Underwater volcanoes also known as
Submarine volcanoes are found under ocean and can generally eject into
air after eruption. Underwater volcanoes are formed when molten rocks
erupts underwater fissures of planet earth. They are usually found near
the areas of tectonic plate movement. Many
underwater volcanoes have caused chaos by eruption or earthquake by
destroying various places nearby leaving many homeless.
1. Coast of Tonga
Hunga Tonga is located about 30km from
Falcon Island. Volcano lies about 65 miles above a very seismic zone.
Many underwater volcano have been erupted here first ever volcano
erupted here was in 1912 This volcano was erupted on march 18, 2009
caused due to the melting of two tectonic plates using excessive amount
of heat and pressure resulting in the big eruption. Volcano extends from
New Zealand to north-east to Fiji.
2. Loihi Volcano, Hawaii
Loihi is an undersea mountain located in
south-west of High Island in Hawaii rising approximately 3000meters
above the Pacific Ocean. It is also knows as youngest volcano. Loihi was
first discovered in 1970 but scientists claimed it to be a normal
seamount, but Loihi proved to be an active volcano later in 1996 where
first eruption took place. And since then small earthquakes has been
hitting all over due to the volcanic eruption. Scientists strongly
believe that it can break the surface anytime from 10 to 10,000 years.
3. Eldfell Volcano, Iceland
Eldfell is located over 600 feet high on
Heimaey Island, Iceland. Many volcanic eruptions has been occurred here
because it is located over mid Atlantic ridge, where north American
and Eurasian are moving apart over Iceland hotspot causing many volcanic
eruptions. First ever volcanic eruption took place in January 1973 in
the Icelandic town of Vestmannaeyjer. Eruption took place at a sudden
without alarming people of this town. It destroyed entire town and
Heimaey Island was immediately evacuated.
4. Yasur Volcano, Vanuatu
Source: Unknown
Yasur volcano is located in Tannu
Island, Vanuatu The first ever eruption discovered here was in 1774.
Yasur is Vanuatu’s most active volcanoes. Its has been erupting
frequently for the past 800 years. Eruption starts with a strong
shockwave distributing huge clouds of smokes everywhere. Then there is a
huge explosion of molten chock of rocks. During the daytime they are
dark and gray but during the night they are surrounded by orange color.
5. Sumatra, Indonesia
Sumatra is an Island
located in Western Indonesia. It is the largest island in the Indonesia
and worlds sixth largest Island in the world. Sumatra is formed by long
chain of mountains and it is 4,600 meters tall and covers base of 50kms
in diameter below the surface of the ocean. There are about 90 volcanoes
in this range and 15 of them are active. The underwater earthquake
appeared here was the main responsible of tsunami that affected and
rocked the Asia in 2004.
