Rumbling from volcano is extreme (5)

I believe the answer is:

noise

'rumbling' is the definition.
(thesaurus)

'from volcano is extreme' is the wordplay.
'from' indicates the answer is hidden within the clue.
'NOISE' can be found hidden inside 'volcano is extreme'.

(Other definitions for noise that I've seen before include "Hum" , "Public talk" , "Clatter" , "Sound - gossip" , "Row" .)

I've seen this clue in The Sun.
