. Hydrothermal vents are often associated with undersea volcanoes. Underwater volcanic eruptions and magma flows on the sea floor have been seen for the first time ever thanks to video captured by NOAA. This is because the vents are created and sustained by the heat of volcanic activity at tectonic plate boundaries found throughout the globe.

James Williams talks. Three thousand feet 900 meters beneath the sea surface in the middle of the Pacific Ocean lies one of the worlds largest volcanoes called Havre. At these locations seawater seeps through cracks in the seafloor and is heated by molten rock.

There are at least 1500 active volcanoes on the surface of the earth but it is estimated that there may be more than 10000 volcanoes in the Pacific Ocean alone. Even though most submarine volcanoes do not produce the spectacular eruption events of some of their land counterparts undersea volcanic activity is a constant process that shapes the features of the ocean. The magnitude of its most recent eruption rivals some of the most memorable eruptions in recent historyfor up to 90 days in 2012 lava poured out from a total of 14 vents around the semicircular volcanic opening.
