2/ Because they are not planar vertical boundaries. Earthquackes occur preferentially in zones where local compression exists along a bent for instance.

3/ A tectonic regime that combines strike-slip and convergent plate motions.

4/ A tectonic regime that combines strike-slip with divergent plate motions.

5/ Strain is partitioned when the characteristics of strain vary significantly from one domain to the next.

6/ Strike-slip faults, reverse faults, folds, positive flowers.

7/ Strike-slip faults, normal faults, negative flowers, pull-apart basins.

8/ Basins that form because of a bent along major strike-slip faults such as transcurrent plate boundaries.
