Natural hazards
flash floods are a constant threat; destructive hurricanes can be expected during the late summer months volcanism: Dominica lies in the middle of the volcanic-island arc of the Lesser Antilles that extends from the island of Saba in the north to Grenada in the south; of the 16 volcanoes that make up this arc, five are located on Dominica, more than any other island in the Caribbean: Morne aux Diables (861 m), Morne Diablotins (1,430 m), Morne Trois Pitons (1,387 m), Watt Mountain (1,224 m), which last erupted in 1997, and Morne Plat Pays (940 m); the two best-known volcanic features on Dominica, the Valley of Desolation and the Boiling Lake thermal areas, lie on the flanks of Watt Mountain, and both are popular tourist destinations
Geography - note
known as "The Nature Island of the Caribbean" due to its lush and varied flora and fauna, which are protected by an extensive natural park system; the most mountainous of the Lesser Antilles, its volcanic peaks are cones of lava craters and include Boiling Lake, the second-largest thermally active lake in the world
Natural resources
timber, hydropower, arable land
Area - comparative
slightly more than four times the size of Washington, D.C.

Population distribution
population is mostly clustered along the coast, with roughly a third living in the parish of St. George, in or around the capital of Roseau; the volcanic interior is sparsely populated
