(meteorobs) Superbolide energy vs. meteorite drop

[Jure Atanackov]

With regard to large fireballs and superbolides - I've been studying and 
reading a lot about superbolides and meteorite impacts lately and it seems to 
me that most of the recent significant meteorite falls come from (as far as 
superbolides go) rather unspectacular events with <0.1 kt energy, for example 
the Mbale, St. Robert and Villalbeto de la Pena. Park Forrest (~0.5 kt) and 
Tagish Lake (>1.5 kt), probably also the recent Carancas event seem to be 
about the most energetic events associated with recorded meteor drops.

Is there a certain mechanism that prevents larger objects measuring in tens of 
kilotons, such as the Mediterranean event of June 6th, 2002 or the Marshall 
islands fireball of February 1st, 1994 up to prehaps Tunguska size to produce 
substantial meteorite drops or do such events produce proportionally larger 
meteorite drops measuring in tons and tens of tons, but are just very very 
rare?

Clear skies!
Jure
