Avy classifications?

Another serious JONG question, but I'm learning some stuff. :D

Could someone translate this please?

From CAIC's description of an accident:
We classify this avalanche as HS-AM-R3-D2-G

I'm gonna guess hard slab something reutchshchblock 3 something or other?

Not mentioned, R# is size of avalanche with respect to the slide path, and D# is the destructive potential of avalanche.

thanks.
