'this might explain it' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'my soil goes shaky?' is the wordplay.
'shaky?' indicates an anagram (I've seen 'shaky' mean this).
'my'+'soil'+'goes'='mysoilgoes'
'mysoilgoes' with letters rearranged gives 'SEISMOLOGY'.
