Richter Scale
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.
Earthquake
The Richter scale is measures earthquakes unusually. A 1 on the Richter scale is 101 or 10 times the movement of the earth normally but a 2 is 102 or 100 and so on up until a 10 which is a 1010 or 10,000,000,000 times the movement of the earth normally.
The Moment magnitude scale (used for earthquakes larger than magnitude 7) and Richter scales can both be used to measure earthquake magnitude (the energy released) although seismologists now predominately use the moment magnitude scale.Earthquake intensity is measured using the Modified Mercalli Scale or the European Macroseismic Intensity Scale (essentially a tweaked version of the Moddified Mercalli Scale).The Moment Magnitude Scale is used by seismologists to rate the energy released by earthquakes, replacing the now outdated Richter or Local Magnitude Scale (still commonly used in the media).Earthquake severity is measured using the Modified Mercalli Intensity Scale.Please see the related question.
Most people I know like to use the Richter scale.
My rebuilt engine is about 7.5 on the Richter scale! Yesterday's earthquake read 3.2 on the Richter scale. The Richter scale was developed in the 1930s.

The most commonly referred to scale by the press and the public is the Richter scale for measuring earthquake magnitude. However this was actually replaced in the 1970s by the Moment Magnitude scale which is the magnitude scale favoured and in use by seismologists.
They use the Richter Scale.
Earthquake
The local or Richter magnitude scale is named after Charles Francis Richter an American seismologist and geophysicist. Some people use the title Richter-Gutenberg scale to acknowledge the contribution to the scale of Charles Richter's colleague, Beno Gutenberg a fellow geophysicist at the California Institute of Technology. it is worth noting however that geophysicists / seismologists use the moment magnitude scale in place of the Richter magnitude scale when possible as it is more reliable for large magnitude earthquakes (greater than 6.9) and for earthquakes that occur a long distance away from the nearest seismometer station (greater than 600 km).
No. The Richter scale (since replaced by the Moment Magnitude scale) was used to measure earthquake intensity. The Fujita scale (now the Enhanced Fujita scale in the U.S.) is used to rate tornadoes.
