Economic Impact of a Yellowstone Volcano Eruption

Economic Impact of a Yellowstone Volcano Eruption A super-eruption of the Yellowstone volcano would have catastrophic economic consequences worldwide, with estimated costs exceeding $3 trillion. Immediate Impacts Agricultural Sector: Volcanic ash would devastate crops within a 1,000 km radius, causing agricultural losses of $300-500 billion annually. Grain production in the US Midwest would collapse. Air Transport: Total suspension of North American air traffic for weeks, with losses of $50-100 billion. International flights would be severely affected. Energy: Massive power outages due to infrastructure damage, costing $200-400 billion in repairs and lost production. Long-Term Effects Climate Change: Global cooling for 2-10 years would reduce global GDP by 10-17%, equivalent to a prolonged economic depression longer than the 1929 crisis.
