[EAS] WEA used in NYC bombings

[Clay Freinwald]

John Willkie has written some 'good stuff' about earthquakes - Likely that
anyone except those of us that life on the Left-Coast will experience.
A couple of thoughts to share - 

> The Pacific Northwest Coast (PNW) is projected to experience a major quake
in the future.   This is based on the geological evidence that these take
place periodically.   The magnitude is projected to be in the vicinity of
9.0.   The amount of devastation that this will cause will make all Sandy
and Katrina look like a sprinkle.  For more information Google -  Cascadia
Rising.

> Other that thougher building standards and not building in areas that will
certainly liquefy there is not much you can do other than ride it out when
it takes place when it takes place.  A lot of people will die simply because
they were on the wrong place at the time.

> The best thing one can do in this area is to prepare for it by having a
bullet proof safety plan and survival materials for a long (think at least a
month) living without anything that we have become used to.   Consider what
you would need if suddenly you were transported back 200 years - and you had
to rebuilding your shelter.

> While you are looking at Google Earth thinking about escape routes for
California Cities - Take a look at Seattle and let me know what you think.
During the last major quake we had in this area we had mud geyser's in the
middle of the runway at Boeing Field 

> Remember that there are no prediction technology that we can integrated
into EAS.    For those of you that look at the Event Code-EQW - and think
'Warning'  ....Sorry.  This code was created, at the request of the
Washington State SECC (and others) as a means for dealing with the events
-AFTER the quake.

> The recent Cascadia exercise demonstrated that EAS and the majority of
broadcast stations, as well as WEA will be silenced.     This is why we are
now working on EPIS (Emergency Public Information System) that will enable
EOC's to access certain broadcast transmitters for the purpose of providing
the public with vital information.   We project that only a handful of radio
transmitters might be viable after the event (forget their studios).    The
information vacuum is going to be huge and the longer this goes on, the more
critical it becomes.   This has the potential to become a law enforcement
problem of epic proportions.    You've seen the postings of Phil Johnson on
this system, he is leading this effort with the full support of the
Washington SECC.  Those in earthquake country would be wise to do the same
thing.

> Just to put things in perspective - In this area we have signs that many
of you don't have, representing potential issues that you will never
experience -  Those signs - 1) Tsunami Warning - 2) Lahar or Volcano
Warning.   And yes those signs could well be co-located.     Think about it.

>From my limited knowledge, virtually all earthquake waves are supersonic,
some >14,000 mph.  The idea as I understand it is to use supersonic
electronics that report the first shock to points that won't feel the shock
at remote locations until some time (seconds) later.  From experience, the
waves tend to diminish over distance, depending on geology.  The Easter
Quake(s) of a few years back (epicenter 100 miles distant) were deep, and
the epicenter was basically on sand and alluvial fill; residents there
mostly reported smooth waves.  To me, in San Diego, on more solid ground, we
felt sharp shocks, but with less up-and-down than in Calexico.

I think it's an open question as to whether such short-term notifications
will help much, absent "the big one," which could come any hour, day, week,
month, year, decade or century. 

Anyone who has ever been at a vantage point when even a moderate earthquake
hits tends to remember "terra firma" undulating like a rip current as the
earthen waves go through.

Any earthquake beneath the ocean within 100 miles of land that causes a
large tsunami won't give people along the coast enough warning to even kiss
one's a** goodbye.  Fire Island might be remote, but look at Coronado, CA on
Google Earth.  Note the two routes in/out: a bridge (2-3 lanes out) and a
12-mile route over a glorified sandbar to the South.  <24 feet above mean
sea level.

This was discussed a few weeks ago on one of these EAS lists.

A simple explanation of the earthquake warning system is that there is a
supersonic shock wave that precedes the actual shock wave. This means that
the earthquake has commenced. The time between these supersonic waves and
the Main shock can be seconds. The problem with public warning is the
latency in the various warning systems would not always get the warning
through in time.

Interestingly enough our ancestors had an early warning system. Over the
time they observed that dogs went crazy just before a quake. Basically they
were responding to the same supersonic pre-tremors that EEW is exploiting.
So if you want EEW with low latency, stay close to your dog.
