West, a left lateral fault boundary with the African Plate called the Dead Sea Transform (DST), and a divergent boundary with the African Plate called the Red Sea Rift which runs the length of the Red Sea;
The Arabian Plate was part of the African Plate during most of the Phanerozoic Eon (Paleozoic–Cenozoic), until the Oligocene Epoch of the Cenozoic Era. The Red Sea rifting began in the Eocene, and the separation of Africa and Arabia occurred approximately 25 million years ago in the Oligocene, and since then the Arabian Plate has been moving toward the Eurasian Plate.[5] The opening of the Red Sea rift led to volcanic activity. There are volcanic fields called the Older Harrats, such as Harrat Khaybar and Harrat Rahat, cover 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, some cities such as those in southeastern Turkey (which is on the Arabian Plate) may undergo earthquakes, tsunamis, and volcanoes.
