Can Hobbits Swim? ‘Mordor Under The Sea’ Found Off Australia

2018-01-25T11:04:10+00:00 January 25, 2018|

(Credit: P. Reynolds, S. Holford, N. Schofield, and A. Ross) Today in news best suited for sneaky little Hobbitses and Shire-folk, scientists unveiled a map of a faraway volcanic realm that has a distinct look of Mordor about it. Unfortunately for any ring bearers, the molten landscape has probably been hidden underwater for millions [...]

Aquatic Robot Braves Volcanoes and Typhoons to Detect Tsunamis

2017-01-31T09:49:44+00:00 January 31, 2017|

The newest and most dangerous island in the world is about to get a robotic sentinel. Since bursting to life 1,000 kilometers south of Tokyo in 2013, a massive marine volcano called Nishinoshima has erupted dozens of times, spewing red-hot lava that engulfed a neighboring island. As the volcano has grown, so has the risk it represents to 2,500 people living on the nearby Japanese archipelago of Ogasawara. Should Nishinoshima’s rocky slopes collapse during an eruption, they could trigger a deadly tsunami that would reach the Ogasawara islands within 20 minutes.

Member Highlight: Underwater Volcano’s Eruption Captured In Exquisite Detail By Seafloor Observatory

2018-01-02T13:58:17+00:00 January 24, 2017|

The cracking, bulging and shaking from the eruption of a mile-high volcano where two tectonic plates separate has been captured in more detail than ever before. A University of Washington study published this week shows how the volcano behaved during its spring 2015 eruption, revealing new clues about the behavior of volcanoes where two ocean plates are moving apart.

A Massive Underwater Volcano Eruption Is Captured In Real Time

2016-12-19T12:24:56+00:00 December 19, 2016|

The sea floor split open on April 24, 2015, but scientists had seen it coming for months. Drawing on data from more than a dozen instruments arrayed around the underwater volcano known as Axial Seamount, they documented telltale tremors that shook its slopes. They watched the caldera at the top of the volcano swell like a balloon filling with air, building up pressure until it finally burst. They couldn't see much of the eruption that happened next — the water was too cloudy with debris — but they know that it involved plumes of super hot water and bubbles of gas and steam that popped with the explosive force of a mortar round. By the time the eruption ended a month later, nearly 88 billion gallons of molten rock had flooded ocean bottom.

Underwater Network Gives Scientists A Rare Glimpse Into Deep-Sea Volcanoes

2016-12-19T09:08:07+00:00 December 19, 2016|

Most volcanic eruptions on Earth happen in a hidden, dark place: deep underwater. Scientists rarely detect these outbursts on the sea floor, but last year, they caught a seamount eruption in the act. Now, researchers have characterized it in unprecedented detail—showing how a rash of earthquakes preceded the eruption and how bulging of the volcano’s surface was used to successfully forecast the eruption. Scientists say the results will help them understand how other volcanoes around the world behave.

Magma Boils Beneath Antarctic Ice

2016-06-28T19:37:07+00:00 November 18, 2013|

Marie Byrd Land is a desolate region of Antarctica buried deep beneath the West Antarctic Ice Sheet. But while the surface of Earth may be frozen, underneath is a different story.

Lost Land Beneath the Waves

2016-06-28T19:39:11+00:00 February 25, 2013|

Geological detectives are piecing together an intriguing seafloor puzzle. The Indian Ocean and some of its islands, scientists say, may lie on top of the remains of an ancient continent pulled apart by plate tectonics between 50 million and 100 million years ago.

New Study Finds Major Differences in Motions of Volcanic “Hotspots”

2016-06-29T09:24:10+00:00 November 26, 2012|

The movement of tectonic plates over a volcanic hotspot typically results in a narrow chain of seamounts, such as the Hawaiian-Emperor Seamount Trail. This hotspot trail is fed by a deep-mantle plume, which scientists believe drifted 15 degrees southward over millions of years because of a Pacific Ocean-wide “mantle wind.”

Surprise Underwater Volcanic Eruption Discovered

2016-06-29T10:22:06+00:00 August 16, 2011|

An undersea volcano has erupted off the coast of Oregon, spewing forth a layer of lava more than 12 feet (4 meters) thick in some places, and opening up deep vents that belch forth a cloudy stew of hot water and microbes from deep inside the Earth.

Giant Underwater Volcanoes Discovered

2016-06-29T10:22:14+00:00 July 15, 2011|

In the first ever-survey of its kind, a chain of massive volcanoes that rise up to 1.86 miles were discovered lurking beneath Antarctic waters near the South Sandwich Islands in the remote Atlantic Ocean.

Submarine Volcanoes Hint at Earth’s Formation

2016-06-29T10:24:19+00:00 February 16, 2011|

Ancient Undersea Volcanoes Yield Clues to Earth Dynamics

2016-06-29T10:24:20+00:00 February 15, 2011|

Over 800 meters (nearly half a mile) of rock pulled from below the seafloor near the coast of New Zealand may yield new clues to understanding how some hotspot volcanoes are created and whether and how the sources of these volcanoes have moved over time deep within the Earth.

Scientists Find Ancient Asphalt Domes Off California Coast

2016-06-29T10:46:09+00:00 May 4, 2010|

They paved paradise and, it turns out, actually did put up a parking lot. A big one. Some 700 feet deep in the waters off California's jewel of a coastal resort, Santa Barbara, sits a group of football-field-sized asphalt domes unlike any other underwater features known to exist.

Deciphering the Mysteries of an Ancient Seafloor Goliath

2016-06-29T10:46:21+00:00 April 9, 2010|

“Supervolcanoes” have been blamed for multiple mass extinctions in Earth’s history, but the cause of these massive eruptions remains poorly understood. To explore the origins of these seafloor giants, scientists drilled into a large, 145 million-year-old volcanic mountain chain lying underwater off the coast of Japan.
