Well for measuring the intensity/magnitude of an earthquake we usually use Mercalli's intensity scale.


  • For weak earthquakes we usally use a manner in which the earthquake is felt by people as a measure.

  • The higher numbers of the scale are based on observed structural damage.

You can check the Mercalli's intensity scale here:

  • Who is Mercalli?

  • Giuseppe Mercalli (May 21, 1850 – ✝March 19, 1914) was an Italian* volcanologist and Catholic priest.
    He is well remembered of his Mercalli intensity scale with which we measure the intensity of earthquakes.
