What do you call the vibrations in the ground that result from movement along the breaks in Earth's crust and upper mantle?

• earthquakes

• seismograph

• epicenter

• fault

This was the first form of measurement of the strength of earthquakes.

• Richter Magnitude Scale

• Fahrenheit Magnitude Scale

• Seismic Magnitude Scale

• Mercalli Intensity Scale

This measures the intensity of an earthquake by observing its effect on people, the environment and the earth's surface.

• Richter Magnitude Scale

• Fahrenheit Magnitude Scale

• Seismic Magnitude Scale

• Mercalli Intensity Scale

This measures the energy released by a medium to small earthquake using only a seismograph.

• Richter Magnitude Scale

• Fahrenheit Magnitude Scale

• Seismic Magnitude Scale

• Mercalli Intensity Scale

A magnitude 6 earthquake produces how much more shaking than a magnitude 5 earthquake?

• 10

• 100

• 1024

• 32

This was designed to describe the effects of an earthquake, at a given place, on natural features, on industrial installations and on human beings.
