Using seismic moment (M0)–length (L) data for stable continental region (SCR) faults, augmented by data not included in previous studies, this article reassesses and confirms the bilinear scaling relation for the dip‐slip faults of Leonard (2010). Furthermore, using the new data, I propose a separate bilinear relation for estimating magnitude from surface rupture length. There are now a small number of SCR strike‐slip earthquakes for which the fault dimensions have been estimated. I use these to constrain a trilinear scaling relation for this class of fault.
For the four fault types (interplate dip slip, interplate strike slip, SCR/intraplate dip slip, and SCR/intraplate strike slip), the scaling relations for the 10 permutations of M0, D, L, W, and A are given.
