Nyamuragira, like other volcanoes with fast or very fast or constant supply such as Kilauea, Nyiragongo, Erta Ale and Ambrym, goes through cycles of summit lava lake fillings and flank intrusions which drain out their lava lakes. With the central magma conduit once again visible as a convective open conduit lava lake, the volcano has entered a ”shield lava lake phase” fillings its summit caldera. Nyamuragira’s new lava lake is roughly bean shaped with rising lava apparently welling up in the southern part of the lake and sinking down back in into the conduit in the northern part of the lava lake as a part of its natural convection cycle.
