THE FIELD EQUIPMENT
The Seismograph Unit
The seismograph unit used at WCU is the SmartSeis, a 12-channel exploration
seismograph manufactured by Geometrics, Inc. The built-in computer and
menu-driven software makes the unit easy to use in the field. Menu options
include standard set-up parameters that can be easily modified, rapid display
of digital signals, and options for infield processing of data to show
interpreted depths to subsurface layers. Floppy and hard drive storage and a built-in
printer allow for easy storage and transfer of data. (For more information on

The Cable
Seismic Energy Source
We use a simple sledgehammer f or our energy source. On the body of the hammer there is a
trigger taped to the up side of the handle. This is connected to the trigger extension line and then
connected to the SmartSeis. A
metal strike plate is used in conjuncture with the hammer.
