The avalue depends on the area and time-window of investigation and describes the productivity, while the slope bdescribes the relative size distribution of earthquakes. WebA systematic study of b-values in New Zealand has shown that within the vicinity of forthcoming large earthquakes there is initially an increase in b and then a return to …
The parameter b (commonly referred to as the "b-value") is commonly close to 1.0 in seismically active regions. This means that for a given frequency of magnitude 4.0 or larger events there will be 10 times as many magnitude 3.0 or larger quakes and 100 times as many magnitude 2.0 or larger quakes. See more In seismology, the Gutenberg–Richter law (GR law) expresses the relationship between the magnitude and total number of earthquakes in any given region and time period of at least that magnitude.
