What Is a Fumarole?

Except for the crater, fumaroles can be called any pore that can emit gas and steam. Fumaroles are characteristic of the late or declining volcanic activity, so they are often called volcanic fumaroles. After the eruption ceased, fumarole activity often lasted for thousands of years. ^[1]

Fumarole (Latin Fumus, smoke) is the earth's open shell (or any other astronomical body), often near the volcano, releasing vapors and gases such as carbon dioxide, sulfur dioxide, hydrochloric acid and hydrogen.

Fumaroles can occur along tiny cracks or long cracks, in a chaotic string or ground, in

Lakes with fumaroles --- boiling water lakes

The boiling water lake is located in the world cultural heritage of Dominica ----- Mornatroy Pistons National Park, about 10.5 km from the Dominican capital Roseau. The span of the boiling water lake is about 60 meters, and there are some vent holes. The surging water vapor makes the lake tumble with gray-blue blisters, as the name suggests, a boiling lake. ^[5]

Arctic snow chimney

Fumaroles in the Arctic let out steam from underground volcanoes. As soon as this heat leaves the ground, it will freeze instantly, and a large number of snow chimneys will form near the crater.
