Fig. 5. Schematic representation of irregular rupture trace showing areas of enhanced (checker pattern) and reduced (diagonal hachures) mean stress arising with the rupturing. The direction of rupture propagation determines whether the fault bend/jog is dilational or compressional. The diagram can either represent a map view of a strike-slip fault or a cross-section through a dip slip fault (redrawn from Sibson, 1994).
