Are there any active volcanoes under the oceans? where are they?

Answer 1

Some people listed above have already answered this question...with regards if there are underwater volcanoes. There are also hydrothermal vents, which while not volcanoes, do put high temperature gasses into the ocean water, albiet at high pressures so the water doesn't boil.

Questions by the scientific community have surrounded man's causing global warming. I saw your question, and I have wondered if regular volcanoes, underwater volcanoes, hydrothermal vents, and areas that release methane are not larger causes of global warming...as global warming happened several times in the distant past without mankind affecting it. There was a recent story about permafrost in the Siberia region thawing, allowing trapped methane to escape...and methane was thought to be 100 times more powerful as a greenhouse gas than carbon dioxide.

Answer 3

Yes there are volcano active under the ocean. they can be found near any island arc chain. Also in the middle of our oceans are spreading ridges where material is added to the the oceanic crust. These are the drivers of plate techtonics.

Answer 4

The Mid-Atlantic rift is one long continous lava spewing fissure on the ocean floor.( Not certain if it would classify under the classic "volcano" term however)

Answer 5

Yes, there are some in the vicinity of Hawaii.
