MEDC Volcano Case Study:
Eyjafjallajökull, Iceland
- Causes
- 20th March 2010
- Stratovolcano
- Also sits on a hotspot-more destructive
- Sits on top of the Mid-Atlantic
Ridge-constructive plate boundary
- Eurasian plate and North
American plate moving apart
- Impacts
- Social
- Ash from eruption got caught in the Jetstream
where most planes use as a fast way of
travelling
- Most major
airports in Europe
shut for 4 days
- Losing £10 million per day due to lack of tourism
- Fresh fruit and veg, organ donations etc couldn't be transported
- Ash in jet engines causes glass type
substance to form inside the engines.
- Evacuation of around 500 people living nearby
- Eruption has made it into a tourist attraction
- Environmental
- Melted glacier caused
flooding
- Mudflow from meltwater flowing down the
side of the volcano
- Ash clouds spread for mile affecting many
countries
- Agricultural land damaged by ash
- Contaminated water
supplies-health risk on farm
animals
- Hazards
- Volcanic ash erupted into atmosphere 5 miles up
- Eruption happened on bare flank of the volcano
- Crater buried under 700 feet of ice-created
plug in crater
- Magma became more
viscous
- Eruption of crater melted glacier
- Managemant
- Prediction
- Geologists were able to predict the eruption
- Slopes becoming steeper indicates
eruption
- Protection
- People evacuated from local areas
- Warning systems such as the text message system whereby a
text is sent to warn people 30 mins away from the volcano
when it is about to erupt
- Prevention
