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.
The Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake is 10 times greater than in a level 5 earthquake, and the amplitude increases 100 times between a level 7 earthquake and a level 9 earthquake.
