where plate boundaries occur within the continental lithosphere, deformation is spread out over a much larger area than the plate boundary itself. in the case of the san andreas fault continental transform, many earthquakes occur away from the plate boundary and are related to strains developed within the broader zone of deformation caused by major irregularities in the fault trace (e.g., the "big bend" region). the northridge earthquake was associated with movement on a blind thrust within such a zone. another example is the strongly oblique convergent plate boundary between the arabian and eurasian plates where it runs through the northwestern part of the zagros mountains. the deformation associated with this plate boundary is partitioned into nearly pure thrust sense movements perpendicular to the boundary over a wide zone to the southwest and nearly pure strike-slip motion along the main recent fault close to the actual plate boundary itself. this is demonstrated by earthquake focal mechanisms.
