      Reducing risks from earthquakes and volcanoes

      Lesson details

      Learning outcome

      I can explain why people continue to live in areas at risk from tectonic hazards and how management can reduce the effects of a tectonic hazard.

      Key learning points

      1. People continue to live in areas at risk from a tectonic hazard.
      2. Monitoring and prediction can reduce the risks from a tectonic hazard.
      3. Protection and planning can reduce the risks from a tectonic hazard.

      Keywords

      • Hazard risk - the likelihood or chance of being affected by a natural hazard, such as an earthquake or volcanic eruption

      • Management - techniques used to reduce hazard risk, including monitoring and prediction and planning and preparation

      • Monitoring - techniques used to detect and record indicators of earthquakes and volcanic eruptions

      Common misconception

      Because we know the location of plate margins, scientists can predict when earthquakes will happen.

      While scientists can identify areas that are at high risk of earthquakes, exact predictions for when and where an earthquake will occur (or what magnitude it will be) are not possible.

      Teacher tip

      Use real-world case studies to show how simple measures - like evacuation plans and building design- make a massive difference in disaster outcomes.

      6 Questions

      Q1.
      What is a natural hazard?

      A human-made disaster
      A climate event only
      Correct answer: A naturally occurring event that causes harm
      A hazard that happens in urban areas

      Q2.
      Which of the following is an example of a tectonic hazard?

      Flooding
      Correct answer: Earthquake
      Tornado
      Drought

      Q3.
      What causes volcanic eruptions?

      Weather patterns
      Correct answer: The movement of tectonic plates
      The melting of glaciers
      Human activity

      Q4.
      Which of the following can be a secondary effect of an earthquake?

      Ground shaking
      Landslides caused by rain
      Lava eruption
      Correct answer: Tsunami

      Q5.
      How do human activities increase the risk of natural hazards?

      By preventing them from happening
      By reducing the frequency of hazards
      By ignoring natural processes
      Correct answer: By creating conditions that worsen the impact

      Q6.
      What is the point on Earth's surface directly above where an earthquake originates called?

      Focus
      Correct answer: Epicentre
      Fault line
      Crater

      4 Questions

      Q1.
      What is one way to reduce the risk of earthquakes?

      Building structures in flood-prone areas
      Correct answer: Constructing buildings with flexible foundations
      Ignoring building regulations
      Allowing rapid deforestation

      Q2.
      Which of the following is a method to prepare for volcanic eruptions?

      Ignore evacuation plans
      Build on the slopes of volcanoes
      Correct answer: Monitor volcanic activity and issue warnings
      Encourage more tourism to volcanoes

      Q3.
      Why can't scientists accurately predict when an earthquake will happen, even though we know where plate margins are?

      Earthquakes are caused by weather changes
      Earthquakes only occur randomly
      Correct answer: Stress builds unpredictably along faults
      Plate margins are constantly moving at the same rate

      Q4.
      What is a common feature of earthquake-resistant buildings?

      Correct answer: Flexible foundations and shock absorbers
      Heavy, solid walls
      Large glass windows
      Minimal ventilation
