Mercalli scale has been in existence longer dating back to the 19th century. Its name comes from the modifications made to it in the 1890s by an Italian volcanologist, Giuseppe Mercalli. Ironically, it was Charles Richter who gave the scale its updated form which is used today, presently called the MMI scale, or known as the Modified Mercalli scale.
The Richter scale was developed in 1935 by Charles Richter, along with his associate, Beno Gutenberg, and today it is the commonly used scale in earthquake measurement. It was first developed for use in a particular area of California comparing the size of different quakes in the region. It was later adapted for use around the world. The Richter scale is more objective, but the Mercalli scale is subjective.
