Morphology

seismicity = seismic (transparent) = seismic + ity

Formed from the adjective 'seismic' with the nominalizing suffix '-ity' to mean 'the state or frequency of seismic events', a direct and regular derivation.

Etymology

Seismicity comes from the Greek root seismos meaning 'shake' and the ending -ity meaning 'state', and you can see the same root in seismic. So seismicity is the 'state of shaking', meaning how often and how strong earthquakes happen in an area.
