Mt Etna-management

Question 1

short term responses and precautions

Answer 1

drop concrete blocks-reduce lava flow emerging from volcano
spraying water on lava-cool and solidify lava higher up slopes so doesn’t reach settlements further down
explosives for diversion channels-controlled explosion set up by army to create deep channels to divert lava onto farmland
building earth diversion walls-bulldozers piled up ash and earth to form walls which divert lava onto farmland

Question 2

long term management

Answer 2

hazard mapping-work out where future lava flows are likely to go and ban building in those zones
monitoring seismic activity-attempt to predict future eruptions
thermal images- infra-red cameras measure surface heat using satellites=areas at risk can be evacuated
