What does 炸裂 mean here?


> 最終ラウンドでチャンピオンのパンチが炸裂した. The champion's punch exploded in the final round.

Did the punch hit really hard? Did it fail? Please explain what 炸裂 means in
the Japanese sentence above, I'm not sure what "the punch exploded" means in
English even and google isn't helping either.




It hit really hard. I don't know if I can call it an idiomatic phrase, but
punches, kicks, and so on can 炸裂 in Japanese.

The typical image of 炸裂 is shown in this video:

This is only my speculation so I am not sure it should be written as "My
Answer," but...

I guess the writer of the said sentence wanted to convey the meaning "the
punch was so hard that it looked exploded." Of course I may be wrong.
