This can be difficult to answer, especially in cases of heterogeneous rock
types and the resultant mechanical stratigraphy effect. I published a
study on this back in 1999, comparing numerical predictions of normal
fault propagation direction with actual observations of fault dimensions
in 3D. Although I found that faults mechanically want to propagate upwards
to become taller than they are wide (long), in actuality, many faults are
longer than they are tall (deep) because they are guided more by
mechanical layering, as well as lateral linkages between layer-bound
segments. I didn¹t do any analyses of length/depth scaling though.
