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.
Comparison to the moment magnitude scale[edit] The effects of any one earthquake can vary greatly from place to place, so there may be many Mercalli intensity values measured for the same earthquake. These values can be best displayed using a contoured map of equal intensity, known as an isoseismal map.
