<P> A deep - focus earthquake in seismology ( also called a plutonic earthquake ) is an earthquake with a hypocenter depth exceeding 300 km . They occur almost exclusively at oceanic - continental convergent boundaries in association with subducted oceanic lithosphere . They occur along a dipping tabular zone beneath the subduction zone known as the Wadati -- Benioff zone . </P>
