Disaster, calamity (11)

I believe the answer is:

catastrophe

I believe this clue is a double definition.

'disaster' is the first definition.
(synonyms)

'calamity' is the second definition.
(synonyms)

(Other definitions for catastrophe that I've seen before include "Event causing much damage" , "Sudden disaster" , "Terrible event" , "Event causing great damage" , "Event causing great suffering" .)

I've seen this clue in The Telegraph.
