    The intensity level of an earthquake is based on the Richter scale. Using logarithms, the Richter scale measures an earthquake relative to (as a ratio of) the weakest possible tremor.

    -What is the formula for measuring earthquakes?
    -Why is a 7.0 earthquake ten times stronger than a 6.0 earthquake?

    Pick an earthquake in your region of the world.
    - Give the measurement of the earthquake. Explain what this measurement means.

    The actual formula for measuring earthquakes is:

    M = log A + (Distance correction factor)

    "M" is the magnitude.
    "A" is the amplitude (measured in millimeters) measured directly from the photographic paper record of the Wood-Anderson seismometer, a special type of instrument.

    The Richter Magnitude Scale "is a base-10 logarithmic scale obtained by calculating the logarithm of the ...
