Why do rocket impacts often look like bang snaps?

Question

I often ask myself why impacts from rockets, missiles or grenades often look like a small explosion without a lot of destruction the moment they hit something , like seen here:

And in the end the aftermaths of something like that are waaay bigger and more severe than seen in the second of the impact. Does it have to do because buildings collaps some time after being hit by a weapon?

If I see videos of explosions I think: Ok wow, luckily the explosion wasn’t that big so nothing bad must happened.
And then later when seeing the aftermath in the news I’m like: FUCK, how did the building completely vanish?

Much of the destructive effect doesnt come from the big fireball you’re expecting, but from the air/gas expanding from the point of impact, which isnt always as visible.
