Volcanoes on Venus recently erupted, new study finds

PASADENA, Calif. – Volcanic activity on Venus took place in the recent past, geologically speaking, and may still occur on the planet today. New research takes a deeper look at a recent eruption on the surface of Venus. The Idunn Mons volcano in the southwestern hemisphere of Venus rises 2.5 kilometers above the surrounding plains. […]

The giant volcanoes of Mars

A region of high altitude clouds in the Martian atmosphere appears on the horizon just to the left of Alba Mons. These clouds are on the lee side of the mountain relative to the prevailing winds in that region. They may be the result of air flowing over the mountainside, creating density waves that initiate […]

Supervolcano – super mystery | volcanoes

EIn an hour or two, the “Old Faithful” geyser in Yellowstone National Park, Wyoming shoots a column of boiling water up to 50m into the air. This incredible natural spectacle, along with multiple other geothermal features and the one to two thousand earthquakes that occur each year, are just some of the signs that this […]

Scientists recently realized 1,240 miles of volcanoes are connected | Smart News

“The Nut”, an ancient volcanic plug on Tasmania in Australia Jochen Schlenker/Masterfile/Corbis Sometimes it’s all about perspective. This is what scientists discovered when they realized that several small chains of volcanoes in Australia actually form a 2,000 km long “megachain”. Tia Ghose writes about what is now believed to be the world’s longest chain of […]

The largest continental chain of volcanoes ever discovered has just been discovered in Australia

Australia is known for its many dangers. Fires, floods, terrible temperatures, apocalyptic hellish landscapes… Volcanoes are one of the few natural disasters they have largely avoided. There are no active volcanoes on the Australian mainland, but step back a few million years and you’ll find a very different landscape. Researchers recently announced that they have […]

Hidden superchain of volcanoes discovered in Australia

Scientists have just discovered the world’s longest chain of volcanoes on a continent, hidden in plain sight. Australia’s recently discovered volcanic chain is not a total surprise, however: geologists have long known of the existence of small, distinct chains of volcanic activity on the island continent. However, new research reveals a hotspot once hidden beneath […]

World’s longest chain of continental volcanoes found hidden in Australia

The Cosgrove hotspot trail stretches the length of Australia from coast to coast. Drew Whitehouse, NCI National Facility VizLab The world’s longest continental volcanic chain has been discovered running the length of Australia, hidden deep beneath the earth’s crust. It stretches over 2,000 kilometers (1,243 miles), from the Whitsunday Islands in northern Queensland to near […]

Cosgrove Track: Scientists Discover World’s Longest Chain of Continental Volcanoes | Geoscience

An international team of researchers has discovered the world’s longest known continental volcanic hotspot Track — a length of 1,245 miles (2,000 km) Track in eastern Australia which shows a record of volcanic activity between 33 and 9 million years ago.

How Cracking Explains Underwater Volcanoes and the Hawaiian Bend

Geoscientists at the University of Sydney have helped prove that some of the ocean’s undersea volcanoes did not erupt from hotspots in Earth’s mantle, but instead formed from cracks or fractures in the oceanic crust. The discovery helps explain the dramatic bend in the famous seamount chain, the Hawaiian-Emperor Seamount Range, where the lower half […]

Volcanoes of Virginia linked to islands in the eastern Atlantic

The youngest volcanoes on the East Coast share an unusual geological connection with islands across the Atlantic Ocean, a new study has found. The new findings could explain the enigmatic origin of the 48-million-year-old volcanoes, which ripped through Virginia’s fractured crust long after other fiery eruptions had ceased along the East Coast. The surprisingly young […]

When did volcanoes last erupt on the east coast?

How Virginia’s Mole Hill became a mountain is an old story, but not as old as some geologists think. The reason for this has to do with volcanoes – and may help explain why the east coast of the United States, so long removed from geological upheavals compared to the west, still suffers from relatively […]

The ‘hot spot’ theory for the formation of Antarctic volcanoes is not well received

The mystery of how a chain of Antarctic undersea volcanoes formed may have finally been solved. The Marie Byrd Seamounts are a group of eight large volcanoes and numerous smaller cones covering the seafloor off West Antarctica. For geologists, volcanoes aligned like Russian dolls in the middle of a tectonic plate usually signal a mantle […]

New model of Earth’s interior reveals clues to hotspot’s volcanoes

[ad_1] Scientists at UC Berkeley have detected previously unknown channels of slow seismic waves in the Earth’s upper mantle, a discovery that helps explain the “hotspot volcanoes” that give rise to island chains such as Hawaii and Tahiti. This 3D view of the first 1,000 kilometers of the Earth’s mantle under the central Pacific shows […]
