You're talking about wandering shifts, rather than massive shifts, & wandering shifts are of no consequence for a deluge event, so drop it.
I'm talking about the kind of event that left the Siberian mastadon quick frozen in ice with preserved daisies in mouth & stomach.
Axis shifts & EM pole reversals go together often (massive shifts OK?). EM pole reversal alone is not necessarily a deluge event, except that it causes lava production. But along with axis shifting massively, it's surely a deluge event.
I never said reversal alone would cause deluge, but reversal & shift go together. I'm not even saying the great flood was a shift event, but it's proof earth has been deluged before is the point.
Shift waves last less than a week before settling down. That's why I'm with the tidal pull flood scenario.
