The Morne Trois Pitons National Park inward the isle province of Commonwealth of Dominica , inward the Caribbean Area , is an expanse of pregnant volcanic activity. Located inside the boundaries of the park’s nearly vii ,000 hectares are 5 volcanoes , dozens of hot springs in addition to fumaroles in addition to a real large in addition to famous boiling lake.
Dominica's Boiling Lake is genuinely a flooded fumarole , which is an opening or a hole inward the Earth’s crust. It is filled amongst bubbling greyish-blue H2O at temperatures of only about 90°C. The H2O is heated past times hot steam in addition to gases escaping from molten lava below. The surface of the lake is usually enveloped inward a cloud of vapor. The lake is only about 76 meters across , making it the second-largest hot lake inward the populace later on the Frying Pan Lake inward Waimangu Valley close Rotorua , New Zealand.

The lake was laid out sighted inward 1875 past times 2 English linguistic communication gentlemen who were working inward Commonwealth of Dominica at that time. Later that yr , a regime botanist in addition to i of the master copy discoverers were commissioned to investigate this natural phenomenon. They measured the H2O temperature in addition to establish it to hit from 82–92 °C along the edges , but could non mensurate the temperature at the middle where the lake is actively boiling. They estimated the lake to hold upwards nigh sixty meters deep or more.
The lake is fed past times rainfall in addition to 2 modest streams which drain into the area. The H2O in addition to then seeps downwards to the lava in addition to is heated to the boiling point. The lake’s H2O marker keeps fluctuating in addition to the activeness of the lake equally good lowers from fourth dimension to time. The lake had almost disappeared later on a phreatic eruption occurred nearby inward 1880 , in addition to formed a fountain of hot H2O in addition to steam instead. The lake had some other dramatic fluctuation inward 2004-2005 when its marker got lowered past times 10 meters , in addition to and then recovered inward a unmarried day.
Geologists believe that the lake is suspended higher upwards the local H2O tabular array , which explains its rapid draining in addition to refilling. Influenza A virus subtype H5N1 continuous flux of steam or gas generated past times an underlying magmatic intrusion drives H2O upwards into the lake. Influenza A virus subtype H5N1 disturbance to the provide of gas tin terminate displace the lake to drain through the porous connectedness that unremarkably allows steam to rising in addition to oestrus the lake.
