PORT OF SPAIN, Trinidad, CMC—The Seismic Research Centre (SRC) at the St. Augustine campus of the University of the West Indies (UWI) says the water levels at Dominica’s Boiling Lake have changed significantly in recent days. It says this phenomenon has occurred several times since 1876.
“The most recent period instability was observed in December 2023, and in the following months, guides and Forestry officials have reported changes in the lake levels, with the latest occurring during March,” the SRC said on its Facebook page.
It said on March 29, the lake was observed to experience a significant drop in water levels once again when there was little to no water observed in the lake.”
However, the SRC said that the observed changes in water levels and activity at the Boiling Lake “are not necessarily related to increased volcanic activity in the area,” adding that “during these episodes, harmful gases such as carbon dioxide can be released, and small steam explosions may also occur.
“This most recent cessation of geothermal activity at the lake may be indicative of blockages of underlying vents, which feed into the lake and is of concern as clearing of this blockage can occur without warning.”
The SRC said that it will continue to monitor the situation together with the Office of Disaster Management in Dominica.
The Boiling Lake is a flooded fumarole in Morne Trois Pitons National Park, a World Heritage Site. Located 6.5 miles east of Dominica’s capital, Roseau, it is filled with bubbling greyish-blue water that is usually enveloped in a cloud of vapor.
The Boiling Lake is approximately 200 to 250 feet across and is the second-largest hot lake in the world after Frying Pan Lake, located in Waimangu Valley near Rotorua, New Zealand.
