La Soufrière South Crater (Basse-Terre, Guadeloupe)

La Soufriere volcano, Lesser Antilles

Volcano: La Soufrière (see La Soufrière at the Smithsonian Institution website in a new tab)
Type: Volcanic Plume
Description: La Soufrière volcano in Guadeloupe (Lesser Antilles arc) is the youngest volcanic relief topping a far larger (~16 km3) and long-lived active volcanic complex, the Grande Découverte–Soufrière composite volcano, located in the southern part of Basse Terre island. It consists of an ~0.05 km3 lava dome that was emplaced during the final stage of the last magmatic eruption in 1530 AD. Since then, intense hydrothermal activity (fumaroles, solfataras, hot springs) has persisted on and around the lava dome, and six series of phreatic eruptions happened, the most recent one in 1976–1977. This activity represents the surface expression of a well-developed hydrothermal system that receives heat and gas fromamagma reservoir probably confined at 6–7 km depth beneath the summit.
