Nice Peter sacked where disaster strikes (9)
I believe the answer is:
epicentre
'where disaster strikes' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'nice peter sacked' is the wordplay.
'sacked' indicates an anagram.
'nice'+'peter'='nicepeter'
'nicepeter' with letters rearranged gives 'EPICENTRE'.
Can you help me to learn more?
(Other definitions for epicentre that I've seen before include "where maximum damage may occur" , "focal point" , "a very disturbed place" , "Shocking scene" , "Area most affected" .)
