On May 8, 1902, Mount Pelée on the island of Martinique produced a pyroclastic flow — a ground-hugging cloud of superheated gas and rock fragments traveling at hurricane speed — that struck the port city of Saint-Pierre at approximately 8:02 a.m. The eruption killed an estimated 28,000 to 30,000 people within minutes, destroying the city and leaving only two known survivors within its limits. The disaster led to the scientific classification of pelean-type eruptions.
