Recorder of earth movement that’s wrecked gophers’ aims (11)
I believe the answer is:
seismograph
'recorder of earth movement' is the definition.
(a seismograph records earth tremors)
'wrecked gophers' aims' is the wordplay.
'wrecked' is an anagram indicator.
'gophers'+'aims'='gophersaims'
'gophersaims' is an anagram of 'SEISMOGRAPH'.
'that's' acts as a link.
(Other definitions for seismograph that I've seen before include "Instrument for registering earthquakes" , "Earthquake recorder" , "Earthquake measuring instrument" , "Earthquake detector" , "Tremor detector" .)
