A number of things have been buzzing through my head today. Not least among them is that I was caught with my pants down once again. …
From these links: San Francisco State University you can work out two things:
1. The relationship with earthquakes and weather is related to the angle of incidence on the globe.
2. That if there are two storms arriving, leaving or arriving and leaving, at the same time the intensity of the quake increases.
I am in a bit of an hole with this one though as there are just too many weather features leaving the continent and too many quakes occurring on it to allow me, with my limited knowledge of the subject, to really form a picture of what is going on.
But something occurred to me this evening when I was wondering where to start with this blog. I'd noticed that the incidence of one with the other is that a front leaving North America seems to have a diagonally opposite reaction with the related quake. In other words:
If the air mass leaving the continent leaves from Newfoundland, the quake is likely to occur in Mexico or California.
If the mass leaves from the southern US states, the quake will be in Canada or Alaska.
So I was looking at that deep Low over the Baltic last night and wondering what that meant. I should have known. Baltic state Lows are related to Indonesian activity.
Then the penny dropped. The relationship isn't so much that Continental N. America is wrapped with the angle of 80 degrees and that Eurasian ones are wrapped around with 120 degrees. The angle is the measure of the continent involved.
Eurasian quakes are related to the Eurasian weather almost exactly the same way as the North American ones are. What a dunce!
Why did it take me so long to see that?
I deserve a good kicking!
I just thought it was something to do with shadow zones. I wonder if the explanation for shadow zones is the land masses involved. What an absolute dummy!!!!!
Unfortunately, the angular distance is something like 55 degrees from the storm ccentre roughly over Tallinn,Estonia:
Just because it doesn't fit my preconceptions doesn't mean it's true though.
