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?

Answer 1

Those are small mortars at a distance or something. Also a lot of ordnance is armor piercing or “bunker busting” meaning the ordnance penetrates the target and continues burrowing down to the heart of a ship or to the inside of a building/bunker etc to destroy the target much more effectively. You don’t see much upon initial impact with ordnance of this kind.
