There are 2 ways.
seismometers and magnitude
Lilly, who is a scientist, used a seismograph to determine the strength of the earthquake that had just hit Haiti.
the strength of an earthquake.
The simplified answer is that it works much in the same way you would determine the source of a sound (which is also in waves). Multiple measurements of the intensity are taken from different locations are used to triangulate an earthquake.
The Ritcher Scale is used to measure earthquake strength.
Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)

The Seismograph is used to measure the Magnitude of an earthquake.
You use a seismograph to measure the strength of an earthquake.
The scale used to measure the strength of an earthquake is called the Richter scale
Depends on it's magnitude which can range. Seisometers are used to measure the Magnitude of an earthquake. Magnitude is it's strength.
The Richter magnitude scale is used to measure the strength of an earthquake.
richter scale
the strength of an earthquake.
A device used to measure the strength of an earthquake
The Richter scale is used to measure the strength of earthquakes.
Seismic waves can be used to determine the location of an earthquake focus. These waves are triggered by tectonic plates.
