Richter Scale

The Richter scale measures:

• the amount of radon gas released

• the movement of plates

• the strength of an earthquake

• the weight of tectonic plates

________________ measures the strength of an earthquake on a scale of 1-10.

• Seismometer

• Richter Scale

• Magnitude

• Seismology

What do we use to measure earthquakes?

• Richter scale and mercalli scale

• ruler and digital scale

• book and a wave machine

• Magnitude and longitude

Which scale measures the intensity of the ground movement?

• Mercalli Scale

• Richter Scale

• Seismogram Scale

• Bernoulli Scale

Which of the following is use to measure the earthquake’s magnitude?

• Richter Scale

• Modified Mercalli Scale

What does Richter scale in earthquake measure?

• Damage resulting from an earthquake

• Amplitude of seismic waves on seismogram

• Displacement on faults

Each higher number of the Richter scale

• increases with the magnitude of an earthquake

• means ten times more ground movement

• indicates about thirty times more energy released

• means all of the above

How is magnitude calculated?

• From a logarithmic measurement of the waves

• From the intensity and the damage caused to the land

• by an isoeismal map

• by interviews of people who experienced the earthquake
