I'm no geophysisist but in Terra Nove T'pol said that an asteroid hit about 500km from the colony and shot down to a depth of 2000m. It seems to me that if an object hit hard enough to dig that far down, that close to the colony then they all should have been wiped out by the blast and thermal shock. I don't think that radiation would have been a problem as thay all would have been dead. Secondly this would have been a global disaster but they said that the southern continents were clean. Any thoughts on this subject. Paul

Did she say how big it was? that would probably make the difference.

Given some basic information like impact crater size and amount of original asteroid material left and other data from the impact site, geologists can get a pretty complete idea of what the asteroid was and thus what affect it had. It's done here on Earth all the time. Of course, an asteroid wouldn't bury itself beneath the surface, it would create a crater of empty space around where it hit.
More bad science. Yay.

I interpreted that scene totally differently, and since my tape is hours away, I'll have to just babble and pretend to remember.
T'Pol wasn't talking about how deep the asteroid itself got. They were trying to gauge the severity of the impact, and she mentioned that there was evidence of...what...thermal shock? Or maybe some sort of fissures...anyway, evidence of some sort at a depth of 2000 meters. She certainly did not say that the crater itself was 2000 meters deep.
Incidently, it is fairly hard to find information about the geology of terrestrial impact sites that is detailed enough to be useful (in this case, for purposes of comparison) but not so detailed as to make my head explode.
