Earthquake and Tsunami Quiz

What is the main difference between earthquake magnitude and intensity?

• Magnitude measures the energy released, while intensity measures the earthquake's effects at specific locations

• Magnitude measures the shaking of the ground, while intensity measures the damage to structures

• Magnitude and intensity are the same thing

• Intensity measures the depth of the focus, while magnitude measures the depth of the epicenter

Which scale is used to measure the magnitude of an earthquake?

• Richter scale

• Mercalli scale

• Beaufort scale

• Saffir-Simpson scale

The Mercalli scale is used to measure:

• The depth of the earthquake

• The energy released by an earthquake

• The damage and effects of an earthquake on the Earth's surface

• The frequency of aftershocks

Which of the following best describes the Richter scale?

• It measures the intensity of the earthquake's shaking at a specific location

• It measures the depth of the focus

• It calculates the energy released from an earthquake

• It measures the volume of air displaced during an earthquake

What does a magnitude of 7 on the Richter scale represent?

• A weak earthquake with minimal damage

• A moderate earthquake with noticeable shaking

• A large earthquake that can cause major destruction

• A very minor earthquake only felt by a few people

Which scale is used to determine the intensity of an earthquake?

• Richter scale

• Moment magnitude scale

• Mercalli scale

• Seismic scale

An earthquake with a magnitude of 9 or higher is considered:

• Minor

• Moderate

• Major

• Great

Which of the following is an example of an effect measured by the Mercalli scale?

• The energy released by an earthquake

• The amount of structural damage caused by the shaking

• The distance between the epicenter and the focus

• The duration of seismic waves

How much more energy is released by an earthquake with a magnitude of 8 compared to an earthquake with a magnitude of 6 on the Richter scale?

• 10 times more

• 100 times more

• 1,000 times more

• 10,000 times more

The moment magnitude scale is used to measure the:

• Seismic waves' intensity

• Energy released by the earthquake at the source

• Damage to buildings and infrastructure

• Duration of the earthquake
