“…This behavior translates into an approximate range of 1 < b < 3.5 in the Gutenberg‐Richter distribution, which is consistent with the b ‐values measured from the fluid‐induced seismic activity (Karimi & Davidsen,
2021,
2023; Kwiatek et al.,
2015; Salvage & Eaton,
2021; van der Elst et al.,
2016) suggesting that the heterogeneity in the yielding thresholds is responsible for the changes in the b ‐value. Furthermore, considering the Newberry EGS catalog from 2012 (Cladouhos et al.,
2013) as a specific example of an isolated injection site away from any known large fault system, its b ‐value of 1.1 translates to λ = 1.75 in our model (see Section 3.1), which is obtained for s max = 1.9 (Figure 1b). The dimensionless ratio of the yielding thresholds in this case,
, is ∼0.40.…”
