The Seven Impacts of Earthquakes on Our World

The video discusses the seven effects of earthquakes: ground shaking, aftershocks, liquefaction, tsunamis, structural damage, fires, and human casualties. Each effect is explained with examples, highlighting the destructive power of earthquakes. The importance of being prepared and informed is emphasized.

What is the primary cause of buildings collapsing during an earthquake?

• Aftershocks

• Tsunamis

• Ground shaking

• Liquefaction

What are aftershocks?

• Large waves caused by undersea earthquakes

• Smaller earthquakes following the main event

• Soil turning into a liquid-like state

• Cracks in building foundations

What happens during liquefaction?

• Fires break out due to gas leaks

• Buildings are swept away by waves

• Soil loses strength and behaves like a liquid

• Structures collapse due to ground shaking

How are tsunamis related to earthquakes?

• They are caused by ground shaking

• They result from undersea earthquakes

• They are a type of aftershock

• They occur due to liquefaction

What type of damage is characterized by cracks in walls and foundations?

• Liquefaction

• Structural damage

• Aftershocks

• Ground shaking

What can cause fires during an earthquake?

• Ground shaking

• Tsunamis

• Aftershocks

• Damaged gas lines and electrical wires

What is a tragic consequence of earthquakes?

• Liquefaction

• Tsunamis

• Human casualties and injuries

• Ground shaking

What can ground shaking cause in terms of infrastructure?

• Tsunamis to form

• Soil to liquefy

• Fires to start

• Bridges to collapse

What is a potential effect of aftershocks on structures?

• They can cause fires

• They can further damage weakened structures

• They can create tsunamis

• They can prevent liquefaction

Why is it important to be prepared for earthquakes?

• They can strike at any time

• They can cause tsunamis

• They lead to liquefaction

• They always result in fires
