Fig. 2: Relationship between absolute plate motion directions and maximum horizontal stress (SHmax) orientations in central and eastern North America.
From: Multiscale variations of the crustal stress field throughout North America
a Stress map subset with profiles parallel to absolute plate motion. b Angle α, the mean divergence between SHmax orientations and plate motion, was sampled every 0.1° along 4°-wide swath profiles from a slightly smoothed grid of divergence angles. The shaded regions represent the full range of divergence angles sampled across each swath profile. Divergence angles were estimated by subtracting interpolated A and B quality SHmax orientations from NNR-MORVEL5630 plate motions.
