All magnitude scales hold the logarithmic person of the first and are scaled to have generally tantamount numeric qualities.
Preceding the advancement of the magnitude scale, the main proportion of a quake's solidarity or "size" was an emotional evaluation of the force of shaking saw close to the focal point of the tremor, classified by different seismic power scales, for example, the Rossi-Forel scale.
