For Earthquake, the two LDs have the original Sensurround mix according to the LDDB forum. The initial pan n'scan has a stereo track that actually was the original transferred directly (so you can even hear the control tones present), and the later widescreen release simply converted the mix to Dolby Surround.
Correct. Laserdisc and Sensurround guru Ty Chamberlain has also confirmed the Sensurround cue tones are also on the original DiscoVision LD pressing of BATTLESTAR GALACTICA.

So the widescreen Superman LD has the 35mm Dolby Stereo mix without split surrounds?
Yes- I don't think the ultra-rare 70mm mix with split surrounds was ever used for home video. Certain elements from it were "occasionally" borrowed for the creation of the new 5.1 remix, per some interviews, but outside of those occasional snippets, the 70mm split surround mix has been MIA on home video.
