The initial scale for measuring earthquake magnitudes was developed by Charles File. Richter in 1935. Subsequent scales (see seismic magnitude scales) have retained a vital attribute, where Every single unit represents a 10-fold difference within the amplitude of the bottom shaking, and also a 32-fold distinction in Strength.

While there's no these kinds of detail as a standard Price tag for earthquake retrofitting a home, the common selling price is often about 1 to 3 percent of the house's Price.
