The difference between the Richter and Mercalli scales, both intended to measure earthquake severity, is that the Richter scale is a mathematical scale based on the measurements of scientific instruments, while the Mercalli scale is based on witness observation and structural damage.
It is not based on first physical principles, but is, instead, empirically based on observed effects. The Mercalli scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and man-made structures on a scale from I (not felt) to XII (total destruction). Values depend upon the distance from the earthquake, with the highest intensities being around the epicentral area.
