What is measured with the Richter scale?

Explanation

The Richter magnitude scale is used to quantify the size of an earthquake. The scale was invented by the seismologist Charles Francis Richter in California in 1935. The scale measures the power of the vibrations to determine how powerful an earthquake is. In its original definition, the Richter scale was a base-10 logarithmic scale. This means that for every step on the scale, the amplitude of the vibration increases 10-fold.
