parquet flooring damage

[Oz07]

Anyone like to have a guess why the below parquet floor was damaged. I thought possibly water damage with the associated radiator pipework being close by. Am I missing anything or does this sound likely?

I’m going to go out on a limb and say 

subsidence 

looks like solid floor has dropped causing a crack in that location. 

.????????????

pocket cut out in border and heating pipe drop in that location also makes me think leak and dried out. No obvious cracks in walls to suggest subsidense.

Have you lifted any to see how they are stuck down

the original ones will probably be stuck down with a type of bitumen 

see what the moved ones are down with.

Not yet no. Will it help as in because you will see any subfloor crack?
