If faults opened up, no earthquake would occur because there would be no friction to lock them together.

如果断层裂开，也不会发生地震，因为没有摩擦力把它们合到一起。

Movement occurs along the plane of a fault, not perpendicular to it. If faults opened up, no earthquake would occur because there would be no friction to lock them together.

即使断层裂开，也不会发生地震，因为那样的话，就不再有摩擦力了（摩擦力会使相接触的断层应力不断积累而最终诱发地震）。
