Dec 03, 2021 There are two commonly used scales to rate the strength of an earthquake, 1) the Richter Scale and 2) the Mercalli Scale. The force of an earthquake is measured using the Richter Scale, which rates the amplitude of the waves — as measured on a seismograph — on a scale from 1 (pounds of movement) to 9 (tons of movement).

A short wiggly line that doesn’t wiggle very much means a small earthquake, and a long wiggly line that wiggles a lot means a large earthquake. The length of the wiggle depends on the size of the fault, and the size of the wiggle depends on the amount of slip. The size of the earthquake is called its magnitude.

– The common earthquake Richter Scale is a measure of how much ground movement a local earthquake produces. For example, an R=5.0 earthquake produces 10 times more ground movement than an R=4.0 earthquake. This scale is calibrated so that an R=0 earthquake at a distance of 100 km produces a ground change of 1 micron (10
