How is that even possible?

Latitude is always parallel to the equator and perpindicular to longitude, which always extends from one pole to the other.

When California experiences 'The Big One' and Los Angeles slips several miles west into the Pacific ocean, you are suggesting that a waypoint I captured pre-event will somehow still retain the same coordinates after the event?

Ridiculous!
