A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the ...

Last month, RPI researchers were the first to ever collect data during an underwater eruption on the Mid Ocean Ridge System. They happened to be on site to gather data from hydrothermal vents.

Scientists Stumbled Upon an Active Volcanic Eruption in a Mid-Ocean Ridge for the First Time Ever From a research submersible, scientists saw hardened lava, dead tube worms and orange flashes from ...

It stretches over 5,000 kilometers beneath the Indian Ocean, making it the Earth’s longest linear volcanic ridge. It also has an average width of around.) 200 km and a top height of 3.5 km. A ...

Spanning the north-south length of the Atlantic Ocean for around 10,000 miles, the Mid-Atlantic Ridge is the longest mountain range in the world yet it remains largely unexplored.

Researchers in a submersible could hardly believe their eyes, or their luck, when they saw a clearly active eruption along an undersea volcanic mountain chain.

“Over two-thirds of the Earth’s surface was formed by volcanic eruptions at these mid-ocean ridges,” said Maya Tolstoy, a marine geophysicist and Maggie Walker Dean of the UW College of the ...

An underwater volcano 300 miles off the coast of Oregon is displaying signs of a potential eruption, UW researchers found.

The Atlantic Ocean is widening every year because a mountain range under the water is a hotspot of geologic activity, according to a recent study.

An underwater volcano off the Oregon coast could erupt late this year, scientists say. The volcano, known as Axial Seamount, is more than 4,900 feet beneath the Pacific Ocean and 300 miles off the ...

"Most of the planet's volcanoes are located underwater, along the 65,000-km-long [40,000 miles] mid-ocean ridge system," Ed Llewellin, a professor of volcanology at Durham University in the United ...
