15 Facts About Ocean Volcanoes

by Ayu Mesdya

15 facts about ocean volcanoes, there is always an interesting story behind the ocean volcanic eruptions. But do you know the origin of the ocean volcano? What about facts about the ocean volcano? Why are the ocean volcanoes labeled as the most destroyer in the world? Is it true that ocean volcanoes are the greatest threats on earth? Find the complete answer under 15 facts about ocean volcanoes. So, here we go.

1. The origin of ocean volcanoes

The ocean volcano comes from the process of the formation of the volcanic and it appeared at a depth of 1000 to 4000 meters from under the sea.

The fact is that around the world there are as many as 30.000 ocean volcanoes scattered. One is the Mauna Kea, this ocean volcano that located in the Hawaiian Islands, United States. Maua Kea is a volcano that basically starts from the bottom of this sea has a height of about 6000 meters below the Pacific Ocean and once erupted hundreds of years ago.

Next, to this volcano, there is another ancient volcano named Maua Loa, it is a long volcano with this form of the shield has volcanic volumes up to tens of thousands of kilometers. See also Volcano under The Ocean

2. The activity history of ocean volcanoes

Banua Wuhu is located in the waters of the island of Sangihe, North Sulawesi in Indonesia. It is one of the highest ocean volcanoes in the world.

The activity history recorded this volcano erupted early in 1835 and last record it erupted in 1968. This volcano until now is still active.

3. Ocean volcanoes eruption

The eruption of ocean volcano is very small detected. However, in terms, the process how are volcanoes eruption is still the same as the volcanoes on the land.

The magma that is buried as far as 10 kilometers under the sea. That the high pressure of the gas (earth) it will compel the magma chamber to comes out. So, the higher the gas pressure it will be higher the eruption of the ocean volcanoes. See also   Types of Rocks on Ocean Floor

4. Effects of the eruptions of ocean volcanoes

While the ocean volcano erupts, it will be a lot of negative effects will occur. First, when the eruption comes, it will definitely lot of bodies down over this disaster. It is not also human, but the biodiversity in the ocean could also be dead in no time.

Then, there is an aftereffect of an ocean volcanic eruption too. The scariest thing is the occurrence of Tsunami (the big wave). It could sweep the entire of Mainland. Otherwise, the eruption of ocean volcano can accelerate global warming.

The changes in this weather and climate, it would be felt by all of worldwide. It will be a little hotter than usual.

5. The high temperature of ocean volcanoes

The lava that comes out of the ocean volcano, the temperature of the lava is just as temperature volcanoes on the land.

The heats temperature of lava on ocean volcano reached more than 10 thousand degrees Celsius. The temperature is as high as the volcanoes on the land. But this high temperature of lava does not make the ocean evaporates.

The researchers found that any heat coming out from the lava of the ocean volcano is capable muted by the ocean. The other facts, that the researchers explain that under of the ocean, the heat of lava it can melting out to spout ashes. See also Importance of Ocean Temperature

 6. Lots of volcanic ash

While the ocean volcanoes eruption, it would launch the volcanic ash. It contains silica, iron, aluminum, and various types of gas. The volcanic ash particles are small and sharp. It is very easy to spread and be carried away by ocean currents up to tens of kilometers.

However, when the volcanic ash is spread by wind and then inhaled by humans so it can cause the respiratory disorders. This disorders can be serious if inhaled continuously. But there is one of the positive effects of this ash, in agriculture, the volcanic ash positively is very useful to fertilize the plants.

7. Lots of smoke

In addition to lots of ash emitted by the ocean volcano, at the same time, it is also released gas that very much. The ocean volcanic gas that occurs in the eruption is from the solid rock that heated by high-pressure temperature.

Then, this vulcanic gas mix with the air and produces gas like; hydrogen dioxide, carbon dioxide, carbon monoxide, nitrogen oxide, hydrogen and even sulfur dioxide. These are gases really could kill animals and the biodiversity that lives around the ocean volcano. See also Facts of Dead Sea

8. The ecosystems of ocean volcanoes

It is so much different and unique the ecosystems of ocean volcanoes than ecosystem volcanoes on the land. There are many hydrothermal vents or it is usually called black smokers.

It is commonly found around the ocean volcanoes in around the world. The black smokers contain hydrogen sulfide, water, and other minerals.

However, from this sulfur the ecosystems created. You will find the creatures like bacteria, tube worms, crabs, shrimps, and more unique organisms. Why can these creatures live in the danger zone? It is simple there are many sources of food around post ocean volcano eruption.

9. The sound of the eruption of ocean volcano

When a volcano (on land) erupts its voice sounds explosive and booming. Accompanied by the abundance of volcanic ash and the gases coming out of the volcano.

This also happens similarly to ocean volcano (under the ocean). The difference when the volcano erupts in the ocean explosion is muffled by the ocean. So that, the explosion becomes quiet and hissing.

Lava that comes out from the body of the volcano under the ocean is also moving slowly with gases coming out of black smokers. Some rocks are out drifting by ocean currents and it rises to the surface of the sea. See also Sea Sponges Facts

10. The ring of fire

Ring of fire is the name for the area along the Pacific Ocean where the area is seeing earthquakes and volcanic eruptions. This area has a hollow that looks like a horseshoe that surrounds the Pacific Ocean along the 40,000 kilometers. In a region of tens of thousands of kilometers, this is home to both active and inactive volcanoes by 75 percent.

11. New activity

The child of Mount Krakatau that located in the Sunda Strait, Indonesia. Now, the researchers set this ocean volcano in the status of alert II. In a news site online said that the increase of the volcanic activity is can happen anytime and it is very likely to occur of the eruption.

Besides, the Kilauea volcano in Hawaii Island it now erupts. The last update last Wednesday in a site news. The hot lava that is coming out will threaten the flood Pohoiki, Isaac Hale Park. See also Interesting Facts of Ocean Acidification

12. Ocean volcanoes active today

Kikai, Japan this ocean volcano recorded history ever erupted in 7,300 years ago this is allegedly active again. Some researchers found lava dome that has 32 million cubic kilometers and up to now, the dome continues to grow to have a width of tens of kilometers.

The most worrying thing is this volcano can erupt at any time without any warning. When this happens, the explosion can kill up to hundreds of millions of people. In addition, the eruption of this volcano could also cause a very severe global impact on volcanic winter.

13. The biggest disaster

The eruption of the volcano is one of the biggest disasters that threaten human and other livings. In 2012 some scientist gets information that the near of water of New Zealand. They found a stone that comes from the ocean volcanic eruption.

This stone is believed to originate from the Havre mountain, White Island, New Zealand. Some researchers found some facts that are the slow-moving lava that flows, the magma domes are pilling up and the signs of the eruption which is not explosive. See also Facts about Starfish

14. The Greatest ocean volcano

It has been found, Tamu Massif, the greatest ocean volcano on the Earth. This ocean volcano is located on the bottom of the Pacific Ocean to the Northwest. This ocean volcano is closest to a country called Japan. The researchers say that the greatest ocean volcano is very proportional to the size of New Mexico or the islands of the United Kingdom.

This volcano reached 643 kilometers and it is covering hundreds of kilometers. That is why this volcano called Mega volcano. Tamu Massif is established as the super greatest ocean volcano on the earth exceeds the Mauna Loa in Hawaii.

15. The death ocean volcanoes

Krakatau Mountain located in the Sunda Strait of Indonesia is referred to as the most deadly ocean volcanoes. It was mentioned that in 1883 it burst to bear that occurred, the explosive power of 30,000 times the Nagasaki and Hiroshima atomic bombs bearing World War II.  However, when Krakatau erupts, in a moment the world becomes dark.

This is the zone of volcanic ash that enters the atmosphere. Volcanic ash even looks up into the sky of Norway to New York. In the history of this explosion also occurred, it causing a powerful Tsunami to kill thousands of people.

This disaster is called the greatest disaster that ever happened at that time. However, from explosions that destroy some parts of the body Krakatau and it leaves some islands such as; Rakata Island, Long Island, and Sertung Island. See also Facts of Sharks 

The 15 facts about ocean volcanoes are very interesting, both volcanoes (on land) and ocean volcanoes have their own uniqueness. Hopefully with 15 facts about ocean volcanoes can be useful for you and the people who want learn more about the ocean volcanoes.
