Elongations are the meteorological terms for ridges and troughs when air masses change from Highs and Lows with circular cross sections to ellipses and then into tongues joining "like" pressure systems. …
There is quite a deep Low in the Alaska Bay and a not so deep Newfoundlander on here:
The problem is a flaccid High separating them.
With no real storms going on in the tropics and the NEIC pointing to some stuff pending, that leaves us with the North Atlantic and the Southern Hemisphere charts to look at.
Nothing over 4.9 M. between here:
5.2 M. Off E. coast of North Island, N.Z.
5.1 M. Queen Charlotte Islands
The North Atlantic:
Which brings us to the way we understand elongation.
Obviously weather can not cause weather, and since the weather is so intimately connected to the behaviour of earthquakes, it stands to reason they don't cause themselves either. Nor does one cause the other; no more than they are caused by tides.
Which brings us to what causes tides. All that Poincaré; Lord Thomson; Geiky, Darwin and the rest of them ever proved is that we don't know much about tides. They don't follow the moon, for even in the age of supercomputers homo-sapiens in all his glory can't follow the moon, how much less insensible water?
All we do know is that a super-normal mechanism releases the tides to fall behind the clock as though by some universal chronometer regulator. What mighty power this is we don't yet know.
Talking of universal regulators:
The "deep Low in the Alaska Bay and a not so deep Newfoundlander" above are the next signal to us that a large quake is imminent. Actually it is no such thing. A third (middle) Low is required. And this has to replace the High there at the moment. But as there IS a quake due, I am guessing it HAS to appear there.
An absence of large quakes means that a larger one still is due. The lack of a small run of 5 Ms means we will have a 6 M. to make up for it:
"Since the weather is so intimately connected to the behaviour of earthquakes"
Dry or wet, the weather pays its debt
Large or small, earthquakes average overall.
The run of charts on the North Atlantic show a Low in dissolution. This fits the overall picture of not a lot happening in the tropics but doesn't tell us much about what is due.
I won't repost any of them. But you can see two pairs of Fronts on the first two charts and then the weather breaks up. This is common with twin earthquakes.
But there should be a reasonably noticeable quake in the Fijian triangle setting up another bout. There are black (thunder) fronts on each chart too. Also symptomatic of quakes but I am not sure how, except that they mean the air is still enough to allow cumulo-nimbus:
The Antarctic runs on the other hand are quite interesting, they contain stuff I have only observed a very few times. I was not then able to draw any conclusions from such behaviour. I am not going to try now…
