Chance played a major role in keeping Earth fit for life
A study by the University of Southampton gives a new perspective on why our planet has managed to stay habitable for billions of years - concluding it is almost certainly due, at least in part, to luck. The research suggests this may shorten the odds of finding life on so-called 'twin-Earths' in the Universe. (2020-12-14)

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 -- erupting for 30 million years -- fuelled by a constantly moving 'conveyor belt' of magma. (2020-11-03)

New study takes the pulse of a sleeping supervolcano
Under the volcanoes in the Andes where Chile, Argentina and Bolivia meet, there is a gigantic reservoir of molten magma. For several million years, it has been there without fully solidifying or causing a supervolcanic eruption. Geologists have long wondered how this is possible. Researchers from Uppsala University, among others, have now discovered that the secret may be hidden tributaries of hot magma from inside the Earth. (2020-04-23)

The final stage before a big bang?

Zircon as Earth's timekeeper: Are we reading the clock right?
Zircon crystals in igneous rocks must be carefully examined and not relied upon solely to predict future volcanic eruptions and other tectonic events, QUT researchers have shown. (2017-10-22)

Magma chambers have a sponge-like structure
ETH researchers show that magma chambers under supervolcanoes are more like soggy sponges than reservoirs of molten rock. Before a volcano of this kind erupts, such mush must slowly be reactivated by heat input following deep magma recharge ultimately derived from the Earth's mantle. (2017-10-05)

Supervolcanoes: A key to America's electric future?
Stanford researchers show that lake sediments preserved within ancient supervolcanoes can host large lithium-rich clay deposits. A domestic source of lithium would help meet the rising demand for this valuable metal, which is critical for modern technology. (2017-08-16)

Deep magma reservoirs are key to volcanic 'super-eruptions', new research suggests

New study documents aftermath of a supereruption, and expands size of Toba magma system
The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades -- and a new study has found that these sites also may experience ongoing, albeit smaller eruptions for tens of thousands of years after. (2017-05-16)

The secret of the supervolcano
Researchers have now found an explanation for what triggered the largest volcanic eruption witnessed by mankind. The volcano's secret was revealed by geochemical clues hidden inside volcanic quartz crystals. (2017-01-26)

Scientists gain supervolcano insights from Wyoming granite
A new National Science Foundation-funded study by University of Wyoming researchers suggests that scientists can go back into the past to study the solidified magma chambers where erosion has removed the overlying rock, exposing granite underpinnings. (2016-06-02)

How rivers of hot ash and gas move when a supervolcano erupts
A new study in Nature Communications sheds light on what happens when a supervolcano erupts, providing insight on how rivers of hot ash and gas called pyroclastic flows manage to travel huge distances of over 100 miles during supereruptions. The research combines recent laboratory experiments with field data from the 1980s -- some of it captured in colorful Kodachrome slides -- to provide a somewhat counterintuitive finding. (2016-03-07)

Study challenges widely accepted theory of Yellowstone formation
Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held theories about the Yellowstone supervolcano's origins, adding to the mystery of Yellowstone's formation. (2016-02-10)

Supervolcanoes likely triggered externally, study finds
Supervolcanoes, massive eruptions with potential global consequences, appear not to follow the conventional volcano mechanics of internal pressure building until the volcano blows. Instead, a new study finds, such massive magma chambers might erupt when the roof above them cracks or collapses. (2015-11-04)

Magma pancakes beneath Lake Toba
Where do the tremendous amounts of material that are ejected to from huge volcanic calderas during super-eruptions actually originate? (2014-10-30)

Supervolcanoes discovered in Utah
Evidence of an eruption 5,000 times larger than Mount St. Helens was found in the Utah desert, with traces of ash identified as far away as Nebraska. (2013-12-09)

EARTH: Setting off a supervolcano
Supervolcanoes are one of nature's most destructive forces. In a matter of hours, an eruption from a supervolcano can force thousands of cubic meters of molten rock above ground, and scar landscapes with massive calderas and craters. These catastrophic eruptions have a global impact, and yet scientists still do not fully understand them. Today, a team of scientists studying Bolivia's Uturuncu volcano is trying to shed some light on how supervolcanoes can become so powerful. (2012-01-19)

Supervolcanoes: Not a threat for 2012
The geological record holds clues that throughout Earth's 4.5-billion-year lifetime massive supervolcanoes, far larger than Mount St. Helens or Mount Pinatubo, have erupted. However, despite the claims of those who fear 2012, there's no evidence that such a supereruption is imminent. (2011-11-15)

Mega eruption of Yellowstone's southern twin
North America isn't the only continent that's experienced super-colossal volcanic eruptions in the recent geologic past. The massive explosion of the almost unknown Vilama Caldera in Argentina appears to have matched Yellowstone's last continent-blanketing blast. It may, in fact, be just one of several unappreciated supervolcanoes hidden in a veritable mega-volcano nursery called the Eduardo Avaroa Caldera Complex, located in the inhospitable Puna-Altiplano region near the tri-section of Argentina, Bolivia, and Chile.
