Earthquake Impacts and Misconceptions

The video discusses earthquakes, their causes, and impacts. It explains primary and secondary impacts, such as building collapses and infrastructure damage. Methods to reduce impacts include aid, building design, and planning. The video also explores why people live in earthquake-prone areas, highlighting factors like government support and employment. It concludes with a summary and closing remarks.

What causes the vibrations felt during an earthquake?

• Heavy rainfall

• Volcanic eruptions

• Shock waves from tectonic plates

• Wind pressure

Which of the following is a primary impact of an earthquake?

• Economic recession

• Building collapses

• Government aid

• Waterborne diseases

What is a secondary impact of an earthquake?

• Landslides triggered by the earthquake

• Initial shock waves

• Immediate building collapse

• Electricity cables being damaged

How do earthquakes affect the economy in the long term?

• They boost local businesses

• They increase tourism

• They reduce government spending

• They lead to unemployment and repair costs

Why is it difficult to predict earthquakes?

• They are caused by weather changes

• They occur randomly without clear patterns

• They are influenced by human activities

• They are similar to volcanic eruptions

Which strategy is NOT effective in reducing earthquake impacts?

• Planning evacuation routes

• Designing earthquake-resistant buildings

• Educating the public

• Ignoring time scales of past earthquakes

Why do some people continue to live in earthquake-prone areas?

• They are forced by government policies

• They believe earthquakes are beneficial

• They have always lived there and rely on local employment

• They are unaware of the risks

What is a major challenge for LEDCs in dealing with earthquakes?

• Abundant healthcare facilities

• Excessive government funding

• Poor quality housing and infrastructure

• Advanced technology

How does poor infrastructure in LEDCs exacerbate earthquake impacts?

• It makes it harder to reach affected areas

• It speeds up recovery efforts

• It reduces the number of casualties

• It prevents building collapses

What is a common misconception about earthquakes in LEDCs?

• They are easier to predict

• They will not happen again soon

• They are less frequent than in MEDCs

• They have less severe impacts
