A quick note about foreshocks and/or the current CA/NV map of eqs and the collapse of a bit of Hwy 1.
Foreshocks are almost always noticed after a larger quake. And, in only 10% of eqs, are there anything which could reasonably called foreshocks/preshocks. Often, when there are foreshocks, they are thought to be "the main" event until something larger comes along. It's inexact, and if we in CA were to think every X-richter scale shake was a foreshock, we'd be in continual concern.
Jim Berglund is an interesting character. I've followed his theory, used to get his newsletter and he's pretty decent in terms of forcasting. however, he's not 100%. The "scientific community" tends to poo-poo him, but I don't think that's smart...he's been right enough for me. But remember, just because he said it, doesn't mean it will happen. It's just more likely than not. Living in EQ country, though, makes it more likely that not, too. KWIM?
As for the collapse of part of Hwy 1 into the Pacific, from what I understand, that area did get some higher waves and surges, along with strong tidal pulls, from the tsunami. To me, it's more likely that the Hwy went down because of the washout of the underpinnings of ground during the tsunami after-effects than because of an unmeasured eq. Just mho, of course, but it's more reasonable to think that rather than believe it's a sign of impending eqs.
The fish, otoh, is worrisome.
It is my firm conviction that all the energy from the 9 in Japan has put amazing pressure on the opposite side of the ring of fire. Meaning, of course, the west Coast of the US. Energy doesn't disappear; it changes forms, or it goes somewhere...but it doesn't just go away. I've long thought that there is a sort of ricochet of energy, depending on various factors (none of which I know...), that sets up other areas for quakes.
Do I think this weekend will bring a big one to the west Coast? Perhaps. I think that this weekend is more likely to see one than say, any other weekend, both because of the full "super" moon (Berglund's theory accounts for this), and because of my own ricochet ideas.
Does this mean I'm heading to, say, Illinois? Nope. But it does mean that between the radiation potential, and a few other concerning things, I am making another run to the market tonight. Worst case scenario, I will have suppplies. Best case scenario, I won't have to go to the market for an extra week or so.
