Ol Doinyo Lengai volcano (Tanzania) - ash eruptions (18 January 2008)
During 17-19 January, we managed to stay on top of Lengai with a small group. During much of the time, the summit was in clouds, but on 18 January, the afternoon proved to be clear and Lengai started a phase of ash eruptions lasting from around 4pm to 8pm. A detailed report about the expedition and Lengai's acitivity in the time between 17 and 21 January can be found here.
