What's the crater in the mountain shown after Izuku talks to Kota in season 3 episode 3?


In My Hero Academia last episode, after Izuku talks to Kota, they show a sort
of crater in the mountain. Does the manga say anything or help to guess what
this could be? Does this have any relation with Kota?
