What I worrier me more is how silent the US West coast has been for a while. The hardest it's seen has been a 4.6 in the past 30 days. If you go
further south there has been 5.5. But that fault line has been pretty still for a few year now.
I mentioned a couple of days ago that I think we should be looking for movement along the West coast, leading up to California. It seems logical to me
that such a considerable movement in the Pacific plate would have an impact around it, and my layman's view was that we might see movement spreading
along the boundary in either direction.
Shortly after saying that, we've seen three EQ's further up the West coast in Panama, Nicaragua and Mexico. This is while there is still considerable
movement being seen further south in Chile.
In addition to that, there was seemingly heightened activity to the North in Alaska too.
I'm no geologist, but it seems to make sense to me that such movement in Japan, spreading through and along the rim of the Pacific plate, would lead
to a travelling ripple of activity which is approaching the opposite side - California.
Like I said, I'm no geologist, but from what we've seen said about the events in Japan, I believe this was different to anything we would normally
associate to a quake of that magnitude. People there reported an extremely powerful quake, and we've seen the damage it did, in a country pretty much
more prepared than any other for this kind of thing. There was something about this which was very different to what we would normally associate to a
quake in that region at that strength and I have no idea what it was.
Perhaps it was the angle of movement, maybe the depth, maybe the plate causing it directly rather than an off-shoot, but something caused the land to
shift about 25cm, and upward too.
I hope I'm wrong, and I'm sure brighter minds are looking at this and saying it's a simplistic theory without any validity, but from my limited
education on this common sense tells me there is a ripple of sympathetic movement running along the rim of the plate and it's about to reach
California in the next couple of days. Depending on how sensitive faults are and how ready some might be to slip, we could see minor activity or
something more dramatic.
I'm betting that over the next couple of days we'll see activity increasing along the West coast of the US, I just hope it's minor and does nothing
more than relieve the pressure in that area.
