The Soufrière Hills volcano is a stratovolcano located on the British Overseas Territory of Montserrat in the Lesser Antilles island arc of the Caribbean. Its catastrophic eruption in the mid-1990s rendered the southern half of the island an “exclusion zone.” Geographically, the eruption is famous for its massive lava domes and destructive pyroclastic flows that reached the sea. The event significantly changed the island’s geography, creating new coastline through ash deposits. It remains one of the world’s most strictly monitored volcanoes due to its history of sudden, high-intensity eruptions and its impact on human settlement patterns.
