There are a number of reasons why some places are more at risk of experiencing a major volcanic disaster. One reason is their geographical position within the world and in relation to tectonic plate boundaries. For example you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone.

Another reason why some places are more a risk than others is because of their prediction and evacuation systems. In poorer countries such as Indonesia they don’t have the equipment or expertise to predict earthquakes and they don’t have the media to broadcast potential volcanoes and this leaves these places more at risk than places such as Iceland which have better prediction, planning and preparation and this leaves them less chance of experiencing a major volcanic disasters.
