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...

Unravelling the when, where and how of volcanic eruptions

There are about 1,500 potentially active volcanoes worldwide and about 50 eruptions occur each year. But it's still difficult to predict when and how...

Lava lake forms as Hawaii volcano erupts after 2-year break

Lava was rising more than 3 feet (1 meter) per hour in the deep crater of a Hawaii volcano that began erupting over the...

Volcanic eruptions directly triggered ocean acidification during Early Cretaceous

Around 120 million years ago, the earth experienced an extreme environmental disruption that choked oxygen from its oceans. Known as oceanic anoxic event (OAE) 1a,...

Scientists develop new approach to understanding massive volcanic eruptions

A geosciences team led by the University of South Florida (USF) has developed a new way to reconstruct the sizes of volcanic eruptions that...

Crystals may help reveal hidden Kilauea Volcano behavior

Scientists striving to understand how and when volcanoes might erupt face a challenge: many of the processes take place deep underground in lava tubes...

Piecing together the Alaska coastline’s fractured volcanic activity

Among seismologists, the geology of Alaska's earthquake- and volcano-rich coast from the Aleutian Islands to the southeast is fascinating, but not well understood. Now,...

Geoscientists discover Ancestral Puebloans survived from ice melt in New Mexico...

For more than 10,000 years, the people who lived on the arid landscape of modern-day western New Mexico were renowned for their complex societies,...

Volcanic eruptions have more effect in summer

Detailed modeling of the effect of volcanic eruptions on the El Niño Southern Oscillation (ENSO) has shown that the climate response to these events...

Magma ‘conveyor belt’ fuelled world’s longest erupting supervolcanoes

International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active...

Volcanic eruptions may explain Denmark’s giant mystery crystals

Researchers have long been stumped for an explanation of how tens of millions of years-old giant crystals known as glendonites came to be on...

Scientists shine light on tiny crystals behind unexpected violent eruptions

In a new study of volcanic processes, Bristol scientists have demonstrated the role nanolites play in the creation of violent eruptions at otherwise 'calm'...

Volcanic ash may have a bigger impact on the climate than...

When volcanoes erupt, these geologic monsters produce tremendous clouds of ash and dust -- plumes that can blacken the sky, shut down air traffic...

Rebirth of a volcano : Evolution of Bezymianny volcano, Kamchatka after...

Volcanoes are born and die -- and then grow again on their own remains. The decay of a volcano in particular is often accompanied...

Probing the origin of the mantle’s chemically distinct ‘scars’

The composition of Earth's mantle was more shaped by interactions with the oceanic crust than previously thought, according to work from Carnegie's Jonathan Tucker...

Pumice arrives delivering ‘vitamin boost’ to the reef

The giant pumice raft created by an underwater volcanic eruption last August in Tonga has begun arriving on the Australian eastern seaboard, delivering millions...

Study rewrites the recent history of productive Cascade Arc volcanoes
