• 1931

• 1989

On the Richter scale what does the measurement increase by when the measurement goes up one whole number?

• factor of 30

• factor of 10

• factor of 100

• factor of 900

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

Which is more useful to measure the impact of an earthquake?

What is the range for the Mercalli intensity scale?

• l to Xll

• l-X

• 1-10

• infinity

What is intensity?

• the measure of impact and damage the earthquake had

• the measurement of energy released from the earthquake

• the measurement of waves from an earthquake
