Morphology

aftershock = shock (transparent) = after + shock

The sense is a straightforward combination of 'after' + 'shock' meaning a tremor that follows the main shock. [Postprocessing: moved 'after' from base_words to prefix]

Etymology

The word aftershock comes from the parts after- meaning 'later' and shock meaning 'a sudden jolt or movement', like a smaller jolt that follows the first big one. So an aftershock is a smaller earthquake or shaking that happens after the main quake.
