Question

An intensity scale known as the Mercalli Scale, and later the Modified Mercalli Scale, has been made obsolete by modern technology and primarily replaced by what other, logarithmic scale, developed in 1935?

Answer 1

The Mercalli Scale was replaced by the Richter Scale, also known as the Local Magnitude Scale, which was developed in 1935 by Charles Richter. The Richter Scale measures the magnitude of an earthquake by calculating the seismic waves' amplitude, and it is logarithmic, meaning that a one-unit increase on the scale corresponds to a tenfold increase in ground motion. While the Modified Mercalli Scale is still used to assess the intensity of an earthquake's effects on people and structures, the Richter Scale provides a more accurate measurement of an earthquake's strength.
