HAZARDS EXAMPLE PHOTO Lava flows burn and bury crops. Mount Merapi‚ Indonesia - More than 350 people were killed. An estimated 75‚000 residents had been evacuated from the area between October to November 2010. Ash falls ruin crops and machinery‚ disrupt transport‚ pollute the air and cause breathing difficulties. Mount Etna‚ Italy - Grapes needed to be washed individually before consumption to avoid ingesting fine ash. This effectively ruined the grape crop economically‚ even though the
