Those interested in the Active underwater volcanoes map category often ask the following questions:

🌊 How many active volcanoes are underwater?

If an estimate of 4,000 volcanoes per million square kilometers on the floor of the Pacific Ocean is extrapolated for all the oceans than there are more than a million submarine (underwater) volcanoes. Perhaps as many as 75,000 of these volcanoes rise over half a mile (1 kilometer) above the ocean floor.If an estimate of 4,000 volcanoes per million square kilometers on the floor of the Pacific Ocean is extrapolated for all the oceans than there are more than a million submarine (underwater) volcanoes
underwater) volcanoes
Many submarine volcanoes are seamounts, typically extinct volcanoes that rise abruptly from a seafloor of 1,000 - 4,000 meters depth. They are defined by oceanographers as independent features that rise to at least 1,000 meters above the seafloor.

🌊 How many active underwater volcanoes are there in the world?

The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct), of which some 75,000 rise more than 1 km above the seabed. Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes.The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct), of which some 75,000 rise more than 1 km above the seabed. Hydrothermal vents
Hydrothermal vents
A black smoker or deep sea vent is a type of hydrothermal vent found on the seabed, typically in the bathyal zone (with largest frequency in depths from 2500 m to 3000 m), but also in lesser depths as well as deeper in the abyssal zone. They appear as black, chimney-like structures that emit a cloud of black material.

What forms underwater volcanoes?

== Underwater volcanoes are formed at 'hot spots' in the Earth's mantle, as in the Hawaiian Island chain, or in deep sea trenches, where oceanic crust is subducting under oceanic crust, melting when it reaches the mantle, then erupting as a volcano.

Facts about underwater volcanoes?

Most underwater volcanoes are found at mid ocean ridges and erupt basaltic lava in a form called pillow basalts. The volcanoes at mid ocean ridges contribute to sea floor spreading. Volcanoes that develop underwater at hot spots or subduction zones are likely to build up into island

Are underwater volcanoes more dangerous than land volcanoes?

No, because land volcanoes can shoot debris around while an underwater volcano is being held back by water pressure. It is really quite simple.

Are volcanoes on land or volcanoes underwater more dangerous?

I'd say land volcanoes. They can destroy homes on land and underwater volcanoes can help make more land, like in Hawaii. And underwater volcanoes can also kill fish but they would most likely not live around them. no thay are no beause the sea ones do not kill any one because they are thousends of miles down

How are underwater volcanoes different from above ground volcanoes?

Underground volcanoes don't erupt as much as aboveground volcanoes and some of the volcanoes are extinct.

How do underwater volcanoes erupt?

  • Underwater volcanoes form much like volcanoes on dry land, by a process known as subduction. This occurs as a result of the tectonic plates which form the top layer of the earth's mantle, just below the earth's crust… The tectonic plates are on constant drift atop this layer of rock, occasionally two plates will pull just far enough apart for the molten rock to pass through and worm its way to the surface.

Can underwater volcanoes kill you?

Yes it can kill you, but not by the molten lava but by the waves that the eruption make or called "tsunami"

What do underwater volcanoes produce?

When magma reaches the level of the seafloor, it meets cold ocean water and quickly cools to form basaltic rock, often termed “pillow lava” due to its rounded shape. This pillow lava, along with slower-cooling magma beneath it, forms the vast majority of oceanic crust.

Do volcanoes only exist underwater?

Submarine volcanic eruptions are characteristic of the rift zones where crustal plates are being formed… Most seafloor spreading centers lie at depths exceeding 2,000 meters (1.2, miles) and, as a consequence, approximately three-quarters of all volcanic activity on Earth occurs as deep, underwater eruptions.
