The year 536 CE was one of the worst times to be alive due to a massive volcanic eruption that caused a 'volcanic winter,' leading to drastic climate changes, crop failures, famine, and pandemics, significantly impacting the course of history especially in Europe and the Middle East.
New research suggests that a platinum spike found in Greenland's ice core around 12,800 years ago, previously thought to indicate a meteorite impact, was likely caused by a volcanic fissure eruption in Iceland, which may have contributed to the climate cooling during the Younger Dryas period, rather than an extraterrestrial impact.
A mysterious platinum signature found in Greenland's ice, previously thought to indicate a space impact, is now attributed to a volcanic eruption in Iceland, which may have contributed to the onset of the Younger Dryas cold period, highlighting the role of volcanic activity in past climate shifts.
The 2025 volcanic crisis at Santorini and Kolumbo revealed a coupled magma system with a significant dike intrusion and seismic swarm, indicating complex interactions between the volcanoes' magmatic and tectonic systems, emphasizing the importance of integrated real-time monitoring for hazard assessment.
New research suggests that a platinum spike found in Greenland's ice core around 12,800 years ago, previously thought to indicate a meteorite impact, was likely caused by a volcanic fissure eruption in Iceland, which may have contributed to the onset of the Younger Dryas cold period by releasing sulfur and heavy metals into the atmosphere. This finding challenges the impact hypothesis and highlights the role of volcanic activity in past climate shifts, emphasizing the importance of understanding such events for future climate predictions.
After a 2013 volcanic eruption nearly wiped out all life on Nishinoshima, scientists used DNA analysis to discover how plants, specifically purslane, recolonized the island through a founder effect, likely arriving via ocean currents, wind, or birds, highlighting the resilience of ecosystems on active volcanic islands.
Tokyo officials released AI-generated videos simulating a Mount Fuji eruption to prepare and inform residents about potential volcanic hazards, despite no signs of imminent activity, aiming to enhance disaster readiness among Tokyo's 37 million residents.
Japanese officials released AI-generated videos simulating a potential eruption of Mount Fuji to prepare Tokyo residents for a possible disaster, despite no signs of an imminent eruption, which has caused some public anxiety.
Japan's government released an AI-generated video to simulate a Mount Fuji eruption, aiming to raise awareness and preparedness among Tokyo's 20 million residents, highlighting potential hazards like ash clouds, power outages, and transportation disruptions, despite no imminent eruption warning.
Iceland's latest volcanic eruption, the 12th since 2021, features a 2.4 km fissure spewing lava, captured dramatically by drone footage, with ongoing lava flows and minor seismic activity, posing local risks from wildfires and toxic gases.
A volcanic eruption occurred on July 16 in Iceland's Sundhnúkur crater row following an earthquake swarm, with lava erupting from a large fissure and spreading to a second, while authorities monitor gas pollution and environmental impact; the eruption is ongoing but poses no immediate threat to infrastructure.
Scientists have uncovered that the prolonged super greenhouse conditions after the Permian–Triassic extinction were caused by the destruction of tropical forests, which normally help regulate Earth's carbon cycle. The volcanic eruptions in Siberia decimated these forests, reducing the planet's ability to absorb carbon and prolonging the hot, uninhabitable state for millions of years. Recovery was slow, with only small plants initially recolonizing the land, delaying the stabilization of Earth's climate.
Scientists warn that a major volcanic eruption could cause severe climate chaos, especially in a warming world, with historical precedents and future risks highlighting the need for better prediction models and preparedness to mitigate potential 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.
Scientists have discovered that seismic waves detected 15 minutes before the massive 2022 eruption of the Hunga Tonga Hunga Ha’apai volcano could serve as an early warning system for future eruptions. The seismic activity, recorded by stations in Fiji and Futuna, was linked to a fracture in the oceanic crust, allowing magma and seawater to mix and build explosive pressure. This finding suggests that similar seismic signals could help predict eruptions, especially in remote oceanic areas, potentially mitigating disaster impacts.
