- Fissure eruption, lava flow dominant on west
- Ash plume 11,000m (36,000ft) into the air
- Fine grained ash distributed by high speed jet stream
- Local Effects
- 150m thick ice cap melted causing flooding (700 people evacuated
- Main roads destroyed, some roads bulldosed to allow flash flood to reach the sea
- Fine ash silted rivers so blockages occured
- Government paid for dredging/ flooding to make new paths
- 20 farms destroyed
- Worldwide Effects
- Fine ash = turns into a glassy substance when in plane engines
- Engine heat causes this
- UK had anticyclonic weather so ash was dispersed better
- 95,000 flights cancelled, 6 flightless days
