Ritter Island gives new insights into the dynamics of volcanic landslides

Thu, 16/05/2019 - 16:46
The flanks of many island volcanoes slide very slowly towards the sea. Whether these landslides are forewarnings of a catastrophic collapse or, on the contrary, even reduce its risk, is not yet understood. Geophysicists now show that sporadic, slow landslides on the small volcanic island of Ritter Island in New Guinea preceded a catastrophic collapse.

From Earth's deep mantle, scientists find a new way volcanoes form

Wed, 15/05/2019 - 19:40
Far below Bermuda's pink sand beaches and turquoise tides, geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone -- a layer rich in water, crystals and melted rock -- can percolate to the surface to form volcanoes.

Iceland volcano eruption in 1783-84 did not spawn extreme heat wave

Wed, 15/05/2019 - 16:58
An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a new study. The study will help improve predictions of how the climate will respond to future high-latitude volcanic eruptions.

What does the future of Kilauea hold?

Fri, 26/04/2019 - 16:06
Ever since Hawaii's Kilauea stopped erupting in August 2018, ceasing activity for the first time in 35 years, scientists have been wondering about the volcano's future. Its similarities to the Hawaiian seamount Lo`ihi might provide some answers.

Snowmelt causes seismic swarm near California's Long Valley Caldera

Fri, 26/04/2019 - 12:54
A spring surge of meltwater, seeping through vertically tilted layers of rock, caused a seismic swarm near California's Long Valley Caldera in 2017, according to new research.

Mysterious eruption came from Campi Flegrei caldera

Thu, 25/04/2019 - 17:23
The caldera-forming eruption of Campi Flegrei (Italy) 40,000 years ago is the largest known eruption in Europe during the last 200,000 years, but little is known about other large eruptions at the volcano prior to a more recent caldera-forming event 15,000 years ago.

Scientists argue for more comprehensive studies of Cascade volcanoes

Fri, 22/03/2019 - 17:25
Scientists argue for more 'synthesis' research looking at the big picture of volcanology to complement myriad research efforts looking at single volcanoes.

Volcano cliffs can affect monitoring data

Thu, 21/03/2019 - 02:58
New research reveals that sharp variations of the surface of volcanoes can affect data collected by monitoring equipment.

2018's biggest volcanic eruption of sulfur dioxide

Thu, 28/02/2019 - 17:35
The Manaro Voui volcano on the island of Ambae in the nation of Vanuatu in the South Pacific Ocean made the 2018 record books. A NASA-NOAA satellite confirmed Manaro Voui had the largest eruption of sulfur dioxide that year.

'Amazing snapshots' plumb volcanic depths

Thu, 28/02/2019 - 15:36
Research shedding light on the internal 'plumbing' of volcanoes may help scientists better understand volcanic eruptions and unrest. The study analyzed crystals in Italy's famous Mount Etna to reveal how quickly magma moves to the surface.

Satellite images reveal interconnected plumbing system that caused Bali volcano to erupt

Thu, 14/02/2019 - 14:46
A team of scientists has used satellite technology provided by the European Space Agency to uncover why the Agung volcano in Bali erupted in November 2017 after 50 years of dormancy.

Extratropical volcanoes influence climate more than assumed

Mon, 28/01/2019 - 18:22
The eruption of Mount Pinatubo in 1991 had a significant impact on climate, decreasing global mean temperature by about 0.5°C. Like the famous eruptions of Krakatau (1883) and Tambora (1815), Pinatubo is located in the tropics, which has been considered an important factor underlying its strong climate forcing. New research shows that explosive extratropical eruptions can have a strong impact on the climate too.
