According to news reports, an eruption began at Ol Doinyo Lengai around 19 July, forcing villagers living near the volcano to evacuate. An article stated that, "...more than 1,500 people, most of them Maasai families, vacated their homes in Ngaresero, Orbalal and Nayobi villages following the tremors that triggered the volcanic eruption."

During our latest expedition to the active crater of Lengai volcano from early 31 Jan - 2 February 2007, no eruption of natrocarbonatite lava occured from the summit vents. According to local Maassai guides, the central area of the crater with the large collapse pit near the tall hornito T49b had not seen significant changes since last summer. From an open vent in the NE corner at the bottom of the pit at the base of the hornito, loud washing-machine like sounds of boiling lava was audible all the time. A large pool of lava must be found somewhere at very shallow depths in some caverns beneath that area. This assumption is confirmed by the glow of lava that was clearly visible one night from a second, smaller vent located about 30 m south of the large vent in the base of the collapse pit. One guide confirmed he had seen spattering of lava from this vent some two weeks earlier. Read all
