The Mercalli scale, which measures the visible effects; and the Richter scale, which measures the energy given off by the earthquake, are the two most common ways of measuring the size of an earthquake.
different scals
because the Richter scale is outdated and the moment magnitude scale is much more accurate
The Richter and moment magnitude scales (depending on the Earthquakes size).
There are actually 3. But 2 of them are The Mercalli scale measures an earthquake's intensity which is the strength of the ground motion in a given place. It is not very accurate though. The Richter scale measures the size of seismic waves. It gives it a rating from 1 which is the lowest(can't be felt) to 9(deathly destruction) These 2 scales are very similiar.

The Richter scale, which measures the magnitude of earthquakes, was developed by Charles Richter in 1935.
TheRichter Scale created by Charles Richter and the Mercalli Scale created by Giuseppe Mercalli.
Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)

The instrument that is used to measure the magnitude of an earthquake is a seismometer.
The Richter scale is used to measure the strength of earthquakes. The scale is exponential - in that force 2 is ten times that of force 1. It ranged from force 0 to force 10.
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.
