'site of famous volcanic eruption' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'is on train touring' is the wordplay.
'touring' indicates an anagram (letters move or tour around).
'is'+'on'+'train'='isontrain'
'isontrain' anagrammed gives 'SANTORINI'.
