Understanding Hazard Risk

The video discusses how natural disasters impact different regions based on hazard risk factors. It highlights the 2010 Haiti earthquake and compares it to Chile's experiences. The video covers three main factors affecting hazard risk: climate change, urbanization, and development level. Climate change increases the frequency and severity of weather hazards, urbanization raises risk due to higher population density, and lower development levels make regions more vulnerable. The video concludes with a call to action for viewers to engage with the content.

What was the estimated death toll from the 2010 earthquake in Haiti?

• 316,000

• 100,000

• 50,000

• 10,000

How many magnitude seven earthquakes has Chile experienced in the last hundred years?

• Two

• Eight

• Four

• Six

How does climate change affect the risk of natural hazards?

• It has no effect on natural hazards.

• It decreases the frequency of hazards.

• It only affects hazards in polar regions.

• It increases the frequency and severity of hazards.

What temperature is required for tropical storms to form?

• 20 degrees Celsius

• 15 degrees Celsius

• 27 degrees Celsius

• 30 degrees Celsius

How does urbanization impact hazard risk?

• It only affects rural areas.

• It has no impact on hazard risk.

• It increases the risk due to higher population density.

• It reduces the risk of natural hazards.

Which of the following is a characteristic of a highly urbanized area?

• Few buildings and roads

• High population density

• Limited infrastructure

• Low economic activity

What is a key difference between high-income and low-income countries in terms of hazard risk?

• Low-income countries have better emergency services.

• Low-income countries are more at risk due to weaker infrastructure.

• High-income countries have weaker buildings.

• High-income countries are more vulnerable to hazards.

What does LIC stand for in the context of development?

• Low Investment Country

• Low-Income Country

• Less Industrialized Country

• Limited Income Country

Why might hospitals in low-income countries struggle during natural disasters?

• They are located in safe areas.

• They are often poorly equipped.

• They have excess staff.

• They have too many resources.

What is the main purpose of understanding hazard risk?

• To identify why some areas are more affected by natural hazards.

• To predict the exact time of natural disasters.

• To ensure all countries have the same level of risk.

• To eliminate all natural hazards.
