Calm stay disrupted around college? A disaster (9)
I believe the answer is:
cataclysm
'a disaster' is the definition.
('cataclysm' can be a synonym of 'disaster')
'calm stay disrupted around college?' is the wordplay.
'disrupted' indicates an anagram.
'around' indicates putting letters inside.
'college?' becomes 'c'.
'calm'+'stay'='calmstay'
'calmstay' anagrammed gives 'catalysm'.
'catalysm' enclosing 'c' is 'CATACLYSM'.
(Other definitions for cataclysm that I've seen before include "A violent upheaval or disaster" , "Violent event" , "Disastrous upheaval or flood" , "Deluge: upheaval" , "Debacle" .)
