From June 22 to September 15, 2014, fountaining activity appeared in the pit crater of the Nyamulagira's summit caldera. This activity was followed, on November 1, 2014, by the emergence of a small long-lived lava lake at depth, in the pit crater. This video shows images taken on July 1 and 5, 2014, during helicopter flights and field work in the caldera.
