Earthquake Quiz

What is an earthquake mitigation strategy?

• A method to predict earthquakes accurately

• A technique to prevent earthquakes from occurring

• A plan to minimize the damage caused by earthquakes

• A process to measure the intensity of earthquakes

How are epicenters of earthquakes located?

• By analyzing the magnitude of the earthquake

• By studying the frequency of aftershocks

• By measuring the depth of the earthquake

• By determining the location of the first P-wave arrival

What are the primary differences between P and S earthquake waves?

• P-waves are faster and can travel through solids and liquids, while S-waves are slower and can only travel through solids

• P-waves are slower and can travel through solids and liquids, while S-waves are faster and can only travel through solids

• P-waves can only travel through solids, while S-waves can travel through solids and liquids

• P-waves can travel through solids and liquids, while S-waves can only travel through solids

What are the dangers associated with liquefaction during an earthquake?

• Buildings can collapse due to the shaking of the ground

• The ground can become unstable and cause landslides

• Underground water can rise to the surface, causing flooding

• Soil and sediment can lose their strength and behave like a liquid

What does the Mercalli scale measure?

• The energy released by an earthquake

• The depth of an earthquake

• The magnitude of an earthquake

• The intensity of an earthquake based on observed effects

What does the Richter scale measure?

• The energy released by an earthquake

• The intensity of an earthquake based on observed effects

• The depth of an earthquake

• The magnitude of an earthquake

How is the intensity of an earthquake measured using the Mercalli scale?

• By calculating the total energy released by the earthquake

• By analyzing the amplitude of seismic waves

• By assessing the damage caused to structures and the environment

• By measuring the distance between the epicenter and the recording station

How is the magnitude of an earthquake measured using the Richter scale?
