The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale, developed in the 1930s, is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.
As measured with a seismometer, an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times that of an earthquake that registered 4.0, and thus corresponds to a release of energy 31.6 times that released by the lesser earthquake. The Richter scale was succeeded in the 1970s by the moment magnitude scale. This is now the scale used by the United States Geological Survey to estimate magnitudes for all modern large earthquakes.
In 1935, the seismologists Charles Francis Richter and Beno Gutenberg, of the California Institute of Technology, developed the (future) Richter magnitude scale, specifically for measuring earthquakes in a given area of study in California, as recorded and measured with the Wood-Anderson torsion seismograph. Originally, Richter reported mathematical values to the nearest quarter of a unit, but the values later were reported with one decimal place; the local magnitude scale compared the magnitudes of different earthquakes. Richter derived his earthquake-magnitude scale from the apparent magnitude scale used to measure the brightness of stars.

Nepal has been hit by two huge earthquakes, a 7.8 and a 7.3 on the Richter Scale. What are the different ways seismologists measure earthquakes and what do these ratings mean?

The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction."

www.iris.edu/educate for more animations Scientists have developed far-more sensitive seismometers that, with faster computers, have enabled them to record & interpret a broader spectrum of seismic signals than was possible in the 1930's, when the Richter magnitude was developed. The Richter Magnitude Scale is effective for nearby earthquakes below magnitude 7, but not for larger earthquakes. The Moment Magnitude Scale uses seismograms plus what physically occurs during an earthquake (which can also be derived from seismograms), known as the "seismic moment". The seismic moment defines how much force is needed to generate the recorded waves. That information is plugged into the moment magnitude scale to give us the amount of energy that is released during an earthquake. For an interact...
Wanna know more about earthquakes and the Richter scale? Today we talk about how earthquakes occur and how do we measure earthquakes, with an emphasis on the Richter scale. Here you will understand the history of this scale of magnitude and how we determine the magnitude of an earthquake on this logarithmic scale. We also talk about where this information comes from: what are seismic waves and how these waves are detected by seismograph.

The USGS no longer reports earthquake magnitudes on the Richter Scale since it was replaced by the more accurate moment magnitude scale. So let's talk about what it all means.

[Erick Sermon]
Uh-huh
Yeah, aww yeah, uhh ";Richter Scale";
It goes lights, camera, action I'm on
One more time to kill em, my rap flow is fulfilling
I scream with the Beastie Boys -- What time is it?
It's two o'clock, you gettin knocked out the box
then kicked off the block, Def Squad Hit Squad
no we won't stop, fuck it call the cops (uh-huh)
I be the invincible, in the school of hard knocks
I'm the principle, Fatman Joe y'know
[Parrish Smith]
As you suffer the repercussions, comin through the blaze
bust the crime scene, cause some drama, niggaz duckin
When we come through, throwin the jab, in the one-two
Layin MC's out to trap, when we run through (like what?)
Like the marathon, flooded with the diamonds on
Get my rhymin on, PMD fuckin shinin on
Back to Biz, new address with the fat crib
My shit in the Wiz, poli'-in with the big wigs
Chorus: Erick Sermon
Off the meter, and everytime we reach the
tip-top and ya don't stop, uhh!
In the field of rap, we pull rank no question
We top the ";Richter Scale";
*repeat 2X*
[Erick Sermon]
Bust the techniques, E.D. fantastic
Unreal GangStarr shit, Mass Appeal
Rap's top dawg, I'm the one you call on
to get Sic'-Wid-It, E don't forget it
I'm six, two and a half, heavyset, chocolate brown
Hell of a jab, gift to gab
I'm the elite, keep it underground like street level
I rock a Rolex watch, with a diamond bezel
[Parrish Smith]
Rap terror terror, EPMD, a new era
Off the richter scale, blowin hotter than ever
with the Squadron, beg your pardon, got the heads noddin
Lost your mind and said, ";Shit!!"; when we barged in
the front door door, rugged, keeps our shit raw raw
Make hits for the fans, plus the world tour
Believe that, peep that E and P's back
Wreckin heads daily, so chill and Get the Bozack
Chorus
[Erick Sermon]
Yo Royal Flush-in, all my cats be bustin
Servin you Customers and those fake hustlers
Whassup? Step to me, I smack you silly
I'm the Kid, but no comparison to Billy
I ain't scared of you motherfuckers -- can't you tell?
Girls lose to me when they groove to Maxwell, uhh
I got one life to live so I'm livin
Got girls to be hittin more cars to be drivin
[Parrish Smith]
We stripped too many beats to make too many niggaz to break
No moves are fake, no warnin shots fired blastin on crews like corrupt Jakes
The Black Viper, scream on MC's and rhyme cyphers
More Dangerous Mind than, Michelle Pfeiffer
So skedaddle-daddle, you get rattled don't wanna battle-battle
Put one to your rhyme saddle, stompin through, like wild cattle
We flow beef so dead that, let that shit cease
I'm quick with the hands, plus accurate with the two-piece
Chorus
