La Soufrière

Soufriere St. Vincent

Estratovolcán · Saint Vincent and the Grenadines · 1220 m

Soufrière St. Vincent volcano forms the northern end of the island of St. Vincent. The 1178-m-high stratovolcano, seen here from off the west coast, has a broad summit. The peak at the left, the volcano's high point, is the NW rim of a large crater created by a massive volcanic landslide. The present-day, 1.6-km-wide summit crater truncates a cone (forming the flat-topped area across the saddle to the right) that was constructed within the earlier crater. Several powerful explosive eruptions have occurred in historical time since 1718.

Resumen geológico

Soufrière St. Vincent is the northernmost and youngest volcano on St. Vincent Island. The NE rim of the 1.6-km wide summit crater is cut by a crater formed in 1812. The crater itself lies on the SW margin of a larger 2.2-km-wide caldera, which is breached widely to the SW as a result of slope failure. Frequent explosive eruptions after about 4,300 years ago produced pyroclastic deposits of the Yellow Tephra Formation, which cover much of the island. The first historical eruption took place in 1718; it and the 1812 eruption produced major explosions. Much of the northern end of the island was devastated by a major eruption in 1902 that coincided with the catastrophic Mont Pelée eruption on Martinique. A lava dome was emplaced in the summit crater in 1971 during a strictly effusive eruption, forming an island within a lake that filled the crater. A series of explosive eruptions in 1979 destroyed the 1971 dome and ejected the lake; a new dome was then built.
