Banua Wuhu is located in the Sangihe Islands, 45 kilometers south of Awu, Indonesia. Both of the eruption were given a name, the first eruption was called Hades, while the second one was Prometheus. Unlike the land volcanoes, under the ocean volcanoes are mostly hard to detect and discover. The volcano forms a temporary island during eruptions, and subsequently erodes below sea level. As has been mentioned before, under the ocean volcanoes are generally located at mid-ocean ridges. During the expedition of NOAA (National Oceanic and Atmospheric Administration) in 2003, they discovered this volcano. The adjacent island of Mahengetang is part of the same volcanic edifice. In 1919 a 70 m long and 12 m high island formed, which disappeared by 1935. Iwo Jima morphology is different than the other island arc volcanoes, as it is unusually flat and featureless for a volcanic island. (see also: Sea Erosion). (See also: Ocean Plants), Because of its location, Iceland region is a region with frequent volcanic activities. volcanolive.com A magnitude 7.2 earthquake occurred 130 km NE of the volcano on 12th February 2009, at a depth of 20 km. The eruption finished on 28th June 1973 or 157 days, with several aftermaths, such as destroying almost 400 hundreds of homes, covering and burying the entire town of Vestmannaeyjar in ash, and sending lava flows toward the harbor.

Generally, seamount is not an island because it does not reach the ocean’s surface; it is actually a mountain rising from the ocean seafloor. The base of Nafanua is a toxic zone and covered by carcasses of dead fishes, squids, and crustaceans. However, in 2015, volcanologists believe that Iwo Jima may bring threat as it is regarded as the most dangerous volcano and there is 30% chance that it may erupt explosively in this century. Characteristic of Drought Season and Countries Experiencing It . The reason of the rising above the surface is the composition of the under the ocean’s ash, lava and debris that come up during the volcanic eruption. Sangihe Islands is known to be the region of many under the ocean volcanoes, such as Submarine 1922, and other active and non-active volcanoes. This active underwater volcanic cone is called Nafanua and it has been growing since 2001. During some of its eruption, Banua Wuhu has created islands that are temporary because they are eroded subsequently by waves. Submarine volcano (temporary island formation). (see also: Ocean Animals). What is the definition of a volcano? (see also: Ocean environment), The 1939 Kick ‘em Jenny’s eruption was the largest and most destructive. This caldera is studied to be formed around 37,000 – 51,000 years ago. The West Mata volcano is producing Boninite lavas, a type of lava that has only been seen on an extinct volcano that is older than a million years ago and it is believed to be among the hottest erupting on Earth. West Mata volcano also has a unique feature as the water from the volcano is very acidic and the only organisms that can survive the water’s acidity are shrimps. Wuhu hanya berjarak 300 meter dari pulau Mahangetan, di Wuhu terdapat gunung berapi di bawah laut yang bisa menggeluarkan gelembung-gelembung di kedalaman 8 meter. This active under the ocean volcano is also called Northwest Rota, it is located in the Pacific region and it is about 64 kilometers northwest of Rota Virgin Island. Besides Brothers Volcano, another under the ocean volcano located in the same region is Healy. Although natural disasters are something that are inevitable, as a mankind, we still need to dig further and explore more about these under the ocean volcanoes to find the pattern and more knowledge that may help us to prevent those disasters. Volcanoes may become a threat to mankind and its habitat. The eruption, which is located on the eastern side of Heimaey in the Westman island, nearly led to a permanent evacuation of the entire island of 5,000 population. Last know eruption happened in the year 2015. It is the youngest volcano of the Cobb-Eickelberg Seamount Chain.

The volcano forms a temporary island during eruptions, and subsequently erodes below sea level. Interesting Facts Recommended for you. A small submarine eruption occurred on 5th September 1968. This volcanic seamount was discovered by Rockne Johnson, a geophysicist, on 18th October 1975. It sent a cloud of ocean debris and steam as high as 275 meters into the air and generated a series of 2 meters high tsunamis to the northern part of Grenada and small tsunami to the west coast of nearby Barbados. Fortunately, in recent decades, volcanologists created a new system that listen to the acoustic wave produced by the vibrations under ocean.
