Natural Science Forum / Earth Science / Earthquakes / December 2004

I notice with regret,  that my posting a few comments and questions about
seismology in this Group,  after a long absence,  has resulted in someone
mimicking my name & address and posting utter nonsense as if I had posted it.
Please compare the COMPLETE HEADERS of the silly, ...

           IF YOU REALLY WANT TO KNOW IF THIS WORKS, JUST CHECK OUT VARIOUS
NEWSGROUPS FOR YOURSELF, AND JUST SEE HOW MANY PEOPLE ARE DOING THIS. IF
THAT DOESN'T CONVINCE YOU, NOTHING WILL! ALSO CHECK THIS OUT WITH THE U.S.

To this untrained eye, a relatively large illuminated area is visible
through the background noise which looks like it might be a snow covered
section of the rear crater wall.  If so, there must be a rather bright light
within the crater to source this reflection.  Or something ...

Several stories, one of which can be seen @
http://makeashorterlink.com/?L23E219E9 are reporting the new done at MSH was
split by the 11/27/04 mag 3.1 EQ. As of this time I have seen nothing
regarding this on any of the official MSH Webb Sites, reports by CVO, or

As promised some time ago in some obscure post in some
obscure thread, I have placed audio file version of
recordings from two MSH seismographs.
These recordings contain harmonic tremors. They sound

I couldn't help noticing today that small quakes in the active Parkfield area
of the San Andreas, and the quakes near the 'Oceanic-West Huasna fault zone'
(which runs into the San Simeon fault), are continuing to occur parallel to
each other.   A 2.1 on the 'Huasna' was followed ...

Looking at the 11/29 pictures, I get two distinct impressions of what
MSH's dome is made of. This picture, http://tinyurl.com/5lg93 , looks
like an outcrop of rose granite. This picture of the south end
however, http://tinyurl.com/3mot8 , looks more like mud.

A quarry explosion of 2.3 magnitude occurred during the noon hour today,
11/29/04;  this quarry is evidently RIGHT ON the San Andreas Fault  more or
less half way between the seismically extremely sensitive and vulnerable towns
of Watsonville and San Juan Bautista.

It was no surprise today that the only microquake which occurred in the S. F.
Bay Area, the S. F. Peninsula, the Santa Cruz Mountains or the W. side of the
Santa Clara Valley down past San Juan Bautista, occurred at precisely the spot
I mentioned in an earlier post as deserving ...

Note that a microquake, evidently precisely on the S. A. fault on the San
Francisco Peninsula this morning,  is only a mile or two from the little yellow
square indicating the site of the series of QUARRY BLASTS (the last one, a mag.
2.1 blast on 11/23), at Kaiser Permanente in the ...

Just noted that USGS--NEIC still shows only one significant earthquake as
having occurred in the world on 11/25/04,  (a 5.2 in the Adriatic Sea), which
is implausible because most days show an average of 30 to 40 quakes, or so
(anywhere from 17 to 92, during the past 30 days!)
