The problem began on the right side of that picture.

Pier footing, pier or steelwork.

Bank on it.

I don’t say that very often, but pictures don’t lie.

I agree. Based on some of the other pictures I have seen I would speculate that the problem started not over the pier closest to the water but over the much smaller pier set farther back from the water.

Why did both sections land flat with no twisting or turning?

Cantilever or pier/footing failure results in a straight vertical drop?

And couldn't a drought cause shifting in the earth or footings? I still think the heat has something to do with it.
