Mignan et al. (2015) estimated the maximum rupture lengths for strike-slip faults, by applying a multisegment rupture method, and calculated new Mmax values, by applying selected strike-slip scaling relations. In an initial step they compared the European fault length - Mmax data with five candidate relations and on the basis of this comparison dismissed two. In this paper the bilinear scaling relation of Leonard (2010, 2014) was incorrectly applied and so gave anomalously high estimates of magnitudes for fault lengths greater than 45km. As such it was excluded from future consideration. The problem likely arose due to the MW relations in Table 6 of Leonard (2010) being a subset of the full set of M0 relations given in Table 5. A more comprehensive set of MW relations is given in Leonard (2014). Table 1 below is the equivalent of Table 1 in Mignan et al. (2015), with all the relations reworked into the MW = a + b log(L) formulation to allow easier comparison.
