Earthquake Intensity Quiz

What is seismic intensity?

• The distance from the earthquake's hypocenter

• The energy released by an earthquake

• The shaking experienced during an earthquake

• The depth of the earthquake's epicenter

What does earthquake magnitude measure?

• The distance from the earthquake's hypocenter

• The depth of the earthquake's epicenter

• The shaking experienced during an earthquake

• The energy released by an earthquake

What does the intensity of ground shaking depend on?

• The type of local rock and soil

• The distance from the hypocenter

• The earthquake's magnitude

• The earthquake's depth

What does the Modified Mercalli Intensity Scale reflect?

• The shaking experienced during an earthquake

• The energy released by an earthquake

• The depth of the earthquake's epicenter

• The effects of an earthquake

What is the purpose of a ShakeMap?

• To measure earthquake magnitude

• To illustrate the intensity of ground shaking

• To predict the occurrence of earthquakes

• To analyze the depth of earthquake epicenters

How does earthquake magnitude affect the intensity of ground shaking?

• Lower magnitude leads to greater intensity everywhere

• Magnitude only affects the depth of the earthquake's epicenter

• Higher magnitude leads to greater intensity everywhere

• It has no effect on ground shaking intensity

What pattern does the intensity of ground shaking follow with distance from the earthquake's epicenter?

• It remains constant regardless of distance

• It is random and unpredictable

• It decreases with distance

• It increases with distance

How does the depth of an earthquake's hypocenter affect ground shaking intensity?

• Hypocenter depth only affects the earthquake's magnitude

• Depth has no effect on ground shaking intensity

• Shallower hypocenter leads to greater intensity

• Deeper hypocenter leads to greater intensity

What factor strongly influences ground shaking intensity and potential damage?

• The depth of the earthquake's epicenter

• The distance from the hypocenter

• The type of local rock and soil

• The earthquake's magnitude

What immediate action can save lives and reduce the risk of injury during an earthquake?

• Run outside immediately

• Stand near a doorway

• Try to move heavy objects to safety

• Drop, Cover, and Hold On
