Oldoinyo Lengai Trekking
Oldoinyo Lengai” means “The Mountain of God” in the Maasai language. The summit of this strato-volcano is 2962 metres above sea level, and affords direct views into the caldera of Tanzania’s only officially-certified active volcano, and the world’s only carbonatite volcano; records of eruptions have been maintained since 1883, the largest of which deposited ash 100 kilometres away in Loliondo on the Kenyan border to the north west.
Recent Seismic Activity
Recent volcanic activity began on 12th July 2007 with daily tremors in Kenya and Tanzania, the strongest of which measured 6.0 on the Richter scale. The mountain finally erupted on September 4, 2007, sending a plume of ash and steam at least 18 kilometres downwind and covering the north and west flanks in fresh lava flows. The eruption continued intermittently into 2008, with a major outburst taking place on March 5 2008, and smaller eruptions on 8 and 17 April 2008; activity continued until late August 2008. A visit to the summit in September 2008 discovered lava emission from two vents in the floor of the new crater; by April 2009 this activity appeared to have ceased, but eruptions occurred again in October 2010.
