Just out of curiosity, I plugged the date, time, location into Stellarium and it shows that Jupiter was almost straight overhead, and the moon, sun, and Venus were aligned directly on the other side of the planet at the time of the first quake. So it was Sun - Venus - Moon - Earth - Jupiter in a line. I'm not sure how accurate Stellarium is but it seems like a good astrolab program, so it probably isnt too far off.
