Interesting observations. Add in gas fracking in the region, and you've got
another "trigger".

In 1985, I predicted the Mexican earthquake based on approaching Hurricane
Terry. That ended up being a magnitude 8.1. I could see the hurricane
tracking across the Pacific Ocean for days, and the path was headed directly
for a fracture zone. I believe the hurricane started an underwater
landslide that sent a large amount of debris into the fracture and set it
off. All it takes is a submersible to prove it later... In the VA case, I
believe gas fracking may be more important as a trigger, but add in the
weather systems, and other earthquakes that are happening and that put
pressure on other faults, then you may have a perfect set-up for these
quakes.

Today as I'm sure many of you know, two earthquakes occurred
in the US, one right at the Kansas/New Mexico border with magnitude
5.3, later in the afternoon, (UTC), a 5.8 magnitude in Virginia near
Wahington DC.

These are magnitudes that I personally have not seen
in these areas, but they might occur at _long_ intervals as is known.

They are not high magnitude. The recent 6+M in Japan was more
inteeresting as it was one of the first of that size to occur in the
last few months without an anticyclone in the NE North Atlantic.

The probability being that it would have been greater if all the other
related weather patterns had remainedin force whilst the extra one(s)
in the N Atlantic occurred.

But what is strikingly apparent is that at this PRECISE
instant the worst hurricane since 2008 (which was Ike) is born in the
Carribean and is fast approaching the US east coast. Just north
of Hispanola at the moment. Name: Irene.

If someone were to tell me these three events were not related, I
don't know what I would do probably just laugh.

It remains to be seen just how far apart a set of weather systems need
be to increase the potential of an earthquake. What is becvoming clear
is that the multiples make a mockery of contemporary magnitude
estimates.

Failing one cyclone/anticylone, a mag 6 becomes a mag 5 or whatever.
But this doesn't mean a Mag 5 is one step less than a mag 6 does it?

If you lookat the current and recent lists on the NEIC pages, you will
sooner or later notice two or three consecutive quakes of similar
magnitude on the list. All within a degree or two of the epicentre of
the first. They may be minutes apart or a few hours.

These usually tell the end of a large storm.

But the storm doesn't have to be a tropical one.

Look how a Chilean or Aleutian earthquake occurs when a weather
system leaves or arrives in the Virginia / Carolina (N+S) region.
Invariably it is a matter of some 80 degrees in that case. But there
are other weather systems too, having an associated impact.

All that needs be done is to take a look at the weather world wide for
a series of such and you have the magnitude point differences.

And can come up with inverse square laws for them.

(If there is that much difference with distance. They say that swells
don't lose their power but whoever "they" are, probably do not take
account of the fact that waves are tidal (as are earthquakes.) Look
how many mutts on sci.geo.earthquakes still adhere to the principle
that harbour waves are not tidal waves.)

I am in a state of mind now that I don't get upset by them being
stupid. It took a while but when I realised I was knocking on heaven's
door I also realised I'd be leaving them all behind.

My job is to not step in the dogczjd whilst I am so close to the
threshold.
(Or not, as the case may be.)
