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)

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)

Study suggests ample warning of supervolcano eruptions
Concern over the potential imminent eruptions of Earth's supervolcanoes, like Taupo in New Zealand or Yellowstone in the United States, may be quelled by the results of a new study suggesting that geological signs pointing to a catastrophic eruption would be clear far in advance. (2018-04-30)

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: 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)

Supervolcanic ash can turn to lava miles from eruption, MU scientists find
University of Missouri scientists determine that ash can turn back into lava miles away from a supervolcano eruption due to reheating by a process called (2013-08-27)

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)

Italy honors supervolcano fossil discovery; Capellini Medal to SMU's James Quick
Italian geologists in September will award the Capellini Medal to Southern Methodist University scientist James E. Quick, recognizing discovery of an enormous 280 million-year-old fossil supervolcano in the Italian Alps. Its magmatic plumbing system is exposed to an unprecedented depth of 25 kilometers. The discovery has sparked worldwide scientific interest and a budding regional geotourism industry in northern Italy's Sesia Valley. Quick led scientists from the University of Trieste to make the discovery. (2010-09-02)

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. (2006-03-28)

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)

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)

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)

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)

EARTH: Do-it-yourself lava flows
It's not every day that lava flows through a college campus parking lot. But, since January 2010, Syracuse University has been bringing the lava to Central New York. Using commercially available basalt gravel and a coke-fired furnace, the geologists involved with the Syracuse University Lava Project are able to produce a wide range of flow morphologies and other features at a scale comparable to natural flows.

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?
