The Soufrière Hills volcano is an active stratovolcano on the Caribbean island of Montserrat. After being dormant for a long time, it became active in 1995. It has been active since then. Because of its eruptions, no one can live on the south half of Montserrat. The capital city, Plymouth, was destroyed. About two thirds of the population had to leave Montserrat. It had been showing signs of erupting for a long time before it did. When it did erupt, 19 out of the 23 people that remained burned to death because of the pyroclastic flow which was 400 °C (752 °F).
