I was thinking some kinda wild freeze / thaw / freeze
On closer examination looks like door 1 held the water back until it burst and then either the force of water blew door 2 open or door 2 held until it burst later.
Even if true, there's not equal support around the door.
The bottom of the door isn't braced on the bottom, but the top and edges are.
The left side is supported on multiple hinges that are solid, and keep the edge a fixed distance from the frame. The right and top edges are supported by relatively thin metal that only provide bracing in one direction.
the door bowed from the pressure and the bottom right corner fails first.
once the corner was out there's more leverage for twisting the door.
the top right corner is stuck, diagonal crease appears as the door tries to "twist", this wedges the corner more into the frame.
Honey, the door is locked shut. We'll need to call the superintendent to come help us out, so I don't think you're going to reach that Taylor Swift concert.
