Quirks

Hebron, Newfoundland is 60 degrees north and 60 degrees west.

Savannah is on an arc something like 30 degrees from Hebron. It’s on the south west coast of the North Atlantic.

On the north east coast of the same ocean lies Britain. And on the North West extreme of the arc centred Hebron, lies the source of the Alaskan bay lows that cross the Rockies:

The perimeter of the disc (radius 30 degrees) follows the eastern edge of the Rockies, going through Yellowstone from the Mackenzie river in Alaska. Then it hits the Platte; then on through Kansas between Topeka and Wichita through Arkansas, Alabama near Columbus and out on the border of Georgia and South Carolina between Savannah and Charleston.

And North of Britain it skirts Norway, hits Spitsbergen and passes pretty close to the North Pole.

All interesting places.

When the Low comes ashore at (for example) Alaska from the North Pacific, it splits up as the constituents fall apart. Then as the various acoustic waves go their own ways (ask: “Why?”) they tend to drop the overall pressure of the now attenuated and extensive Low in the Midwest to not much less than 1016 millibars -the sort of stuff that is associated with tornadoes (funnily enough.)

And then from all directions they (said diffused waves) gather towards the coast just off the place where the Gulf Stream’s current is at its most powerful.

OK?

Now let’s widen it out.

As a Low or for that matter an High leaves the continent at Georgia or the Carolinas, there is a dramatic increase in the magnitude of the earthquakes that occur near the Rat Islands on the Aleutian Archipelago. The number of quakes usually drops and the somewhat frequent incidence of magnitude 1 and 2 tremors become two or three 2.5 to (occasionally) 4 to 5 Mag quakes.

And these of course are 80 degrees from Savannah and Charleston. And 60 degrees from Hebron, Newfoundland.

Giving Hebron the man’s number so revered by idiots who aught to check their facts carefully. And what does this all mean?

Blowed if I know.

I don’t know what it all means but I am glad I am able to dispense with the 80 degree ratio between that part of the North American coast of the south-eastern USA.

A 60 degree radial arc gives us that shadow zone beloved of seismologists. Apparently because of the Mohorivicic discontinuity and its ilk, sound waves are supposed to disappear in the region 105 to 135 degrees from what most think is the epicentre of and for want of a better word: “Earthquake”.

(I’m quite happy with the term “earthquake”. I just wanted to make the point that several other terms need rethinking.)

Well. That’s another anomaly. Let’s see what not thinking about it for a few years will supply us with.
