Quote:
The magnitude 7.1 quake on Friday night in New Zealand was larger than the one that killed 200,000 people in Haiti this year and appeared to have opened a new fault line.
Mark Quigley, a geology professor leading a team investigating the cause of the quake, said: "One side of the earth has lurched to the right."
“Up to 11 feet in some places has been thrust up. The long linear fracture on the earth’s surface does things like break apart houses, break apart roads.
"We went and saw two houses that were completely snapped in half by the earthquake.”

So all the GPS systems will now be off target.

The GPS coordinates will be correct. It's the maps that need updating; even the good old paper maps will now be wrong.

I'd imagine that accurate cartography is fairly low on the list of '[LIFTED] that needs sorting' in Christchurch, however.

All the land based GPS markers will have moved, so that doesn't have a relationship with GPS co-ordinates?

What do you mean "land based GPS markers" - do you mean for TomToms etc??

This is not something I've ever thought about. I guess they need fixed reference points?

Fixed points on a planet where all the plates keep shifting is a rather impermanent concept!

I though all coordinates were base on the central meridian than runs through Greenwich, ie Zero degrees.

It also depends on the direction of the movement.

A 7.1 quake? Any idea what that is on the Richter scale? I don't uderstand the new scale, other than an earthquake seems to be a couple of points higher on this new scale...
