Ol Doinyo Lengai volcano (Tanzania), activity update: ash fall, closure of Moiravo Tented Lodge
It seems that the eruption at Lengai is indeed a major event and that explosive activity has taken or is taking place in addition to lava flows and probably, bush fires. According to local sources from the nearby Moivaro - Lake Natron Camp, Lengai first erupted at midnight and at 6 am on 4 September. A pilot reported ash rising to 20,000 ft (ca. 6 km). Ashfall was reported from Engaresero Village, but there are no reports on injuries or fatalities. The highly regarded Moivaro Tented Lodge near Lake Natron has been temporarily evacuated.
Scientists including Matthieu Kervyn warn to approach the volcano as it could develop into a major explosive, crater-clearing eruption such as in 1966-67. Extremely dangerous pyroclastic flows could be and are likely to be associated if the eruption escalates.
