The modified mercalli intensity scale is used to measure the intensity of an earthquake and is in part derived from the damage done to building and other structures. Edit Share to:
The magnitude of an earthquake is a Logarithmic scale. The famous Richter Scale uses this formula: M = log 10 A + B. Where A is the amplitude (in mm) measured by the Seismograph. and B is a distance correction factor. Nowadays there are more complicated formulas, but they still use a logarithmic scale.
