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

Volcanic eruptions in the Cascade Range of the Pacific Northwest over the last 2.6 million years are more numerous and closely connected to subsurface...

Photos may improve understanding of volcanic processes

The shape of volcanoes and their craters provide critical information on their formation and eruptive history. Techniques applied to photographs -- photogrammetry -- show...

New evidence of long-term volcanic, seismic risks in northern Europe

An ancient European volcanic region may pose both a greater long-term volcanic risk and seismic risk to northwestern Europe than scientists had realized, geophysicists...

How volcanoes explode in the deep sea

Explosive volcanic eruptions are possible deep down in the sea -- although the water masses exert enormous pressure there. An international team reports in...

Eruption of Alaska’s Okmok volcano linked to period of extreme cold...

An international team of scientists and historians has found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source:...

Study proves that magma chambers are huge masses of crystals with...

Wits University (University of the Witwatersrand, Johannesburg, South Africa) PhD student, Willem Kruger's study on the state of magma within plutonic magmatic systems in...

New hints of volcanism under the heart of northern Europe

Scientists have discovered new evidence for active volcanism next door to some of the most densely populated areas of Europe. The study 'crowd-sourced' GPS...

Discovery of ancient super-eruptions indicates the Yellowstone hotspot may be waning

Throughout Earth's long history, volcanic super-eruptions have been some of the most extreme events ever to affect our planet's rugged surface. Surprisingly, even though...

Philippine volcanic eruption could prompt El Nino warming next winter

Climatologists have found that if an ongoing Philippine volcanic eruption becomes more violent, the gases released are likely to produce an El Niño event...

Volcanic eruptions reduce global rainfall

Climate change is occurring all over the globe as 1°C increase in Earth's surface temperature has led to the sea level rise, abrupt melting...
