'seismic shock' is the definition.
'tremor' can be an answer for 'shock' (I have seen 'Small shock ' mean 'tremor' so perhaps 'shock' could also mean 'tremor'). I'm not sure about the 'seismic' bit.

'turkey's capital city recalled' is the wordplay.
'turkey' becomes 'tr' (I've seen this in other clues).
'capital city' becomes 'rome' (I've seen this before).
'recalled' is a reversal indicator.
'rome' reversed gives 'emor'.
'tr'+'emor'='TREMOR'

(Other definitions for tremor that I've seen before include "Quiver or vibration" , "Vibration - shaking" , "make one shake" , "Nervousness" , "Minor quake" .)
