Montserrat is a small Caribbean island where a volcanic eruption has devastated the southern region since 1995. The eruption of the Soufriere Hills volcano has forced over half of the island's population to evacuate as the volcano remains active. The eruption is caused by subduction of tectonic plates under Montserrat and has destroyed infrastructure like roads, ports, and airports while covering the landscape in ash. The British government has provided aid to resettle displaced residents but responses have been complicated by the ongoing risks from the still-active volcano.
