A fumarole (or fumerole) [1] is a vent in the surface of the Earth or another rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids.

2019年4月29日 · A fumarole is an opening in the Earth’s crust that emits or vents gases and steam into the atmosphere. They can be found in active volcanoes, along tiny cracks in the Earth, and on the surface of lava flows. In most cases, the presence of fumaroles signifies active volcanic activity.

fumarole, vent in the Earth’s surface from which steam and volcanic gases are emitted. The major source of the water vapour emitted by fumaroles is groundwater heated by bodies of magma lying relatively close to the surface.

Fumaroles are vents or openings at the surface where volcanic gases and vapors are emitted. Fumaroles are common features on active volcanoes, and are an important sign that a volcano is active in that fumaroles indicate the presence of heat from volcanic sources. In between eruptions, fumaroles are one of the most dynamic features on volcanoes.

The meaning of FUMAROLE is a hole in a volcanic region from which hot gases and vapors issue.

Fumaroles are openings in the earth’s surface that emit steam and volcanic gases, such as sulfur dioxide and carbon dioxide. They can occur as holes, cracks, or fissures near active volcanoes or in areas where magma has risen into the earth’s crust without erupting.

2024年5月21日 · What is a Fumarole? A fumarole is a hole in the Earth's crust which vents gases. Fumaroles are usually found around areas of volcanic activity, although they can appear anywhere. If enough groundwater is present, the vent may turn into a hot spring, creating a supply of bubbling naturally hot water which is heated by the escaping gases.

2024年7月16日 · Fumaroles are vents from which volcanic gas escapes into the atmosphere. Fumaroles may occur along tiny cracks or long fissures, in chaotic clusters or fields, and on the surfaces of lava flows and thick deposits of pyroclastic flows.

A fumarole (Latin fumus, smoke) is an opening in the crust of the Earth, often in the neighborhood of dormant volcanoes, where steam and gases come out, for instance carbon dioxide, sulfur dioxide, hydrochloric acid, and hydrogen sulfide.

G eysers, fumaroles (also called solfataras), and hot springs are generally found in regions of young volcanic activity. Surface water percolates downward through the rocks below the Earth's surface to high-temperature regions surrounding a magma reservoir, either active or recently solidified but still hot.
