= Solution
The network partitions deformation into oblique horizontal displacement on the <strike-slip fault> and more directly north–south <crustal shortening> on the approximately east–west <reverse fault>. On the oblique strand, northeastward motion of the southeastern side relative to the northwestern side has a northward component, reducing separation in the direction of $\sigma_1$. On the <reverse fault>, northward and upward motion of the southern <hanging wall> shortens and thickens the crust.
Sketch north–south opposing compression arrows around the plan view, left-lateral arrows along the oblique trace, and teeth on the southern side of the <reverse fault> trace. A section normal to the latter shows horizontal shortening converted into <tectonic uplift>. Where strands meet, <folding>, distributed <strain> or subsidiary <faulting> can maintain displacement compatibility; a <strike-slip fault> terminating abruptly in undeforming rock would not. This is an interpretation involving <transpression>, and the map does not by itself give a unique partition of slip rates between the strands.
