An island still being built by its volcanoes

Dominica covers 750 square kilometers and holds nine potentially active volcanic centers, the only island in the Eastern Caribbean with more than one volcano still considered live. Morne Diablotins rises to 1,447 meters. Inside Morne Trois Pitons National Park, the Valley of Desolation vents fumaroles at close to boiling point, and Boiling Lake, roughly 60 meters across, is a flooded fumarole rather than a crater. Guadeloupe lies 48 kilometers north, Martinique 40 kilometers south.

More on Boiling Lake

It is the second largest feature of its kind on record, after Frying Pan Lake in New Zealand. The water sits about 15 meters deep and hovers between 80 and 90 degrees Celsius at the rim, hotter at the churning center. Its level has risen and fallen unpredictably since observers began noting changes in 1876, occasionally draining almost entirely before refilling.
