The challenge of natural hazards: Natural hazards -Reducing The Risk

Question 1

Monitoring

Answer 1

Looking for warning signs from volcanoes – changes in shape, gases released etc. Warning signs for earthquakes are more difficult, small changes in water pressure, ground shape and minor tremors can be felt.

Question 2

Prediction

Answer 2

Scientific monitoring can help predict volcanic eruptions. Earthquakes are more difficult to predict as there is very little warning.

Question 3

Protecting

Answer 3

Volcanoes are difficult to control; embankments can be created to divert lava. Earthquake protection is the main way to reduce risk. Buildings and bridges built to resist ground shaking.

Question 4

Planning

Answer 4

Areas to be evacuated in the event of volcanic eruptions have been identified. High risk areas are identified in earthquake zones and high value land uses are protected in those areas.
