Morphology

seismometer = seism (semi-transparent) = seism + meter

The word literally means a device for measuring seismic activity, but the specialized combining form 'seism' is not familiar to most learners, so the meaning is only partly transparent.

Etymology

Seismometer comes from the Greek parts seismo- meaning 'earthquake' and -meter meaning 'measure', and you can see -meter in everyday words like thermometer or speedometer. So a seismometer is a tool that 'measures' movements in the ground and helps scientists detect earthquakes.
