What is the hole in the tube like? Or is it too late?
Large hole, ragged edges (blowout)?
Two small holes (pinch flat)?
It still might be difficult to tell exactly how it occurred, but that might give some indication of what happened.
I recently hit a deep crack in the pavement. I ended up with a pinch flat, a sidewall puncture, two scrapes on the sidewall, and it let the air out rapidly (within a few feet of the impact). But no blowout. I don't think I've ever had a blowout from a pinch flat.

This is from both my engineering training and curiosity and the fact that I rode a bike years ago, didn't do this analysis and suffered life altering consequences. That was in my twenties. Since then I have known that any bike I genuinely loved was likely going to be ridden to failure. (5 so far.)
For that reason I will never own carbon fiber forks. They will be brazed steel with scalloped (old fashioned) crowns. (I could go on about a steel fork that didn't have that feature but won't. Scary.) CF frames share the same failure characteristics that the OP saw here. Brittle failure. (See my post above.)

Note, none of the carbon parts (fork or seatstays) appear to have any visible damage in this accident.
All the damage is isolated to the aluminum parts and welds.
