Volcanoes of Saudi Arabia are located in the west and northwest of the country.
Harrats are the name given to continental basaltic lava fields of the western Arabian plate. They cover about 180,000 sq km from Yemen in the south to Turkey in the north. This constitutes the Arabian continental alkali basalt province.
The Arabian Harrats differ from the lava fields of east Africa because they are not associated with continental rifts. They occur on uplifted eastern flank of Red Sea, and are similar to basalt fields of eastern Australia.
