Causes of the erruption
It was DESTRUCTIVE PLATE boundary.
The northern american plate (oceanic) subducted under the carabein plate
It melted and molten rock seeped through the surface
Forms a volcanoe
Phyroclastic flows formed and so did ash clouds
Ash and rock fell from the clouds 2-3mm fell onto the ground.
When was it?
Effects on the people
Sirens went off
People who were in the exclution zone (evacuated from the eruption in 1995) coudnt hear the sirens so didnt manage to evavuate.
7 people died
19 killed from strong winds
6 died from trying to find shelter
7,000 left from being worried that the erruption would happen again.
Effects on Transport
cut off from travel
destroyed Bramble airport
burnt tyers on cars
no one could be on the road because of the black cloud
cruse ships and tour buses lost money due to loss of tourists
Effects on the environment
Rivers got blocked and flooded
crops and vegitation were flattened by phyroclatic flow
4 squared meters was covered in deposits
5 million cubic meters was deposited like ash and rock from the ash cloud
phyroclastic flow filled valleys
long-term responses and results
- An exclusion zone was set up in the volcanic region.
- A volcanic observatory was built to monitor the volcano.
- New roads and a new airport were built.
- Services in the north of the island were expanded.
- The presence of the dormant volcano resulted in a growth in tourism.
