How many times greater is the maximum ground motion of a magnitude 4 earthquake compared with that of a magnitude 2 earthquake?
Not sure, but if i remember my Richter scale correctly it's logarithmic. if it's base 10 logarithm then a magnification difference from 2 to 4 would mean 10^2 * 10 = 1000 times greater.
A magnitude 6 earthquake is how many times greater than a magnitude 5 earthquake?
1000 times as much
How is magnitude using the Richter scale?
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).
How long did the San Fernando earthquake last?

What is the energy level difference between a magnitude 5 earthquake and magnitude 6 earthquake?
A magnitude 6 earthquake emits roughly 31 times more energy than a magnitude 5 earthquake. The magnitude 6 quake will also have a maximum seismic wave amplitude of ten times the magnitude 5 earthquake.
What was the maximum intensity of the 1960 Chili earthquake?
9.5 on the moment magnitude scale.
Which city is in greater danger of being hit with a 9.0 magnitude earthquake San Francisco or Seattle?
Seattle is located very close to the Cascadia subduction zone, where earthquakes of magnitude 9.0 have occurred in the past. The San Andreas fault which bypasses San Francisco, is not capable of such an earthquake due to it being a transform fault, where the maximum magnitude would be about 7.8-8.0.
A magnitude 6 earthquake is how many times greater than a magnitude 5 earthquake?
1000 times as much
How is magnitude measure using Richter scale?
The Richter scale assigns a magnitude number to an earthquake based on the maximum amplitude of the seismic waves as recorded on a seismometer and the distance of the seismometer station from the epicentre of the earthquake.
How is an earthquakes magnitude measured using the Richter scale?
The Richter scale assigns a magnitude number to an earthquake based on the maximum amplitude of the seismic waves as recorded on a seismometer and the distance of the seismometer station from the epicentre of the earthquake.

Does the earthquake magnitude system have a maximum value of 9?
No it is based on a scale of 1 to 10 and the only way a 10.0 earthquake could happen would be all of the faults join together to form one big earthquake.
What does a Richter scale measure on an earthquake?
RICHTER SCALEThe Richter scale (known as the local magnitude scale to seismologists) was originally developed to measure small to moderate magnitude earthquakes in southern California by Charles Richter and Beno Gutenberg. The numerical levels indicate the energy released by a particular quake. The numerical value is obtained from the logarithm of the maximum amplitude of seismic waves as recorded on a seismometer. This value is then scaled to account for the distance from the epicentre of the earthquake to the seismometer so as to allow the value to be correlated with the local magnitude readings from other seismometers in differing locations (as seismic waves lose their energy as they propagate through the earth so if this correction was not made, then different seismometer stations at different distances would give differing Richter magnitudes for the same earthquake). The Richter magnitude measurement produced by this methodology in theory has no limit and may be positive or negative.As stated above, the Richter scale itself is a logarithmic mathematical formula which is calibrated so that a ten fold increase in amplitude relates to a single whole number increase on the scale (e.g. an earthquake with a Richter magnitude of 5 has seismic waves with a maximum amplitude 10 times larger than those for a magnitude 4). It has a number of practical limitations, in that it is poor at recording earthquakes with magnitudes greater than 7 and at distances greater than 650 km from a seismometer.The equation for calculating the Richter magnitude (MR) is shown below:MR = (Log10A) - (Log10A0)WhereA = maximum zero to peak amplitude of seismic wave (mm) recorded.A0 = Empirical function derived from the distance from seismometer station to earthquake epicentreLog10A0 From 0 to 200 km distance:Log10A0 = 0.15 - 1.6 log(distance in km)Between 200 and 600 km distance by:Log10A0 = 3.38 - 3.0 log(distance in km)Due to the limitations described above (distance and maximum size of measurable earthquake), it has since been replaced by the Moment Magnitude Scale in the measurement of large earthquakes - for information on this, please see the related question.the richter scale reads the magnitude of earthquake.
What is magnitude earthquake?
The "moment" magnitude of an earthquake is a measure of how much energy is released when an earthquake occurs. It is derived from the stiffness or rigidity of the rock mass around the fault rupture zone, the length of the fault that moved and the cross sectional area of the fault zone. Seismologists can also estimate its value based on the amplitude of seismic waves recorded on a seismometer. The Richter scale (currently used to measure small and medium strength earthquakes with magnitudes below 7.0 - larger earthquakes magnitudes are measured using the moment magnitude scale as described above) is also a measure of the amount of energy released by an earthquake and is derived based on the maximum amplitude of the seismic waves as recorded on seismometers.
