The Tamu block was discovered on September 5, 20 13. It is a dome-shaped volcano about 450 kilometers long and 650 kilometers wide. Its peak is 4460 meters above the seabed, but there is still a distance of about 2000 meters from the peak of the volcano to the sea surface.
Brief introduction of submarine volcano:
Submarine volcano is a volcano formed at the bottom of the ocean. Submarine volcanoes are widely distributed. The surface of lava erupted by submarine volcano is rapidly cooled by submarine seawater, like squeezing toothpaste, but the interior is still in a high heat state.
Most submarine volcanoes are located near tectonic plate movements called mid-ocean ridges. Although most undersea volcanoes are located in the deep sea, some are located in shallow water, and when they erupt, they will spray materials into the air. The hot gas eruption near the submarine volcano is rich in biological activities.
When underwater volcanoes erupt, spectacular explosions often occur when the water is shallow and the water pressure is not high. When this explosive underwater volcano erupts, it will produce a lot of gas, mainly water vapor, carbon dioxide and some volatile substances from the deep part of the earth, as well as a lot of pyroclastic materials and hot lava, which will condense into volcanic ash, volcanic bombs and pyroclastic rocks in the air.
