Listen to an UNDERWATER volcano erupt: Surprising sound of one of Earth's most violent events captured beneath the waves The majority of the world’s volcanoes are found deep underwater and now scientists have been able to record one of these eruptions as it happens to discover the sound it makes. The bubbling lava erupting from the volcanic vent Hades (above) produced a distinctive acoustic signature.

What is a subduction zone? These zones also exist where one oceanic crust is pushed under another oceanic crust, the same volcanism results, but as it takes place at sea the result is the formation of underwater volcanoes. 45 people found this useful.hese zones also exist where one oceanic crust is pushed under another oceanic crust, the same volcanism results, but as it takes place at sea the result is the formation of underwater volcanoes. 45 people found this useful.

Volcanoes: Force Of Nature And Wonder Fuelled by pockets of molten rock deep underneath the surface called magma, volcanoes allow lava and ash to escape from deep underground in powerful explosions. Magma that manages to break the surface is known as lava. Volcanoes are generally found where there is tectonic activity.

Why do volcanoes erupt? Below the magma chamber. Volcanoes that are located in subduction zones – where Earth’s moving plates collide, causing one plate to sink under the other – receive a steady injection of new molten rock into the magma chamber. Under the magma chamber, the heat of Earth’s core partially melts existing rocks into new magma.ruptions from this process are hard to predict. Above the magma chamber. Eruptions can also happen due to loss of pressure above the magma chamber. This can be caused by various things, such as a decrease in density of rocks above the chamber or the melting of ice atop a volcano.

Volcanic Eruptions A volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust. Volcanoes are described as active (in eruption), dormant (not erupting at the present time), or extinct (having ceased eruption; no longer active). Some volcanoes explode.

- Axial Seamount. Axial Seamount is the most active submarine volcano in the NE Pacific. It rises to a depth of 1400 m below sea level and is located approximately 300 miles off the coast of Oregon. Axial Seamount was the site of the world's first underwater volcano observatory called NeMO and has erupted most recently in 2015, 2011 and 1998.

- Usually, volcanic eruptions above water are the result of a magma-plume burning through a spot in the Earth's crust, or by the rising part of a magma convection cell.

Where can volcanoes occur? volcanoes can also occur at hot spots such as at the areas of the hawaiian islands and yellowstone in america this type of volcano forms when magma from the mantle rises to earth s surface through a certain spot in the middle of the plate i e the pacific plate for the hawaiian islands

All the planets and moons known to have volcanoes The islands of Hawaii were formed by underwater volcanoes that blasted out so much rock, it reached above the surface of the sea. Volcanoes have also changed the makeup of the atmosphere. By pumping greenhouse gases into the air, they have ensured that the planet doesn't freeze over – well, most of the time. But Earth isn't the only world with volcanoes. The more we explore the solar system, the more we find that they are common, and they can dwarf our homemade ones.

Volcano A volcano is a rupture on the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.hey are the most dangerous type of volcano. Examples include: Yellowstone Caldera in Yellowstone National Park and Valles Caldera in New Mexico (both western United States); Lake Taupo in New Zealand; Lake Toba in Sumatra, Indonesia; and Ngorongoro Crater in Tanzania.

Volcanoes Volcanoes are vents, fissures or openings in the Earth's crust from which hot ashes, gases and magma erupt.On land, volcanoes usually take the form of mountains or hills with one or more volcanic vents.But the vast majority of the world's volcanoes lie beneath the sea along the global oceanic ridges.olcanoes are vents, fissures or openings in the Earth's crust from which hot ashes, gases and magma erupt.

Underwater Volcanism Ned Rozell said. ...Though an underwater volcano now, the cone was at or near sea level when glaciers locked up much of the world’s water during the last ice age. The volcano has the potential to again grow into an island should it erupt with enough vigor; its summit is about 377 feet below the ocean’s surface.

Probably not, because most volcanoes, especially active ones, occur in only a few well-defined narrow bands across the face of Earth--something like wild animals confined to reservations.Actually, at most locations on Earth, you would only see a lot of sea water (but that's another story!).r even more exciting, would you see an erupting volcano?

- The Ring of Fire. Most volcanoes exist along the edges of tectonic plates, the gigantic rock slabs that float on liquid rock below, comprising the continents of the Earth’s surface. About 90% of all volcanoes exist within the Ring of Fire along the eastern and western edges of the Pacific Ocean.

Limnic eruption From Wikipedia, the free encyclopedia. Lake Nyos, silty after a limnic eruption. A limnic eruption, also referred to as a lake overturn, is a rare type of natural disaster in which dissolved carbon dioxide (CO 2) suddenly erupts from deep lake water, suffocating wildlife, livestock and humans.Such an eruption may also cause tsunamis in the lake as the rising CO 2 displaces water.Scientists believe earthquakes, volcanic activity, or explosions can trigger such an eruption.uch an eruption may also cause tsunamis in the lake as the rising CO 2 displaces water.

Underwater Volcano Forms New South Pacific Island Underwater Volcano Forms New South Pacific Island. Constant eruptions from an underwater volcano in the South Pacific Ocean starting in December created a new island over the last few months. Twenty five miles from Tonga, a nearby island nation, the freshly-made island won't last for too long, scientists say.

- Volcanic islands are formed by volcanic activity on the seabed, often near the boundaries of the tectonic plates that form Earth’s crust. Where two plates pull apart, lava erupts to form an undersea ridge. Layers of lava build up until a ridge breaks the sea’s surface to form an island. Sometimes a whole chain of volcanic islands, called an island arc, is formed in this way. Some island arcs contain thousands of islands.

Stanwich Volcano Many volcanoes occur near boundaries where two oceanic plates collide. Through subduction, the older, denser plate sinks beneath a deep-ocean trench into the mantle. Some of the rock above the subducting plate melts and forms magma. Because the magma is less dense than the surrounding rock, it rises toward the surface.

Poisonous gas emissions volcanoes emit gases that are Mudflows (Lahars) -Volcanoes can emit voluminous quantities of loose, unconsolidated ash and pyroclastics which become deposited on the landscape. Such loose deposits are subject to rapid removal if they are exposed to a source of water. -They have properties that vary between thick water and wet concrete.
