The physical instrument used to measure ground movement is called a seismograph.
seismograph
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
Those devices are called Seismometer's. They are used to measure seismic shockwaves ( earthquake's)
The rector scale.
You use a seismograph to measure the strength of an earthquake.
The Seismograph is used to measure the Magnitude of an earthquake.
The instruments are seismographs or seismometers.
The instrument that is used to measure the magnitude of an earthquake is a seismometer.
The Richter magnitude scale is used to measure the strength of an earthquake.
Richter Magnitude
Depends on it's magnitude which can range. Seisometers are used to measure the Magnitude of an earthquake. Magnitude is it's strength.
Richter or local magnitude scaleMoment magnitude scaleBonus:Surface magnitude scale
Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)

It is a device called a seismographe. It is used to determine the magnitude on a scale which is then deciding how bad the earthquake is.
