Scientists have discovered a potentially massive $1.5 trillion lithium deposit beneath the dormant McDermitt caldera, which could significantly impact the global supply of critical energy materials. The deposit, formed over 16 million years ago, is of strategic interest for the U.S. amid rising demand for lithium-ion batteries, but environmental, cultural, and technical challenges remain before extraction can proceed.
Scientists have confirmed the world's largest lithium deposit beneath Nevada's McDermitt Caldera, potentially holding over 20 million metric tons of lithium, which could significantly impact the US's clean energy and electric vehicle industries. The deposit's unique volcanic origin presents both opportunities and challenges, with ongoing debates over environmental and cultural impacts.
A massive lithium-rich clay deposit beneath the McDermitt caldera on the Nevada-Oregon border, valued at around $1.5 trillion, could significantly impact the global battery industry due to its size, high lithium concentration, and shallow depth, though environmental and cultural concerns pose challenges for extraction.
Recent advanced imaging studies have uncovered hidden magma reservoirs beneath Yellowstone, particularly in the northeastern caldera, raising concerns about potential increased eruption risks. While no immediate threat exists, a super-eruption could have significant local and global impacts, including ash fallout, climate cooling, and ecological disruptions. Ongoing monitoring and research are crucial for understanding and mitigating future risks.
Recent studies using advanced electromagnetic imaging have revealed multiple magma reservoirs beneath Yellowstone, shifting the focus of eruption risk to the northeast and highlighting the potential for a catastrophic super-eruption that could cause global climate cooling and widespread disruption, although such an event remains unlikely in the near future.
Aso Caldera in Japan is a massive, active supervolcano with a history of catastrophic eruptions, housing 17 volcanoes within its 15-mile-wide caldera, and poses ongoing geological and volcanic risks due to its active magma chamber and fault lines.
The Aso Caldera in Japan is a massive volcanic crater housing 17 volcanoes, including active ones like Nakadake, and is considered one of Earth's nine supervolcanoes, with a history of massive eruptions and located along the Pacific Ring of Fire.
Recent studies show that the unrest at Campi Flegrei is driven more by pressure in a sealed geothermal reservoir and hydrothermal activity than by magma movement, suggesting that managing water and pressure levels could mitigate eruption risks, although the volcano remains dangerous.
A recent USGS study reveals that Yellowstone's magma system is more complex than previously thought, with a 16% chance of a super-eruption before 2100, which could cause widespread ash fall, global cooling, and ecological disruption, emphasizing the need for improved monitoring and preparedness despite the low probability.
New research suggests that Kiladze, a feature on Pluto previously thought to be an impact crater, is more likely a caldera from a supervolcano eruption, indicating recent geological activity and potential residual warmth in Pluto's interior.
Scientists warn of a potential supervolcano eruption in the coming years that could cause catastrophic global effects, including climate cooling, widespread famine, and societal collapse, highlighting the urgent need for better preparedness and international cooperation.
Despite ongoing monitoring and large magma reserves beneath Yellowstone, scientists believe a super-eruption is unlikely in the near future, but if it occurs, it could cause widespread destruction, ash clouds, and significant global climate cooling, with potential impacts on agriculture and ecosystems worldwide.
Recent research shows Yellowstone's magma is concentrated mainly under the northeast of the caldera, with a significant volume that could potentially lead to a super-eruption, but such an event is not imminent, occurring roughly every 735,000 years on average. The eruption would cause widespread ash fall, pyroclastic flows, and global climate cooling, but warning signs might be minimal, making prediction difficult. The last super-eruption was 630,000 years ago, and while the impact would be catastrophic, the likelihood of an immediate eruption remains low.
Scientists warn that the Campi Flegrei supervolcano in Italy shows signs of awakening, with increased seismic activity, gas emissions, and ground swelling indicating magma is moving closer to the surface, raising the risk of a major eruption that could have devastating local and global impacts.
The Phlegraean Fields supervolcano near Naples is showing increased gas emissions and signs of instability, raising concerns about a potential eruption that could have catastrophic global consequences, prompting intensified scientific monitoring and preparedness efforts.
