Give 3 examples of how communities can prepare for the eruption of a volcano.

 Exclusion zone. Having an exclusion zone in predicted areas of pyroclastic flows can save many lives, like it did in the 1980 explosion of Mt St Helens. This meant that people were not allowed to go in the path of the flow, saving many lives.

Evacuation plans. The communities in the danger zone of pyroclastic flows by Mt Rainier, Washington have weekly earthquake drills where the sirens are sounded. There is a detailed evacuation plan for what people will do in the event of an emergency. This means that the movement of people is more efficient and lives can be saved.

Having a prepared aid response. If a pre-planned aid response has been formulated, it means that if a disaster is to happen, that the aid response will be a lot quicker and more organised, potentially saving many lives. An example of when this was not the case, was in the 1985, Nevado Del Ruiz earthquake in Columbia. The badly coordinated response effort meant that many lives were lost which could have been avoided.
