Dominica, West Indies

Dominica is part of the Lesser Antilles island arc that marks a convergent plate tectonic boundary between the Caribbean and Atlantic plates. The island of Dominica consists mostly of breccias, domes, pyroclastic flows, and lavas derived and erupted from at least seven volcanic centers. There have been no historic eruptions on the island. However, in 1880, there was a steam blast in the Valley of Desolation. Four solfataric areas, including the famous Boiling Lake, remain active.
