Magnetic Orientation North: Rapid changes?

Doesn't the declination of magnetic north usually change yearly? Perhaps I am missing something? Can I ask, what is the unit of measurement for the x-axis? (I see that it is time, but how rapid per "tick"? It seems to jump from June to July...)

anyone?
iv not seen this but for after the recent earthquakes
the quakes in the alutian islands and the kermadec islands on the 25/06 and the arizona quake on the 29/06 seem to have shifted something....

but what could the 15/07 be?

but it shows some changes in direct oposition in the graph for 23/06-16/07

I'll ask again...

That graph, do you know what the units for the x-axis are? I can see a change from roughly 46 to roughly 47 in the time of about a month, and then it seems like the tail end of the data is about 45.5 or so... Are these outside of known fluctuations within the time spans indicated by the x-axis?

the change seems to happen between the 25/06 and 14/07, so around 20 days.
there were alot of threads regarding earthquakes and magnetic north on.the 25/06, il find them.

here is a link to the data

easier to make out
it says degrees......
but so i assume at its magnetic north up is true north, and down is south?
hard to say
im not sure what to say
i noticed this in observing a tilt in yellowstones geyser tabel, and a drop of pressure on the pressure sensors.
madison river also seemed to have a large shift in water volume and temprature.
iv never seen the orientation change on this equipment until last week

I'm sorry, I'm unfamiliar with this type of graph... I'm still not sure what the units are for the x-axis, and I know the y is in degrees, but I'm not sure degrees of what... Maybe the angle made from a line drawn from that location to the northpole with respect to that location's longitude? (I really hate unclear graphs.) If that were the case, it wouldn't be fluctuating all that much, and the tail end of the graphical data indicates a southward (lessening of the angle) movement.

That said, I don't know what the lines on the graph mean. I assume they are statistical representations of how confident one can be with the data... (Probably 95% certainty that the true location is within the entirety of the field covered by the lines from any time.) If that's the case, there could really be even less of a change with anomalous data pushing the seemingly second section of the data upward for some reason...

Without knowing more about the graph, I can't help. Sorry.

for somebody who can help

anyone got anything on this?

lol, its fucking days on the bottom and degrees on vertical math wiz

i was trying to explain that by giveing the dates.....
i dont think that was understood lol

you have made it clear haha

now what does it mean when theres a shift of around three degrees seen in 20 days?

so nobody?
this doesnt mean anything?

Let the sky fall....
