Earthquake Intensity and Magnitude Quiz

What does earthquake intensity measure?

• The total energy released by an earthquake

• The effects of an earthquake at a specific location

• The global distribution of earthquakes

• The depth of the earthquake

Which scale is used to express earthquake intensity?

• Amplitude scale

• Seismometer scale

• Modified Mercalli Intensity scale

• Richter scale

What factors influence earthquake intensity?

• Global distribution of earthquakes

• Depth, distance from epicenter, local geology, and building construction

• Magnitude and energy release

• Seismometer readings

How is earthquake magnitude different from intensity?

• Magnitude measures the global distribution, while intensity measures local effects

• Magnitude measures the depth of the earthquake, while intensity measures the shaking

• Magnitude quantifies the earthquake size and energy release, while intensity measures effects at a specific location

• Magnitude measures the effects at a specific location, while intensity measures energy release

What does earthquake magnitude measure?

• The depth of the earthquake

• The shaking felt at different locations

• The destruction caused by the earthquake

• The total energy released by an earthquake

Which scale is used to express earthquake magnitude?

• Modified Mercalli Intensity scale

• Richter scale

• Seismometer scale

• Amplitude scale

What does a 10-fold increase in amplitude on the Richter scale represent?

• A decrease in earthquake intensity

• A 10-fold increase in energy release

• A 10-fold increase in depth

• A 10-fold increase in shaking duration

What tools do seismologists use to calculate earthquake magnitude?

• Modified Mercalli Intensity scale

• Seismometers

• Building construction data

• Global distribution maps

How does magnitude affect an earthquake's potential for destruction?

• Larger magnitude earthquakes release more energy and can cause widespread damage

• Magnitude only affects shaking duration

• Smaller magnitude earthquakes cause more destruction

• Magnitude does not affect destruction

Where is the Ring of Fire located?

• Around the Atlantic Ocean

• Encircling the Pacific Ocean

• Near the Arctic Ocean

• In the Indian Ocean
