describe the tectonic setting of Italy
- volcanoes are clustered in the southern part of the country
- it has several fracture zones in the Mediterranean where the Eurasian and African plates meet
how many volcanoes have erupted in Italy in the past 100 years and which are these

which mount Etna eruption was the event significantly modified at
1993 eruption
which town was saved as a result of modifying the eruption of mount Etna in 1993
Zafferana
name three ways that the 1993 eruption of mount Etna was modified to save Zafferana
- barriers
- an artificial trench was created by the use of explosives to divert the lava’s pathway
- concrete blocks were dropped into lava to divert any flows that continued to move towards the town
name four ways that Italy modifies vulnerability to volcanic eruptions
- constant monitoring of active volcanoes
- a well established alert level system
- active community preparedness
- effective building designs to resist ash fall, such as pitched roofs instead of flat
what organisation in Italy makes important decisions, such as evacuation orders
the Volcano Risk Service
name three types of work conducted by the Italian Volcano Risk Service
- Long-term analysis of the eruption patterns of individual volcanoes
- international comparison with other similar eruptions
- Constant monitoring
name three ways that volcanoes can be monitored
seismometers, tiltmeters, and gas emissions
how does the Italian government modify loss
the Italian government has the resources and financial capability to compensate those who experience losses as a result of a volcanic eruption
what is Italy’s gdp
approx 1.9 trillion
how much does agriculture contribute to Italy’s GDP
