abstract

On performing a statistical analysis of the data available from both the National Geophysical and Solar Terrestrial Data Center (NGSDC) and other, smaller data bases, a convincing shape regularity was observed in the derived earthquake frequency-magnitude (f-M) distributions. The f-M distributions were obtained from sets of events originating within widely separated regions on the Earth. The regions have geological diversity and areas greater than 6 × 105 km2. To within estimated error, the shape of total world data agrees with similar plots of data subsets taken from these eight separate regions of the Earth.
