You are planning to move to a volcanic island and you want to choose the safest location. You have to decide between an island with a composite volcano consisting of dacite and andesite or an island with a shield volcano consisting of basaltic lava flows
Which island do you choose? Why?
What will be an ideal response?
You should choose the island with the shield volcano because lava flows usually advance slowly enough so that people can get out of the way. The pyroclastic flows and lahars associated with composite volcanoes move so rapidly that people in their path have little chance of survival.
