1.
aftershock; secondary tremor
A secondary earthquake tremor that follows the main quake, swinging the ground back.
2.
rebound; backlash; swing back; reaction
A return swing or counter-reaction following a major change or trend. Used figuratively for social, political, or economic reversals.
Literally "swing back" from 揺る (to shake) + 戻す (to return). The physical image of a pendulum swinging back underlies both the seismological and figurative meanings.
