Nuée Ardente - John Seach

(Glowing Cloud)

A glowing cloud or Nuée Ardente is a gas generated eruptive phenomenon consisting of two parts.

1) glowing avalanche (lower denser part)
2) Lighter fraction of volcanic gases, ash, and dust which cauliflower upwards.

A nuée ardente consists of two parts where a pyroclastic flow only relates to the lower glowing avalanche.
