About
Gelai Volcano also known as Gelai (Swahili: Mlima Gelai) stands at 2,948 metres (9,672 ft) tall 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. 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. Volcanic activity on Gelai dates to less than one million years ago. 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).
