Doomsday Fire: Millions of volcanoes stir beneath the oceans of the world

The volcanic islands and seamounts of the Pacific Ocean

In 1993, marine geophysicists aboard the research vessel Melville discovered 1,133 previously unsupported map underwater volcano off the coast of Easter Island. Some of them are increased by one and a half miles above the ocean floor, but most were still half a mile below the surface of the water. All this in a relatively small area of 55 thousand square miles, which corresponds to the size of the State of New York.

At the time of Geophysics increased the number of known submarine volcanoes by 10%. That was in 1993. Today, scientists estimate that there are more than three million underwater volcanoes!

In 2007, oceanographers Hillier and Watts spent exploring 201,055 submarine volcanoes. "As a result, they concluded that about 3,477,403 similar submarine volcanoes exist in the world," the article says.

Hillier and Watts based their conclusions on earlier studies Betizy (1982) — a recognized expert on Earth Observations — which found that at least 4 percent of underwater rock formations — active volcanoes.

According to studies Betizy, the Pacific plate alone contains an incredible amount of underwater volcanoes — from 22,000 to 55,000, of which at least 2,000 are active.

Of course, no one can know exactly how many volcanoes lurking below the surface of the ocean. However, the number of 3,477,403, which follows from the opening of two reputable oceanographers could mean that underwater volcanoes heated sea.

The increase in the number of open underwater volcanoes from 10 000 to more than 3 million in less than 20 years shows how little we know and how little we still know about this incredible force of nature. We know more about the moon.
