A pilot report indicated an eruption of Ol Doinyo Lengai volcano in Tanzania occurred at 8:30 am local time Friday 19th October 2007. An ash plume reached 25,000 ft altitude, and was visible from a distance of 50 miles. The eruption lasted 30 minutes.
The volcano has an impressive cone shape and rises above the plain from Lake Natron. The cone is composed of ash and reaches a maximum slope of 42 deg. Ol Doinyo Lengai Volcano has the coolest lava of any volcano. It erupts at less than 600 deg C.
Most eruptions at the volcano are small. Larger than normal eruptions occurred in 1917 when vegetation was destroyed on the volcano and ashfall caused destruction of grazing land and death of herds of masai cattle. An eruption in 1940-41 lasted for six months and ash fell 100 km from the volcano.
