What else can I help you with?
Are the Richter scale and the beaufort scale the same thing?
No, the Richter scale is used to measure the magnitude of earthquakes, while the Beaufort scale is used to estimate wind speeds based on observable effects on land and sea. They are different scales used for different purposes.
What is a measurement to an earthquake?
There are two instruments, which are basically the same thing. There is the seismograph , and a more specific tool measures the waves on what is called the Richter scale. Earthquakes are given a number from one to ten, ten being the strongest. The strongest earthquake that their ever was, was measured a 9.3.
What scale is used to measure the energy released by an earthquake?
The moment magnitude scale is used by seismologists to measure the amount of energy released by large earthquakes (those greater than magnitude 8.0). For smaller earthquakes (those with magnitudes less than 7.0 and with epicentres less than 650 km from a seismometer station may be used) the method devised by Richter (the Richter magnitude scale) may be used to estimate the magnitude. The surface wave magnitude scale may be used for earthquakes with magnitudes up to 8.0 (devised by Richter and Gutenberg to extend the utility of the Richter scale.) Richter magnitudes are generally easier to derive than moment magnitudes being based on direct seismometer measurements, whereas the moment magnitude is a more4 fundamental measurement of magnitude being based on the rock mass strength around the fault, the amplitude of fault movement and the cross sectional area of that portion of the fault that moved. However this is more difficult to measure. As such it is common for initial reports to be in Richter magnitudes and more detailed letter magnitudes to be reported as moment magnitudes.

What describes how much energy an earthquake releases?
A magnitude 5.0 earthquake releases the energy of about 200 tons of TNT. Because of the logarithmic increase, a 7.0 quake releases the equivalent of almost 200,000 tons of TNT which is 10 times the strength of the atomic bomb dropped on Hiroshima.
What is the difference between the Richter scale with the moment of magnitude scale?
well nothing. they are the same
Is there a scale for the severity of the tsunami?
The scale for a Tsunami is a Richter Scale. The Richter Scale is a scale that measures earthquakes, and Tsunamis are normally made by earthquakes. But be careful, because Tsunamis are normally formed by 6.5's or greater on the Richter Scale. -I hope I helped Actually, the Richter Scale is invalid, and we do not use it any more. The scale we use today is the MMS, or Moment Magnitude Scale. In the MMS, every point up the scale (Which goes from 1-10), multiplies it's magnitude by 30.
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.

Is a 6 0n the Richter scale double the force of a 5 on same scale?
No, each point on the Richter scale represents a tenfold increase in amplitude and approximately 31.6 times more energy release. Therefore, a magnitude 6 earthquake has about 10 times more ground shaking and releases about 31.6 times more energy compared to a magnitude 5 earthquake.
Is a seismograph the same thing as the Richter scale?
No!

What scale is described for damage in an earthquake?
Technically, you can't tell damage from the Richter Scale, because the Richter Scale rating of an earthquake stays the same no mater how far out you go from the epicenter. The scale that measures the damage of an earthquake (meaning the scale rating gets lower the further you go from the epicenter) is called the Mercalli Scale. The Mercalli Scale goes from II to XII (2 to 12) and the rating on the Mercalli Scale in which damage starts to occur is about 6. However, if you are going by the Richter Scale, damage at the epicenter would start at about 5.0
