Island trauma's resolved (7)

I believe the answer is:

sumatra

'island' is the definition.
(I know that Sumatra is a island)

'trauma's resolved' is the wordplay.
'resolved' indicates an anagram.
'traumas' anagrammed gives 'SUMATRA'.

(Other definitions for sumatra that I've seen before include "Eastern island" , "part of Indonesia" , "island in Indian ocean" , "Island in western Indonesia" , "Second largest Indonesian island" .)

I've seen this clue in The Daily Express.
