Glow from nearby (but hidden) lava pooling somewhere beneath the collapse pit in Lengai's crater (taken on evening of 31 Jan 07).
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.
In addition to the loud sound of revolving lava underground, a constant, deep rumbling could be heard from the ground, resembling the sounds of very distant thundering. It was strongest in the NW area of the crater between the collapse pit and the fissure vents of the March 2006 lava flow. We think it might be an audible form of volcanic tremor more or less directly related to a magma volume still inside the same dike. When talking to local guides, they believe that a new, large-volume effusive eruption of lava from a similar area as in March 2006 might occur in the near future.
