There is an interesting theory about earthquake “reflection”, that large earthquakes can cause other large earthquakes *perpendicular* to the on the ring of fire.
That is, if you imagine the ring of fire as a big circle, people might think that if you have a big earthquake on one side of it, you might have a reflexive earthquake on the other side. But that only rarely happens.
However, perpendicular to it, on the same side of the circle, reactive earthquakes seek to have with fair frequency.
If this is the case, the big Chilean earthquakes might reflexively trigger a big earthquake anywhere from California to Alaska, inclusive.
The “Crust Reasonance” theory? There was a 4.2 ESE of Acupulco (I forget the name of the city) last night, hours after the Chile 8.2’s 6.1 aftershock.
That would fit into the perpendicular theory.
Well, I was typing the ^above^ post to you, a 5.2 on Pacific coast of Panama. Seems the Americas’ side of the Ring of Fire is rattling pretty good.
I hope the ‘ring’ of this bell doesn’t do anything to the Cascadia Subduction Zone. That’d really make my day suck.
