Details for: Soufriere Guadeloupe
La Soufrière volcano, the highest in the West Indies, is a complex stratovolcano that dominates the southern end of Basse-Terre, the western half of the butterfly-shaped island of Guadeloupe. A steam-and-ash column rises above the summit in this October 1976 view from the NE at Pointe-a-Pitre, on the isthmus connecting the island segments. The peak at the left (above the sailboat), l'Echelle, is a young cinder cone; the summit itself is a 500-year-old lava dome, and remnants of older collapsed volcanoes are located to its right.

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.

Location: La Soufrière Ty fault (View Details at MaGa DB)
Description: In addition to fumarolic emissions, intense diffuse soil degassing has been recognized at the southeastern base of La Soufrière lava dome, in a hydrothermal area aligned on the Ty fault volcano-tectonic structure that cuts the dome.
