Please someone else wrtite a answer down! i need it for homework.
The moment magnitude uses seismographs plus what physically occurs during an earthquake.

to measure the amount of energy released during an earthquake
The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
A seismometer is an instrument used to measure and record ground movements during an earthquake. It detects the vibrations caused by seismic waves and produces a graphical representation called a seismogram.
During an earthquake, seismic waves are released. These waves travel through the Earth and can be detected by seismographs. The main types of seismic waves are P-waves (primary waves), S-waves (secondary waves), and surface waves.
Earthquake magnitude is a measure of the energy released during an earthquake. It is typically measured using the Richter scale or the moment magnitude scale. These scales assign a numerical value to quantify the seismic energy released, with each whole number increase representing a tenfold increase in amplitude.
Earthquake waves are called seismic waves.
If you are referring to the record printed on a chart by a seismograph, it is called a seismogram. If you are referring to a hand-written record of the events of an earthquake, this might be referred to as a journal.
Scientists measure earthquake magnitude using seismometers, which detect and record ground motion. The most common scale used to measure earthquake magnitude is the Richter scale, which is based on the amplitude of seismic waves. More recently, the moment magnitude scale has become the preferred method for measuring earthquake magnitude as it provides a more accurate representation of the energy released during an earthquake.
