How can risks of volcanic erruptions be reduced?
MONITOR - satellites can be used to detect surface shape changes of a volcano. Gas levels can be monitored. Surface temperature can be monitered and will get hotter when magma is rising to the surface
PREDICTION - Tectonic plate movement can be monitored and time since the last erruption may show patterns to predict when the next one will happen - this will alow people to evacuate
PROTECTION - evacuate all residents in an area where lava and air quality is harmful
PLANNING - evacuation plan, have emergency supplies and shelter planned, educate local people on actions they can take to reduce the loss of life
