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.

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).
