Nuee Ardente
Nuee Ardente :
A French term ("glowing cloud") that was first used to describe the deadly 1902 eruption of Montagne Pelée (Island of Martinique) that devastated the port city of St. Pierre (Lacroix, 1904). A nuée ardente is a density current consisting of hot pyroclastic fragments, volcanic gases, and air that flows at high speed from the crater region of a volcano - generally associated with the collapse of an eruption column or unstable lava dome. See glowing avalanche, pyroclastic flow, and pyroclastic surge
