Our results are compared with existing scaling relations for subduction environments. The relationships for the rupture area of our results are closer to those of Somerville et al. (2002) than to any other, but, like the others, they have smaller areas than predicted by Somerville et al. (2002). Concerning the combined area of asperities, Murotani et al. (2008) and our results predict smaller areas than those obtained by Somerville et al. (2002). Concerning the area of largest asperity, the relationships obtained in this study are slightly smaller than those described by Somerville et al. (2002); this is a consistent result with the relationships of total rupture area and combined area of asperities. In general, the error estimates for the constrained equations derived in this study in all cases are smaller than those relationships compared here. This might suggest that the expressions obtained in this study could be appropriate for the simulations of strong ground motion for a specific scenario of earthquake slip in the region. Also, these results could be an indication that the relationships vary depending on a specific subduction tectonic region. On the other hand, Aguirre and Irikura (2007) estimated the source area for 31 Mexican earthquakes using corner frequencies; these areas show close resemblance with those predicted by the relationships derived in this study. Based on these findings, an important implication is that two different methodologies to determine the total area of asperities based on either low‐ or high‐frequency data generate similar results.Online Material: Figures of fault models.
