Morphology

seismic = seism (transparent) = seism + ic

The adjective is a regular formation from 'seism' (earthquake) + '-ic' meaning 'relating to', so knowing 'seism' yields the meaning.

Etymology

The word seismic comes from the Greek root seismos, which means 'earthquake' or 'to shake'. So seismic describes things about earthquakes or anything that gives a strong 'shake', which is why we also call a very large change a 'seismic' event.
