```Jerry,  You've got that right................This is my slowest month =
for a year, day after day very uninteresting screens.   Maybe tomorrow?
Since I have no earthquakes to discuss...........Could this device be a =
support for a large dia. pipe?

As a part of a Seismic device, here is my suggestion:
Get a large piece of white butcher paper 48" x 48" Draw a center point =
on the piece of paper, using a black #2 pencil, connecting two opposite =
diagonal corners.
Carefully position one corner of the paper facing true north and the =
opposite corner south.
Place this device in the center of the paper and align it's support =
shaft along the N/S axis.
Trace the profile of the entire device on to the paper using the black =
#2 pencil.

Wait for a large earthquake, >7 M, closer than 100 miles.
After the large event, retrace the new position of the device's profile, =
using a red #2 Pencil.
Comparing the original position profile with the new position profile, =
one may be able to plot the general direction of the epicenter, and =
estimate the magnitude.  Unless it move greater than 24" from center.
Thanks,=20

OK, Meredith.  I give up and curiosity has got this cat.  It reminds =

question and there seems to be a lull right now in EQ's.  Let's stir up =
some discussion!
