Caption: Pyroclastic flow on Mount Sinabung volcano. Night-time time-lapse footage of a lava dome failure leading to a pyroclastic flow and induced lightning on Mount Sinabung (2460 metres), an andesitic stratovolcano in Sumatra, Indonesia. A pyroclastic flow (also known as a nuee ardente or glowing avalanche) is a highly destructive event that consists of a very hot cloud of volcanic ash, dust and gases. The cloud cascades down the side of the volcano, supported by searingly hot gases that can reach 800 degrees Celsius. The cloud can reach speeds in excess of 160 kilometres per hour. Inactive for over a thousand years, this volcano briefly awakened in 2010, after which a larger eruption occurred from 2014 onwards. This footage was obtained during a phase of intense dome growth and disintegration from 12-18 February 2014.
