Volcanic eruptions examiner

Wed, 19/04/2017 - 22:04
Volcanologists spent two weeks collecting samples from Yasur, a continuously erupting volcano on Tanna, an island in the remote South Pacific archipelago of Vanuatu, to study its chemical composition and determine how the gasses it produces may be affecting people who live nearby.

Grand challenges to better prepare for volcanic eruptions

Wed, 19/04/2017 - 16:24
Despite broad understanding of volcanoes, our ability to predict the timing, duration, type, size, and consequences of volcanic eruptions is limited, says a new report. To improve eruption forecasting and warnings to save lives, the report identifies research priorities for better monitoring of volcanic eruptions and three grand challenges facing the volcano science community.

Drones collect measurements from a volcanic plume at Volcán de Fuego, Guatemala

Tue, 11/04/2017 - 15:45
A team of volcanologists and engineers have collected measurements from directly within volcanic clouds, together with visual and thermal images of inaccessible volcano peaks.

Mars volcano, Earth's dinosaurs went extinct about the same time

Tue, 21/03/2017 - 14:27
Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity, about 50 million years ago. The last volcanic activity there ceased about 50 million years ago -- around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct.

A perfect storm of fire and ice may have led to snowball Earth

Mon, 13/03/2017 - 21:08
What caused the largest glaciation event in Earth's history, known as 'snowball Earth'? Geologists and climate scientists have been searching for the answer for years but the root cause of the phenomenon remains elusive. Now, researchers have a new hypothesis about what caused the runaway glaciation that covered the Earth pole-to-pole in ice.

First global maps of volcanic emissions use NASA satellite data

Thu, 09/03/2017 - 21:06
A number of volcanoes around the world continuously exhale water vapor laced with heavy metals, carbon dioxide, hydrogen sulfide and sulfur dioxide, among many other gases. Of these, sulfur dioxide is the easiest to detect from space.

Can tree rings predict volcanic eruptions?

Thu, 09/03/2017 - 17:19
Scientists made a surprising discovery on their mission to find better indicators for impending volcanic eruptions: it looks like tree rings may be able to predict eruptions, report researchers.

Fossilized tree and ice cores help date huge volcanic eruption 1,000 years ago to within three months

Sun, 29/01/2017 - 17:16
An international team of researchers has managed to pinpoint, to within three months, a medieval volcanic eruption in east Asia the precise date of which has puzzled historians for decades. They have also shown that the so-called "Millennium eruption" of Changbaishan volcano, one of the largest in history, cannot have brought about the downfall of an important 10th century kingdom, as was previously thought.

The secret of the supervolcano

Thu, 26/01/2017 - 14:16
Researchers have now found an explanation for what triggered the largest volcanic eruption witnessed by humankind. The volcano’s secret was revealed by geochemical clues hidden inside volcanic quartz crystals.

New study will help find the best locations for thermal power stations in Iceland

Thu, 19/01/2017 - 14:38
A new research article gives indications of the best places in Iceland to build thermal power stations.

Deep mantle chemistry surprise: Carbon content not uniform

Fri, 13/01/2017 - 21:54
Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth's interior. Analysis of crystals containing completely enclosed mantle magma with its original carbon content preserved has doubled the world's known finds of mantle carbon.

Frequency of flight-disrupting volcanic eruptions estimated

Tue, 03/01/2017 - 16:17
Holidaymakers concerned about fresh volcanic eruptions causing flight-disrupting ash clouds across Northern Europe might be reassured by a study setting out the first reliable estimates of their frequency.
