Details for: Watt, Morne
Fumarolic clouds mark the Valley of Desolation and Boiling Lake thermal areas, NE of Morne Watt (Watt Mountain) volcano in SE Dominica. The Valley of Desolation and the Boiling Lake are major tourist attractions within the national park east of Roseau. A major eruption from Morne Watt produced pyroclastic flows about 930 years ago. The only historical eruptions on the island of Dominica were a moderately large phreatic explosion at the Valley of Desolation thermal area in 1880 and a smaller phreatic explosion in July 1997.
