Gelai Volcano also known as Gelai (Mlima Gelai, in Swahili) stands at 2,942 metres (9,652 ft) tall[1] and is located in Longido District of Arusha Region in Tanzania. The volcano is located in the geographic area of the Crater Highlands and is a shield volcano that last erupted in the pleistocene.[2] It is at the southeastern edge of Lake Natron in the East African Rift. Gelai is the third most prominent peak in Arusha Region and is the 13th highest peak in Arusha region.[3] Volcanic activity on Gelai dates to less than one million years ago.[4] A number of earthquakes occurred in the area in the summer of 2007. Associated with the largest earthquake on 17 July, a NNE-oriented fracture or narrow graben formed on the southern flank of Gelai. The fracture may be associated with the intrusion of a narrow dike at a depth of around 4,000 metres (13,000 ft).[4]
