俯冲边界处的构造板块之间的聚合大部分被调节为沿着俯冲界面逆冲断层的滑动。地震发生的断层部分称为地震带。在发震带，断层被认为在两次地震之间被锁定（由于摩擦），俯冲板块和俯冲板块之间的大部分运动在大型逆冲地震中瞬时发生，其中包括地球上有记录的最大地震。然而，在某些情况下，俯冲逆冲滑动会以稳定的抗震蠕变（没有大地震）的形式发生，并且最近发现，许多俯冲逆冲的部分在缓慢滑动事件（SSE）中会发生偶发性滑动，需要数周至数年才能发生[例如，参见 Schwartz 和 Rokosky，2007]。
Convergence between tectonic plates at subduction boundaries is mostly accommodated as slip along the subduction interface thrust fault. The portion of the fault where earthquakes nucleate is known as the seismogenic zone. In the seismogenic zone the fault is thought to be locked (due to friction) during the time between earthquakes, and most of the motion between the subducting and overriding plates occurs instantaneously in major megathrust earthquakes, which include the largest earthquakes recorded on the planet. However, in some cases subduction thrust slip occurs as steady aseismic creep (without a major earthquake), and it has been recently discovered that portions of many subduction thrusts slip episodically in slow slip events (SSEs) that take weeks to years to occur [see, e.g., Schwartz and Rokosky, 2007].
