Saint Vincent contains La Soufrière, the highest peak in Saint Vincent and the Grenadines.
La Soufrière is an active stratovolcano at the northern end of Saint Vincent. Its summit reaches 1,234 metres, making it the highest point in the country. The volcano has produced explosive eruptions and pyroclastic flows during several historical events.
A major eruption began in December 2020 and continued into April 2021. The activity forced large-scale evacuations and caused serious damage in northern Saint Vincent, including ashfall and destruction of vegetation and buildings.
The name La Soufrière comes from a French term associated with sulfur-producing volcanic vents. Several Caribbean volcanoes share similar names, including La Soufrière on Guadeloupe, so the island specified in the question is important.
