Harrat Rahat
Ḥarrat Rahāṭ[1] (Arabic: حَرَّة رَهَاط) is a volcanic lava field in the Hejazi region of Saudi Arabia. In 1256 CE, a 0.5 km3 (0.12 cu mi) lava flow erupted from six aligned scoria cones, and traveled 23 km (14 mi) to within 4 km (2.5 mi) of the Islamic holy city of Medina; this was its last eruption. There were earlier eruptions, such as in 641 CE, which made finger-like flows to the east of the 1256 CE flow.[2] It is the biggest lava field in Saudi Arabia. Nearby is Al Wahbah crater.
