pelean eruption

A type of volcanic eruption characterized by a ground hugging glowing avalanche (pyroclastic flow) resulting from a mixture of hot volcanic gases, ash, and incandescent lava fragments. Pelean eruptions may occur when pyroclasts are blown out of a central volcanic vent and then collapse onto the earth's surface to form a pyroclastic flow (Tilling, 1985). Pelean eruptions may also occur as a result of the explosive disintegration of a lava dome (as was the case for the lava dome on Mt. Pelee, Martinique in 1902).
