Reportedly fracture part of foot next to American volcano (8)
I believe the answer is:
krakatoa
'volcano' is the definition.
(I have seen 'Indonesian volcano' mean 'krakatoa' so perhaps 'volcano' could also mean 'krakatoa')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for krakatoa that I've seen before include "Site of significant eruption in 1883" , "Indonesian volcano" , "Indonesian volcanic island with a massive eruption in 1883" , "Indonesian caldera" , "major disaster, naturally" .)
