The following formula has been found useful for calculating the GUTENBERG-RICHTER'S magnitude of an earthquake occurring in or near Japan from seismometrical data obtained at Japanese stations:M=1.73logΔ+logA-0.83, where A is the maximum displacement amplitude of the ground due to that earthquake (measured in micron) observed at an epicentral distance Δ (measured in km) and log is the common logarithm.
