The California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time. Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size.

The Modified Mercalli Scale (1931) of earthquake damage measures the intensity of an earthquake at a particular place. It uses the type and amount of damage. It uses the type and amount of damage. Unlike the Richter Scale, it does not measure the absolute strength of the earthquake but how strongly it is felt at a particular place.
