- Soufriere Hills 1997 Volcanic Eruption
- June 25, 1997
- 19 deaths
- 7 injuries
- Causes
- Destructive plate margin:Carribean Plate subduing AtlanticPlate
- Magma Rose up through weak points, creating pool of magma.
- Rocks collapse above pool, opening vent for eruption
- Magma Rose up through weak points, creating pool of magma.
- Destructive plate margin:Carribean Plate subduing AtlanticPlate
- Impacts
- Ash
- Plymouth covered in 15m
- Pyroclastic Flow
- 20 villages
- 2/3 homes
- 2/3 lof population left island since 1997
- Volcanic ash increase soil fertility
- Tourism increasing to see volcano
- Islanders evacuated from south to north
- Montserrat Volcano Observatory to predict future eruptions.
- UK gave £58m for aid
- Ash
- Volcanic Explositivity Index: 3/8 (moderatley large)
