The earthquake magnitude is a measure of the amount of seismic energy released by it, so it is a quantitative scale. Magnitude is the most commonly used measure to describe the overall strength or size of an earthquake. The magnitude of an earthquake is expressed in decimal fractions and whole numbers.Therefore, the greater the magnitude, the more energy is released during the earthquake. Following this logic, this would be a logarithmic scale. Put another way, the increase in magnitude of 1 unit would correspond to the increase in energy release of 30 units. And it is based on this theory that the Richter Scale arises.Here are all the Scale used to measure magnitude of earthquakes answers for CodyCross game.
