Ol Doinyo Lengai volcano (Tanzania), eruption news: powerful ash eruptions

Tue, 11 Mar 2008, 11:06
11:06 AM |
Lengai's activity has been continuing to increase. Over the past days, several ash eruptions have produced plumes up to more than 10km height, the largest one possibly being on 4 March rising to about 14 km, as evident from satellite data, observations by passing aircraft and spectacular photos taken from the ground posted on Fred Belton's website.
Possibly, some of the eruptions have also produced pyroclastic flows travelling part way down the steel flanks of the mountain. It should be noted that visiting Lengai, even its lower flanks must be considered EXTREMELY dangerous. There are no safe observation spots nearby, particularly as the topography of the mountain puts the surrounding flat areas into a high risk zone of pyroclastic flows.
