Thanks for this, blam.
IIRC, Quix asserted that such was true to Strategerist who dissed the idea quite strongly.
I think Quix had read an obscure expert’s article and felt it was correct. He may have been already nudged in that direction from his prophecy studies.
Strategerist maintained his typical naysaying stance on such ideas very staunchly.
Score one for Quix.
Wouldn’t the P and S Shadow zones actually determine the spherical angle transmittable? Look at coordinates for the Chengdu big one(s) and the subsequent 6.x in Iceland. (something like 100 around and 35 up)
I don’t have the math, data or knowledge to calculate it, but it seems like any next quake could fall on a line from the first quake point along the edge of the liquid core to the surface (twin circles)(as the S wave would go)and ‘generally’ across the earth center-solid core for the P wave. (so ~180+/- deg) And if the arriving power found a susceptibility there, a quake would be generated. Which could be smaller or maybe bigger depending on the situation there.
USGS uses tensors and displays them graphically in their world chart. Also, I just discovered that if you click the world map at the pole it will display a hemispherical map and you can see a little easier how the earthquakes form lines along, I assume great circles rather than through the core. If the planet were a uniform sphere the patterns might be easier to develop. I attended Real Analysis class and Complex Analysis class with some of these competitive personnel, quite a challenge.
