Q

What happens on a constructive plate boundary?

A

The two plates move apart due to ridge push where as the plates move apart magma fills the magma chamber.

Q

What were the social primary effects?

A
  • Day turned to night as the ash blocked the sun.

Q

What were the economic primary effects?

A
  • European airspace was brought to a standstill, costing billions of euros in delays.
  • Airlines lost around £130m per day due to the no-fly zone across much of Europe.
  • The price of shares in major airlines dropped between 2.5 and 3.3%.
  • Imports and exports across European countries were disrupted, but the net trade position remained relatively unaffected.

Q

What were the secondary effects?

A
  • Sporting events were cancelled or affected due to cancelled flights.
  • Fresh food imports stopped, and industries were affected by a lack of imported raw materials.
  • Local water supplies were contaminated with fluoride.
  • Flooding was caused as the glacier melted.

Q

What were the international effects?

A

The eruption affected Kenya’s horticulture industry, with 5,000 workers laid off as flowers and vegetables rotted at airports. Kenya lost $1.3m daily in exports to Europe, where 97% of its 500 tonnes of daily flower exports are sent. In 2009, horticulture, Kenya’s top foreign exchange earner, generated 71 billion shillings (£594m).

Q

What opportunities did the eruption of E15 bring?

A
  • The grounding of European flights prevented 2.8 million tonnes of carbon dioxide emissions.
  • Alternative transport modes, such as Eurostar, saw increased demand, with passenger numbers rising by nearly a third (50,000 extra passengers).
  • Ash from the eruption deposited dissolved iron into the North Atlantic, triggering a plankton bloom and boosting biological productivity.
  • Iceland launched the Inspired by Iceland tourism campaign to counter negative publicity, promoting the country’s beauty and hospitality.
  • Tourism in Iceland increased significantly as a result of the campaign.
18
Q

What was done to reduce the impact of the eruption of E15?

A
  • The area around the volcano was evacuated, with 700 people evacuated three times within a month, including during nighttime flash floods.
  • The European Red Cross provided food, counselling, and psychosocial support, especially for traumatised children in farming communities near the glacier.
  • The European Union implemented a new air traffic management structure, reducing 27 airspace zones to nine Functional Airspace Blocks (FABs), aiming to limit airspace closures during future volcanic eruptions.
