The Observatoire Volcanologique de Goma (OVG) reported that during 1-31 July the level Nyiragongo?s lava lake had dropped, making it not visible in the daytime. Incandescence from the lake continued to be visible at night. Activity also declined at a small eruptive cone that formed in the crater in 2014.
