Hi Mike,
I think of "hammer" as a term that collector's use to organize their
collections and dealer's use to market their meteorites. As such "hammer" is in
the eye of the beholder. I don't think there will ever be a universally
accepted definition. I admire you for trying to nail down a definition however
I think you have a hopeless task ahead of you.
Thanks,
Peter

Subject: [meteorite-list] Chebarkul - Chelyabinsk - Is it a "hammer" ???
Hi List,
Quick question for hammer collectors :
If meteorites are recovered from this event, and these recovered meteorites did
not actually strike anything manmade, would this fall still have any reason to
be labeled as a "hammer" ?
Does damage from an impact shockwave count towards this fall being a hammer?
I know this is sticky issue to some - the term "hammer fall" is not widely
accepted and it's validity has been hotly debated on this list previously.
This Russian event is spectacular for many reasons and does not need to be
"promoted" to hammer status if it doesn't deserve such status.
Possible labels for this fall :
1) fall (of course)
2) witnessed fall (duh!)
3) observed fall (yes)
4) hammer fall (? - questionable at best)
5) crater-maker (does a hole in an ice-sheet count as a "crater"?)
6) wake-up call : time to start seriously considering an effective system to
detect these "small" threats which fall under the size-detection threshold of
larger observing networks. It's amazing that an object with the power to
flatten a city slipped through undetected, despite most of the world's
telescopes being pointed upwards for about a month preceding the impact.
Best regards,
MikeG
