Hi all:

The exerpt below was sent by a friend of mine in Tucson.  Thought the group 
might find it interesting.

"Dear Bob,

        I have a pretty good story to pass along to you. You may 
remember Gordon Wieduwilt who was a local geophysical contractor here in
Tucson for many years. He is now mostly retired, works about 1/4 time 
out of a small office in his home. He was down in Mexico last week doing
a gravity survey and at one station he had a terrible time getting the 
meter to stabilize so that he could take a reading. He turned it off and
on several times and still the same peg-to-peg needle deflection.

        Finally he realized that a large earth quake was probably in 
progress somewhere. It turned out the be the one in Turkey last Thursday
afternoon. It took the shock about 103 minutes to arrive in northern 
Mexico which works out to about 6,000 feet per second.

        I'd be curious to know if you detected that one as well. Maybe 
we don't need seismometers but only gravity meters."
