I assume that you mean the Richter scale and not richer scale. The Richter scale is a logarithmic (base 10) scale. An increase in magnitude of 2 represents an increase in amplitude by a factor of 100.
the magnitude of 3.0 releases about 1000 times as much energy as an 1.0 magnitude
The expression Richter Magnitude Scale refers to a number of ways to assign a single number to quantify the energy contained in an earthquake.In all cases, the magnitude is a base-10 logarithmic scale obtained by calculating the logarithm of the amplitude of waves measured by a seismograph. An earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger and corresponds to an energy release of √1000 ≈ 31.6 times greater than one that measures 4.0.[1]Since the 1970s the use of the Richter Magnitude Scale has largely been supplanted by the moment magnitude scale
Seismic waves are the vibrations from earthquakes that travel through the Earth; they are recorded on instruments called seismographs. Seismographs record a zig-zag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs, which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. The time, locations, and magnitude of an earthquake can be determined from the data recorded by seismograph stations. The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs.
It reached 7.0 on the richter scale
The Richter scale is based on measurements of *Amplitude*. (^_^)
the Richter scale depends on the amplitude of the largest seismic wave recorded on a seismogram . A ten-fold increase in the amplitude is registered as an increase of 1 on the Richter scale.
The change in magnitude is (6.2 - 4.2) 2.0. This is equivalent to a 100 times increase in seismic wave amplitude (as each increase of 1 on the scale is a 10 times increase in amplitude therefore 10 * 10 = 100)..
A magnitude scale is simply a metric for quantifying the energy released in an earthquake and the amplitude of the waves the earthquake emits. The most well-known magnitude scale in America is the Richter scale, which is equated in base 10 (that is, an earthquake that scores 5.0 on the Richter scale will have an Amplitude ten times greater than that of an earthquake that scores a 4.0 on the Richter scale).
The Richter magnitude scale is a base-10 logarithmic scale of the shaking amplitude. This means that a difference of 1 in the scale is equivalent to a 10-fold increase in amplitude. So the difference in amplitude between a mag 8 and a mag 4 earthquake is 104.

An earthquake is measured by a seismometer to determine its magnitude on the Richter Scale. The Richter is based on a base 10 logarithm. The scale defines magnitude by a logirithm of the ratio of the amplitude of seismic waves.
The Richter Scale is used to rate the magnitude of an earthquake -- the amount of energy it released. This is calculated using information gathered by a seismograph. The Richter Scale is logarithmic, meaning that whole-number jumps indicate a tenfold increase.In this case, 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. The amount of energy released increases 31.7 times between whole number values.
Richter scale measures the ground motion from an earthquakes to find the earthquakes strength. mercalli scale measures expresses intensity in roman numerals from I to XII and provides a description of the effects of each earthquake intensity.
The severity of earthquakes is typically measured using the Richter scale or the moment magnitude scale. The Richter scale measures the amplitude of seismic waves and assigns a numerical value, while the moment magnitude scale measures the total energy released by an earthquake. Both scales are logarithmic, meaning that each whole number increase in value represents a tenfold increase in the amplitude or energy release.
Its because of the amplitude shown on a seismograph according to the Richter scale.
