What measure you should take for earthquake?
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
What magnitude was the March 28 earthquake?
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).
How many earthquakes do we detect each year and how many cause damage?
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.
Why is the intensity value of an earthquake more meaningful than magnitude to a non scientist?
The magnitude measures the total energy release. The intensity measures the... well, the instantaneous "shock" felt by an observer.
Are japan earthquake rating scales different than earthquake rating scales in Oregon?
No, the two standard scales used worldwide are the Richter and the Mercalli:Richter measures total energy release by the quake and is a single valueMercalli measures how the quake felt and the damage it caused at various sites, this gives high values near the epicenter and lower values further awayTo help distinguish them Richter magnitudes are given as a decimal number while Mercalli magnitudes are given in Roman Numerals.
How many more times energy does an earthquake with a Richter magnitude 8 release than an earthquake with a Richter magnitude of 6?
about a 1000
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).
What scale is the instrument that is used to record primary secondary and surface waves of an earthquake?
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.

How much less energy does a magnitude 4 earthquake have than a magnitude 7?
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.
How many times more powerful is an earthquake measuring 7.0 than one measuring 5.0?
The Richter magniude scale is logorithmic. As such the size (amplitude) of the largest seismic waves produced by a magnitude 7 earthquake are 102 (or 100) times larger than those produced by a magnitude 5 earthquake. However the amount of energy released by a magnitude7 earthquake is 1000 times greater (102)^3/2 than a magnitude 5 earthquake and so it is likely to be much more destructive.
What does the Richter scale tell you about an earthquake?
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.
How much more energy does a Richter magnitude 6 release compared to a magnitude 3?
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.
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.

What is the severity scale for earthquakes?
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.
What is the damage a magnitude 8 earthquake can cause?
A magnitude 8 earthquake can release as much energy as 6 million tns of TNT. It can cause severe damage to structures and can very fatal.
