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 ten fold increase in the amplitude of seismic waves
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 Richter magnitude scale (ML) scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. It is a logarithmic scale based upon the horizontal amplitude of the largest displacement from zero on a seismometer. Each whole unit (i.e., 1.0) corresponds to an approximate energy increase of 32 time (e.g., a 6.0 M earthquake has 32 time the energy release of a 5.0 M).
Ten times
measurement of the amplitude of the largest seismic waves
The energy released by an earthquake increases by 10x for every 1.0 increase in magnitude on the Richter scale. A 6.2 quake is 2.0 higher than a 4.2 quake. The increase in energy output would be calculated as such: 10x10=100. A 6.2 magnitude earthquake is 100 times more powerful than a 4.2 magnitude earthquake.
A ten fold increase in the amplitude of seismic waves
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.
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 Richter scale provides a measure of the magnitude or energy released by an earthquake. It quantifies the amplitude (size) of seismic waves generated by the earthquake, which correlates with the earthquake's strength. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of shaking and approximately 31.6 times more energy release.
The Richter Scale measures the magnitude of an earthquake which is another way of describing the energy released in the earthquake.
The Richter magnitude scale (ML) scale, assigns a single number to quantify the amount of seismic energy released by an earthquake. It is a logarithmic scale based upon the horizontal amplitude of the largest displacement from zero on a seismometer. Each whole unit (i.e., 1.0) corresponds to an approximate energy increase of 32 time (e.g., a 6.0 M earthquake has 32 time the energy release of a 5.0 M).
The strength of earthquakes are measured by the Richter Scale. It is a base 10, logarithmic scale that measures the amplitude of the waves caused by an earthquake.
