- Yellowstone supervolcano
- A supervolcano is much larger than a normal volcano. they emit at least 1000 cubic metres of material.
- The magma chamber is believed to be 80km long, 40km wide and 8km deep
- Eruptions have occurred at Yellowstone 2 million years ago, 1.3 million years ago and 630,000 years ago which suggests we are due another one.
- The Yellowstone caldera is located in Yellowstone national park in Wyoming near the border of Idaho.
- Potential impacts
- If an eruption was to occur at Yellowstone the effects would be catastrophic worldwide as it is potentially five times the minimum size for a super vocano.
- An eruption of Yellowstone is likely to destroy 10,000 square km of land, kill around 87,000 people and cover buildings within 1000km in 15cm of ash.
- Within in a 1000km radius, 1 in 3 people would die directly due to the ash as it can turn to cement like rock when it comes into the contact with liquid in their lungs.
- The ash would affect electricity, water, transport and farming.
- International airlines would be seized leaving many stranded without shelter.
- The ash cloud would throw the world into a volcanic winter as climates would change dramatically.
- Crops would fail and many people would die from starvation.
- Lahars (mudflows) are a possibility causing further turmoil.
- The worlds markets would crash forcing many countries and people into poverty.
