Effects

Primary

  • Lava flow onto area immidiately surrounding the first fissure eruption.
  • Ash cloud from second eruption thrown up 5 miles into the atmosphere.

Secondary

  • The second eruption caused melt of the glacier. 1st day of 2nd eruption there were 2 flash floods damaging the main road around the island and stopping traffic.
  • THe ash covered the surrounding farmland forcing the farmers to move their livestock.
  • The ash that was thrown up into the atmosphere caused airspace over most of Europe to be closed, forcing people to be stranded abroad which cost companies £millions to try and get them home.
  • Businesses as employees were stranded abroad.

Positive Impacts

  • Fertile soils. Farmers to the south of the volcano reported record yields the following year
  • Because so many flights were grounded there was a huge decrease in CO2 emissions. An estimated 1.2 - 2.8 million tonnes of CO2 stopped from going to the atmosphere.
  • Coach + Cruise ship companies benefitted as they helped stranded people get home.
  • Some people enjoyed their extended holiday and werent too bothered about being stranded.
  • The tectonic activity in Iceland provides geothermal heating - so cheap energy, enabling farmers to heat greenhouses and outdoor thermal bathing
