- Mt Etna- 1991-93
- Thousands live on the slopes of the volcano and in the surrounding areas
- Fertile volcanic soils
- End of 91, lava began to pour from vents
- Protective measures
- Large earth barriers, which held back the lava for a few months
- Spring '92. Lava split over barrier, small barriers then built
- Split over the barriers and destroyed orchards and small buildings
- Concrete blocks dropped from helicopters through upper lava tube to block primary feeder channel
- May '92, engineers blasted openings in the lava tube. Create a new direction of flow.

- Schemes of success
- Low effusion rates during the eruption
- High elevation of the eruption vents
- Lava flow had to travel more than 8km before it became a serious threat
- Possibility of diverting the lava flow into uninhabited areas
