, and Syria) and Mesopotamia (Iraq). Regions include parts of Awdal (​Somalia​/​Somaliland​), the Khuzestan Province (Iran), the Southeastern Anatolia Region (Turkey), and the Southern Denkalya Subregion (Eritrea).
