Settling under Older Concrete Deck

[nrobfd_pl]

Another day, another question about our 20ish year old pool. Recently, I dug down to the skimmer to bond the pool water. In the process, I noticed that the deck on this side of the pool is almost completely supported by the wall brackets and that all the dirt/fill has settled underneath leaving a decent gap:
The deck is in great shape on this side has no signs of settling/cracking.

Cracking has happened toward the end at the corners though:



Is there anything I should do about this now? Or is this just something that happens to all pools as they age and the ground settles?

Could be animals, water washing soil away or settling. It would be wise to get something under there to support it before it actually does crack and sink.
