Using a point source model of the earthquake source, they find that the tangential (transverse) component of horizontal ground motion with reference to the epicenter, rather than the strike‐normal component, is dominant for strike‐slip earthquakes at distances larger than some value, variously given as 3, 5, 20, or 30 km. The authors note on page 10 that “Establishing the limiting distances and transition between these two preferential orientations (i.e., strike‐normal and transverse)...
