magnitude

Magnitude increasing by 1 means 32-times more energy!

Symbol: M / Base data: Earthquake.
The maximum amplitude recorded by a seismograph located 100 km away from the epicenter is measured in micrometers and the common logarithm of that figures is taken

Expresses the size of the energy in the seismic center

Seismic intensity is the size of tremors measured in various regions, but the magnitude is the size of the energy in the seismic center. There is a vast amount of energy, but it is expressed as a logarithm to shorten the number of digits. When magnitude increases by 1, this means that energy increases by 32-times. If magnitude increases by 2, this means 1000-times more energy.
