Of earthquakes (7)

Ross

I believe the answer is:

seismic

'of earthquakes' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for seismic that I've seen before include "Caused by an earthquake" , "shock" , "Resulting from earthquakes" , "Earthshaking" , "of enormous proportions" .)

I've seen this clue in The Telegraph, the L.A. Times Sunday, The Sun and The Mirror.
