St. Kitts - Geothermal Activity

Active low temperature (up to 100oC) fumaroles are present in the crater of Mt. Liamuiga. Cracks within the limestone at the base of Brimstone Hill emit a strong smell of sulphur but no steaming was observed by Simpson and Shepherd (2002). The temperatures within these cracks were only slightly elevated and sulphur crystals line the cracks locally. A strong smell of sulphur is also present along the coastline below Brimstone Hill. No obvious source for the smell was observed; however, discoloration of rocks near the shore may indicate that the vents are located just offshore and that diffuse venting occurs through the ground along the coastline.


Brimstone Hill National Park. Strong sulphur smells and discolored rocks in the vicinity of this andesite dome suggests that there may be fumarolic vents located at the base of the dome and along the coastline to the west (left of the photograph).
