That pool looks like it may be a DOUGHBOY brand pool. They are one of the leading companies in the above ground pool business.

Doughboy Pools

We had one at our first house years ago the same size (24ft. round). We were advised to drain the pool down below the skimmer in freezing weather but we never had that worry at the time.

I've never seen one collapse as that pictured. It may be possible that the pool was allowed to be over filled with water which the water pressure could have led to the wall collapsing.

I'd contact the above company DOUGHBOY and maybe ask them about such an issue.

Good Luck.
