Dust devils on Mount Sinabung volcano

Videonummer 12329070
Dust devils on Mount Sinabung volcano. Footage of mini-tornadoes (dust devils) over a hot pyroclastic flow deposit field on Mount Sinabung, a stratovolcano in 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. Mount Sinabung (2460 metres) is an andesitic stratovolcano in Sumatra, Indonesia. 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.
