Similarly to previous phases, new natrocarbonatite lava is being erupted from vents at the bottom of the new crater. If this activity continues, it might once again fill the crater.

Ol Doinyo Lengai volcano (Tanzania): active crater and natrocarbonatite lava in early Dec 2017

The volcano continues to slowly erupt natrocarbonatite lava inside the deep pit crater of the 2007-08 cinder cone which occupies the active northern crater of Lengai volcano. We present a selection of aerial photos taken a few days ago by our friend Gian Schachenmann. ... Read all

Ol Doinyo Lengai volcano (Tanzania): natrocarbonatite lava activity inside the summit crater

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. ...

An explosive eruption from Tanzania's Ol Doinyo volcano in 1966.  Explosive activity began in August 1966, near the end of an eruption beginning in 1960 that consisted of quiet emission of lava flows in the summit crater.  Ash deposits from previous eruptions whiten the volcano's slopes like snow. (Photo by Gordon Davies, 1966 / courtesy of Celia Nyamweru, Kenyatta University).
