Typical eruption style:
Explosive activity. In addition, at least during the past +-30 years near-continuous effusion and mildly explosive eruption of natrocarbonatite lava from vents inside the crater, sometimes overflowing over the rim, is taking place.

View into the crater of Ol Doinyo Lengai volcano (photo: Gian Schachenmann)
The volcano continues to be active, and produce natrocarbonatite lava that slowly fills up the crater. A small cone of natrocarbonatite lava is forming on the western side of Lengai's crater, which formed in 2008 during a series of violent explosions that destroyed the former bizarre crater terrace filling the north crater, famous for the bizarre "hornitos" of white and gray lava. ...more

Spattering and lava flows of carbonatite lava inside the deep summit crater of Lengai have been recently observed by climbers. The crater which formed during explosive activity in 2008 is gradually being filled by spatter cones and small lava flows.

Our friend Michael Dalton-Smith flew over Lengai 10 Oct 2010 and snapped a few shots of the crater. There were some recent small lava flows inside the new crater. Also there we signs that new cone has had some more minor collapses on the inside. He could not tell 100%, but there looks like a small lava lake. ...more

Over the past three weeks, Lengai has quietened down significantly. Observers report a complete pause in activity lasting about two weeks, and then resuming of relatively small ash eruptions. A thermal anomaly is still visibile on satellite date in the crater of the ash cone.

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. ...more

The VAAC reported an ash plume from Ol Doinyo Lengai was rising to an altitude of 11.6 km at 15 February. ...more

The activity at Lengai seems to be increasing. In the past two weeks, explosions have ejected ash plumes rising several kilometers. On 15 Feb., Dutch pilots observed and photographed an eruption plume rising to estimated 12 km (36,000 ft).

Typical ash eruption from the new ash cone in the N crater
A small group from VolcanoDiscovery, local mountain guides and partners stayed near and on Lengai volcano during 17-21 January. During this period, Lengai continued to erupt ash to several 100 meters above the new ash cone during phases lasting several hours alternating with periods of quiet when only a weak plume of very fine gray ash and gas was issuing out of the new ash cone. ...more

Based on information from the Tanzania MVO, the Toulouse VAAC reported that Ol Doinyo Lengai erupted on 7 November and remained active. According to Frederick Belton's website, an observer saw a "smoke" plume rise to an altitude of 3.2-3.5 km (10,500-11,500 ft) a.s.l. and drift WSW towards the Gol Mountains on 10 November.
