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

Ten times.

It was a pretty terrible event that affected thousands of people. It can be confusing talking about the magnitude of an earthquake as different countries can use different scales (Japan uses a different one from the international standard as one example). The 28 March earthquake was Magnitude 8.6 as measured in Northern Sumatra, Indonesia at 4.09 pm in 2005. The extra energy release to go further up the scale is exponential (meaning that a magnitude 2 earthquake is much more than double the energy of a magnitude 1 earthquake).

a magnitude 7.2 earthquake produces 10 times more ground motion than a magnitude 6.2 earthquake, but it releases about 32 times more energy. The energy release best indicates the destructive power of an earthquake.

The magnitude measures the total energy release. The intensity measures the... well, the instantaneous "shock" felt by an observer.

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).

Intensity is a measurement of the ground acceleration and damage caused by an earthquake. The Richter scale is infact a magnitude scale (it measures the amount of energy released by an earthquake). A magnitude 5.0 earthquake will have seismic waves with an amplitude 1000 times larger than a magnitude 2.0 earthquake and will release approximately 31,600 times more energy.

The Richter Magnitude Scale. 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 approximately 31.6 times greater than one that measures 4.0 The same applies comparing a 4.0 to a 3.0, a 6.0 to a 5.0, and so on.

Each increase by one magnitude corresponds to a release of energy 31.6 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has roughly 1/31554th the energy of the magnitude 7.Each increase by one magnitude corresponds to a release of shaking amplitude 10 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has 1/1000th the shaking amplitude of the magnitude 7.The amount of energy changes much more rapidly with magnitude than the amount of shaking amplitude. This is a commonly made error.

Seismic energy increases by a factor of about 31.6 for each increase of magnitude, so a magnitude 3 earthquake has 31.6 times more energy released than a magnitude 2 earthquake.

An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Earthquakes are recorded with a seismometer, also known as a seismograph. The moment magnitude of an earthquake is conventionally reported, or the related and mostly obsolete Richter magnitude, with magnitude 3 or lower earthquakes being mostly imperceptible and magnitude 7 causing serious damage over large areas. Intensity of shaking is measured on the modified Mercalli scale.

Every change of 1 on the Richter scale increases the amplitude of the measured seismic waves of the earthquake by a factor of 10 and the energy released scales with the shaking amplitude based on the following: Change in energy released = (10^Md)^(3/2) Where Md = difference in magnitude between two earthquakes (in the example above this is 3.0) Therefore a magnitude 6.0 earthquake releases (10^3.0)^(3/2) = 31,622 times more nergy than a magnitude 3.0 earthquake and has seismic waves with 1000 times larger amplitude.

The richter scale is used by scientists to measure the amount of energy release by an earthquake.

The Richter Scale is a Magnitude scale - it is used to calculate the magnitude of small and medium sized earthquakes (those with a magnitude less than 7). The other scales most commonly used for recording Earthquakes are the Moment Magnitude Scale and the Modified Mercalli Intensity Scale.The Intensity scale of the Earthquake measures the effect of the earthquake at a particular location. In general it is highest at the epicenter and gets lower as you go further. The value of intensity changes from place to place.The Moment Magnitude scale measures the actual amount of energy released during the Earthquake and is derived based on the rigidity / stiffness of the crust, the length of fault that slipped and it's cross sectional area.An Earthquake has only one value of magnitude, and it does not change from place to place. The scale is logarithmic.However the now outmoded Richter Scale used a different method of deriving the energy release based on the maximum amplitude of the seismic waves detected on seismometers. As such it was a measurement of the local magnitude (i.e. local to the seismometer) rather than the absolute magnitude of the earthquake.
