Pillow lava formed by a submarine volcano NOAA exploration video showing remnants of underwater tar volcanoes. Circular plumes from a submarine eruption near Tonga. Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt.
The eruption produced a high eruption column, reaching elevations of 57 kilometres (35 mi) and thus reaching into the mesosphere; this is the highest known eruption column in history. [73] The column developed multiple "umbrella"-like clouds, a higher one in the stratosphere and a lower at about 17 km (11 mi) elevation, [ 74 ] and generated a ...
The volcano has remained relatively active since the 1996 swarm and is monitored by the United States Geological Survey (USGS). The Hawaii Undersea Geological Observatory (HUGO) provided real-time data on Kamaʻehuakanaloa between 1997 and 1998. Kamaʻehuakanaloa's last known eruption was in 1996, before the earthquake swarm of that summer.
This image captured May 14, 2022, by NASA's Landsat 9, shows a plume of discolored water being emitted from the 'Sharkcano,' an underwater volcano that lies about 15 miles south of Vangunu Island.

The unnamed undersea volcano, located about 1 kilometer (half a mile) off the southern coast of Iwo Jima, which Japan calls Ioto, started its latest series of eruptions on Oct. 21.
Submarine eruptions are volcano eruptions which take place beneath the surface of water. These occur at constructive margins, subduction zones and within tectonic plates due to hotspots. This eruption style is far more prevalent than subaerial activity. For example, it is believed that 70 to 80% of the Earth's magma output takes place at mid ...
A list of active and extinct submarine volcanoes and seamounts located under the world's oceans. There are estimated to be 40,000 to 55,000 seamounts in the global oceans. [1] Almost all are not well-mapped and many may not have been identified at all. Most are unnamed and unexplored.
