Volcanoes beneath ice in Antarctica could erupt and leave the planet uninhabitable, warn researchers

What are underwater volcanoes? Underwater volcanoes are also called submarine volcanoes. Experts estimate that there are around 1,500 active volcanoes on the surface of the plane, but there are at least 10,000 volcanoes in the Pacific Ocean alone. Water exerts at least 250 times more pressure on the surface of the earth than air and this higher pressure can lead to an underwater explosion. Because most underwater volcanoes erupt at a depth of about 2200 meters below sea level, where the pressure is more than 218 atmospheres, water can’t boil. The absence of a boiling sound makes it almost impossible to detect an underwater eruption, even with hydrophones or the underwater device used to detect and record ocean sounds from all directions.
