What lies beneath: Volcanic secrets revealed

Lava samples have revealed a new truth about the geological make-up of the Earth's crust and could have implications for volcanic eruption early warning...

A journey into an Alaskan volcano

I'm writing this note from the Steadfast; an old 108 ft long crabber boat equipped with a helipad, crane, five state rooms, kitchen, living...

Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s...

A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs...

Volcanism drove rapid ocean deoxygenation during the time of the dinosaurs

Ocean deoxygenation during the Mesozoic Era was much more rapid than previous thought, with CO2 induced environmental warming creating ocean 'dead zones' over timescales...

Volcanoes acted as a safety valve for Earth’s long-term climate

Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon...

Giant friction experiment at Kilauea volcano

On April 30, 2018, on the eastern flank of Hawaii's Kīlauea volcano, lava suddenly drained from a crater that had been spewing lava for...

Sea levels influence eruptions on volcanic island

The rise and fall of sea levels influence the likelihood of volcanic eruptions on the Greek island of Santorini, new research led by Oxford...

Volcanic tremor and deformation at Kīlauea

Kīlauea in Hawaii is the best-monitored volcano in the world. The 2018 eruption was the largest in some 200 years, providing researchers with a...

New model for shield volcano eruption

There are some large shield volcanoes in the world's oceans where the lava is usually not ejected from the crater in violent explosions, but...

Supervolcano fed from Earth’s mantle caused crustal plates to rotate

The plates of the Earth's crust perform complicated movements that can be attributed to quite simple mechanisms. That is the short version of the...

Analysing volcanoes to predict their awakening

What causes an eruption? Why do some volcanoes erupt regularly, while others remain dormant for thousands of years? A team of geologists and geophysicists,...

New knowledge of Earth’s mantle helps to explain Indonesia’s explosive volcanoes

Indonesia's volcanoes are among the world's most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala...

Energy unleashed by submarine volcanoes could power a continent

Volcanic eruptions deep in our oceans are capable of extremely powerful releases of energy, at a rate high enough to power the whole of...

Hidden magma pools pose eruption risks that we can’t yet detect

Volcanologists' ability to estimate eruption risks is largely reliant on knowing where pools of magma are stored, deep in the Earth's crust. But what...

When volcanoes go metal

What would a volcano -- and its lava flows -- look like on a planetary body made primarily of metal? A pilot study from...

Volcanic eruptions had large and persistent impacts on global hydroclimate over...

Large tropical volcanos have caused some of the world's most destructive natural disasters in history, with eruptions spewing out massive quantities of harmful gases...

Unusual earthquakes highlight central Utah volcanoes

If you drive south through central Utah on Interstate 15 and look west somewhere around Fillmore, you'll see smooth hills and fields of black...

How do you know where volcanic ash will end up?

When the Eyjafjallajökull volcano in Iceland erupted in April 2010, air traffic was interrupted for six days and then disrupted until May. Until then,...

Antarctic Lava Yields Clues to Earth’s Past Magnetic Field

The movement of molten metals in Earth's outer core generates a vast magnetic field that protects the planet from potentially harmful space weather. Throughout...

Scientists identify flank instability at a volcano with history of collapse

Landslides caused by the collapse of unstable volcanoes are one of the major dangers of volcanic eruptions. A method to detect long-term movements of...
