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).

If this activity continues, it might once again fill the crater.
