Alle ore 15 di oggi (28 aprile) il numero di eventi della sequenza sismica in Italia centrale ha superato i 65.500 dal 24 agosto 2016. Negli ultimi giorni in media vengono localizzati tra i 100 e 150 eventi giornalieri, pochi di questi hanno magnitudo uguale o maggiore di 2.

So I scrolled around, looking for more info on this particular tectonic region. Am I correct in presuming we're talking about an event around the triple-junction area known as The Queen Charlotte triple junction? Described as such:
"[snip]....geologic triple junction where three tectonic plates meet: the Pacific Plate, the North American Plate, and the Explorer Plate. The three plate boundaries which intersect here are the Queen Charlotte Fault, the northern Cascadia subduction zone, and the Explorer Ridge...."
Another interesting tidbit:
"The Explorer plate is a small chunk of the Juan de Fuca plate that broke away from the Juan de Fuca Plate about 3.5 Ma and has moved much slower with respect to North America."
That made this SoCal Gal sit up and shriek, "JUAN DE FUCA SAY WHU?!?" Oh. Yeah. I'll be concerned about this Alaskan EQ swarm now.
So I went to some maps. Lots of maps. Compared maps and more maps. Let's talk about the North American Plate, shall we? Talk amongst yourselves while I copy/paste this:
"The westerly boundary is the Queen Charlotte Fault running offshore along the coast of Alaska and the Cascadia subduction zone to the north, the San Andreas Fault through California, the East Pacific Rise in the Gulf of California, and the Middle America Trench to the south."
SAY. WHAT?! I've heard a couple terms I DON'T want to hear in the same breath: Juan de Fuca and San Andreas. How have I managed to manipulate this Alaskan EQ into MY PROBLEM?? (Right? That's what I asked myself, anyway.) Here's this:
I think in pictures, and I learn by visualizing. I keep seeing a Zipper thing in my mind-- what is that? If I turn this info that I am reading into a math problem like 2+2=..... It certainly seems like my area of the plate is going to start shakin' rattlin' and rollin'.
Peace and Love.
Also- I am going to be perusing every boobtube channel I can find, with regards to this latest development. (Learning about EQs on my own takes much more time, now that Muzzy is .....muzzled....) Second parentheses remembered.

I wonder if there have been any changes in the Molten iron river discovered speeding beneath Russia and Canada Back then it had trebled in speed back on December 2016.
Notice in the picture below that the jet passes through Alaska, among other places. (the molten jet does not passes under Japan, although boundary plates will be affected by the molten jet increase in speed)
