'No preparation for civilization

Key Points:

• A Cambridge University study warns that the threat of a supervolcano eruption is significantly underestimated, with a one-in-six chance of a magnitude seven eruption occurring this century, potentially causing severe global disruptions to supply chains, climate, and food supplies.
• Such an eruption would have impacts comparable to a 1km-wide asteroid strike, yet governments invest far more in asteroid preparedness than in volcanic eruption readiness, highlighting a critical gap in global disaster planning.
• Historical data shows that eruptions 10 to 100 times more intense than the 2022 Tonga eruption occur roughly every 625 years, with the last magnitude seven event in 1815 causing massive loss of life, global cooling, agricultural failures, and widespread social unrest.
• Researchers emphasize the urgent need for better monitoring, public education, and volcanic risk mitigation strategies, noting that many potentially dangerous volcanoes remain unidentified due to insufficient geological research.
• Experts caution that modern society's increased population and complex global trade networks could amplify the catastrophic effects of a supervolcano eruption, making enhanced preparedness and funding essential to prevent a planetary-scale disaster.
