- test volcanoes
- perfect for analysis
- get data
- because there is a low population and so it does not harm anybody
- but, when aeroplanes go through an ash cloud, the engines stop working
- it chokes the engines
- plane starts to fall
- 'ring of fire'
- subductive boundary

- expensive but japan can afford it
- erupts continuously - tonnes of ash
- learning from historical documents can help predict when volcanoes erupt or how frequente they are likely to...
- HAZARD
- VDAP
- KRAFT
- document information about the volcanic destruction possible
- pyroclastic flow (extreme fast flow of lava)
- ash clouds? lahars?
- helps pre planning of an eruption
- Alaska
- 'ring of fire'
- MT. usu
- internatioanl analysis of possible eruptions
