The problem is where you draw the distinction.
What about a person or animal who is not killed by the shock wave but may by
thrown the ground, either by compressed air or ground movement? Would that
meteorite be considered a "hammer?"

What about sound waves that travel through the air as a meteorite flies
overhead and reach a human eardrum, thus producing a "sound?" Technically,
the compressed air impacted a human eardrum, so would that meteorite be
considered a "hammer."

What about a clod of dirt thrown up in the impact, hitting someone's shoe?

Speaking only for myself, I draw a distinction between a person, animal or
man-made object who is actually hit, or makes physical contact with the
meteorite vs. not. Nothing, more.

Besides, one could also argue that neither the blast wave nor the bomb
actually killed our hypothetical person. It was the bomber who actually
killed the person. Then we open up another can of worms, so-to-speak.

Keep it simple. Did the meteorite itself actually hit something?

Hi Bob...

Bomb blasts were introduced as a way of ramping into a discussion of
shock waves. Be it a bomb or an extraterrestrial impact, we're
talking about the rapid compression of environmental air pressure.

Let's look at Meteor Crater as an example. The impactor was a
fraction of the size of the crater; the volume of the crater was
primarily the result of shock waves; and we refer to the impact having
been responsible for the entire crater.

In fact Meteor Crater is of course referred to as an IMPACT crater. No
one makes the distinction of what aspect of the crater touched the
molecules of the impactor.

Returning to Carancas, I don't understand the distinction that a
bull---real or imagined---isn't considered "impacted" by the very same
shock waves responsible for the overall size of the "impact crater."
It's revealing that a casualty which results from shock waves created
by a bomb are defined as Primary Blast Injury. It seems logical the
same nomenclature will be applied to the first person who is a little
too close to the impact of cosmic debris.

Anyway....

Two points:

Does anyone know whether shock waves crated by an object the size of
Carancas could have been sufficient to have killed a nearby bull?

At least in the case of Valera, we know the "shoulder" (thoracic
vertebrae and scapula) were crushed by the impactor.


PRODUCT ENDORSEMENT: All of the aforementioned words were fueled by
Red Bull.
