Submarine volcanoes Submarine volcanoes Bogoslof Island is the summit of a largely submarine stratovolcano located in the Bering Sea 50 km (31 mi) behind the main Aleutian volcanic arc. The peak elevation of the island is 150 m (492 feet). It is located at . It last erupted in 1992. ...more on Wikipedia about "Bogoslof Island"
Lo ihi is a seamount and undersea volcano in the Hawaiian archipelago, located at 18.92°N, 155.27°W—roughly 30 km (19 mi) south of the southeast coast of the Island of Hawai i. It is one of three very active volcanoes (the other two are Mauna Loa and Kīlauea) thought to presently sit over the Hawaiian hotspot. The greatest distance between the summits of these volcanoes is about 80 km (50 mi), approximately the diameter of the hot spot. However, Lo ihi has yet to build to the surface of the ocean, although it is now over 3000 m (10,000 ft) high (taller than Mount St. Helens). The top of Lo ihi lies 969 m (3,178 ft) below the surface. If the rate of upward building is about the same as nearby Kīlauea, Lo ihi should appear at the surface in several tens of thousands of years. ...more on Wikipedia about "Loihi Seamount"

Submarine volcanoes and volcanic vents are common features on certain zones of the ocean floor. Some are active at the present time and, in shallow water, disclose their presence by blasting steam and rock-debris high above the surface of the sea. Many others lie at such great depths that the tremendous weight of the water above them results in high, confining pressure and prevents the formation and explosive release of steam and gases. Even very large, deepwater eruptions may not disturb the ocean surface. ...more on Wikipedia about "Submarine volcano"
