Afro-Arabian Rift System

E229848

geological structure tectonic rift system

The Afro-Arabian Rift System is a major tectonic rift complex separating Africa from the Arabian Peninsula, characterized by active faulting, volcanism, and the formation of features such as the Red Sea and surrounding gulfs.

How this entity was disambiguated

This entity first appeared as the object of triple T2037727 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A. East African Rift
The East African Rift is a major tectonic rift system in eastern Africa where the African Plate is splitting into separate plates, creating a chain of rift valleys, volcanoes, and lakes.
B. Malawi Rift
The Malawi Rift is a major segment of the East African Rift system characterized by active tectonics, deep basins, and the long, narrow Lake Malawi.
C. Somali Plate
The Somali Plate is a minor tectonic plate in East Africa that is slowly rifting away from the main African Plate along the East African Rift system.
D. Jordan Rift Valley
The Jordan Rift Valley is a major geological depression in the Middle East forming part of the Great Rift Valley, characterized by its below-sea-level basin that includes the Dead Sea and the Jordan River.
E. Northeast Rift Zone
The Northeast Rift Zone is a major volcanic fissure system on Mauna Loa’s flank from which many of the volcano’s historic lava flows have erupted.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
