When referring to earthquakes what is the difference between the Magnitude scale and the Richter scale?
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.

How is the magnitude of earthquakes calculated?
The moment magnitude scale (MW) provides an estimate of the total energy released in an earthquake and is currently the preferred magnitude scale in use by seismologists .It is calculated from the seismic moment (M0 - which has the unit of dynes/cm =where 1 dyne/cm = 1x10-7 N/m) which is a measure of the total energy released during an earthquake and is derived based on the elastic moduli of the crust where the earthquake occurred, the length of the slip surface and the cross sectional area of the slip surface as follows:M0 = G x AFx DFWhere:G = Shear modulus of the rock massAF = Area of the rupture along the faultDF = average displacement on AFIn order to make the moment magnitude scale (Mw) consistent with older magnitude scales such as the Local Moment (or "Richter") scale the seismic moment (M0) is converted into a logarithmic scale using the following equation:Mw = 2/3 x log10 x (M0) - 10.7This ultimately yields a dimensionless number and as such, Moment Magnitude has no units.Please see the related question.
Scale used to measure earthquakes?
The oldest scale of measurement for earthquakes were in fact intensity rather than magnitude scales with the first being The Mercalli intensity scale. Intensity scales describe the earthquake in terms of the damage caused. Later, improved versions of this form of measurement were published in 1931 as the Mercalli-Wood-Neumann scale.The first widely accepted magnitude scale (magnitude being a description of the energy released by an earthquake) was developed by Charles Richter in 1935. This was known as the Richter magnitude scale (also known as the Local Magnitude Scale), which categorises them in absolute terms based on calculating the logarithm of their amplitude and the distance of the seismometer station from the epicentre. The Richter scale was designed to measure the magnitude of moderate and small earthquakes. The scale has no theoretical upper or lower bounds, however in practical terms the lower bound is defined by the minimum sensitivity of seismometers and their ability to detect small earthquakes and the upper limit (effectively around a magnitude of 7.0) is due to the fact that earthquakes larger than this due to the wavelength of seismic waves produced by large earthquakes.In order to attempt to overcome this, Charles Richter along with his colleague Beno Gutenberg developed the surface and body wave magnitude scales. These produce results that are consistent with the original magnitude scale and extend it's utility up to earthquake with a magnitude of 8.0For earthquakes larger than magnitude 7-8 a new scale was required and this was developed in the 1970s and is known as the Moment Magnitude Scale (MMS) which measures the earthquakes magnitude based on the length of the fault that slips, the amplitude of the fault movement and the elastic moduli of the rockmass around the fault zone.The modern scale retains the familiar logarithmic continuum of values with the original Richter (local) magnitude scale.

What is the magnitude and length and damage of the 1927 china earthquake?
what was the magnitude of China's earthquake in 1927 the magnitude was long
What is the magnitude length and damage of China's 1927 earthquake?
The magnitude of the 1923 Tokyo earthquake was 7.9 on the Richter scale. Length of quake: 4-10 minutes. Overall, estimated damage included the loss of 570,000 residences and a cost in excess of one billion U.S. dollars in today's figures. There were 105,000 confirmed deaths, and another 40,000 or so who went missing.
What is the average length earthquake?
about 2 to 4 minutes depending upon the magnitude
The earthquake which struck Haiti was recorded as magnitude 7.0 what does this mean?
Magnitude is a term used to describe how much energy was released by an earthquake. It gives an indication of the amplitude of the seismic waves that occur and also on the length of the fault rupture zone and the displacement along the fault. A magnitude 7 earthquake is defined by the US Geological Survey as a "major" earthquake. In general earthquake over a magnitude of 4 or 5 can cause damage although the exact reasons why some earthquake are more damaging than others is more complext than just the absolute magnitdue of the earthquake. For more information on this, see the related question.
What was the length and damage of Peru earthquake in 1970?
The 7.9 magnitude quake lasted 45 seconds, killed an estimated 80,000 people, and left more than a million homeless.
What happens to earthquake magnitude as the length of the moving fault changes?
As the length of the slipped fault increases (all other factors being equal), so too does the magnitude of the earthquake.
What is quantitative evidence?
Quantitive evidence is evidence that has to do with numbers. For example. the magnitude of an earthquake the time the earthquake occurred and the length of the earthquake are all types of quantitive evidence
What value is used to define an earthquake as small on the moment magnitude scale?
The length of the fault rupture, the relative displacement of the fault and the elastic modulus of the rocks affected, where the smaller these values, the smaller the magnitude of the earthquake. Also the amplitude of seismic waves can be used to estimate the moment magnitude and the smaller the amplitude, the lower the magnitude.
