About 'The Ultimate Doom'

Hi, there. Something I noticed while watching the three-parter from G1. 'The Ultimate Doom'.
Never once did they say anything to the effect of all humans making it to shelters, or anything like that. We have short scenes of massive destruction, of an entire town being washed away, in one instance. And never once was there any assurance of no casualties.
So my question is, how many people were killed when Megatron used the space bridge to get Cybertron into orbit?
