B value in seismology
WebThe bvalue estimated by fitting a set of observed earthquake magnitudes to the magnitude-frequency relationship, log N(m) = a- bm, where N(m) = number of earthquakes exceeding magnitude m, is correlated with the fitting technique used. Web7 Nov 2024 · "...the emergence of high and low b value anomalies is a mere artifact of under sampling. These artifacts lead to differences of up to 2 orders of magnitude in the recurrence times; thus, it would be precarious to use such maps for assessment of probabilistic seismic hazard on faults.
