WHY DID MY SERPENTINE BELT COME LOOSE?

Was driving and the power steering got real hard and van started overheating. I pulled over before it got all the way in the red. Twice but made it home. There wasnt any smoke or anything but when I lifted the hood I saw my (new) serpentine belt just hanging there. It is not torn, cracked or has any abrasions. What could have caused this?

Update: The mechanic put my belt back on and couldnt give me a reason why! I mentioned the tensioner
And he said it could be. Sad face. So I am hoping its just. Everything seems fine for now. Thank you!
