Timelapse footage of the lava lake in the crater of the Mount Nyiragongo volcano, in the Democratic Republic of the Congo. Convection of hot lava from below pushes the cooler and darker lava at the surface to the sides, where it sinks and heats up again. The process is somewhat analogous to the movement of tectonic plates across the surface of the Earth. Active lava lakes such as this are very rare, occurring in only four other volcanoes around the world. Mount Nyiragongo stands 3470 metres tall, and is only around 20 kilometres from the city of Goma, with one million inhabitants. Its lava is unusually fluid, and an eruption in 2002 destroyed some 40% of the city, although there was enough warning to evacuate most inhabitants. Due to the danger it poses, Nyiragongo has been designated a Decade Volcano, worthy of close study due to the threat to inhabited areas. Filmed in January 2011. | |
