Mount Pelée
Mount Pelée (/pəˈleɪ/; French: Montagne Pelée ""Bald Mountain"") is an active volcano at the northern end of Martinique, an island and French overseas department in the Lesser Antilles island arc of the Caribbean. Its volcanic cone is composed of layers of volcanic ash and hardened lava.The stratovolcano is famous for its eruption in 1902 and the destruction that resulted, dubbed the worst volcanic disaster of the 20th century. The eruption killed about 30,000 people. Most deaths were caused by pyroclastic flows and occurred in the city of Saint-Pierre, which was, at that time, the largest city on the island.Pyroclastic flows completely destroyed St. Pierre, a town of 30,000 people, within minutes of the eruption. The eruption left only two survivors in the direct path of the flows: Louis-Auguste Cyparis survived because he was in a poorly ventilated, dungeon-like jail cell; Léon Compère-Léandre, living on the edge of the city, escaped with severe burns. Havivra Da Ifrile, a young girl, reportedly escaped with injuries during the eruption by taking a small boat to a cave down shore, and was later found adrift two miles (3 km) from the island, unconscious. The event marked the only major volcanic disaster in the history of France and its overseas territories.
