Training Classes and Familiarization
Demonstration of seismometer preparation prior to installation.
Karl Thomason demonstrates the preparation of a
seismometer prior to installation. Successful installation of
these instruments requires a special procedure adapted to
borehole installation. Instead of adjusting instrument level
and free period after installation, it must be preset prior
to the installation in a borehole.
During the site preparation for the 9 element arrray, a
training class was held to demonstrate the technique and
familiarize seismologists with the procedure.
This training session included both instruction in the software
and analysis of the data at Dallas as well as installation field training
At the time
of this visit, only one telemetered site was in operation
(the prototype). Visiting technicians learned the methods
needed to completely install a system and to diagnose
Visiting delagates visit the operational Lajitas Site
In 1995, a fully operational TXAR hosted
delagates from Russia in a familiarization visit. Here Paul
Golden explains the geometry of the Array using a high altitude
color infrared photograph. Air and satellite photos are invaluable
in selecting sites and access roads. Even in this location, where
detailed 1:24000 scale topographic maps are easily available, a photo
is an essential tool.
