2.11.2 Procedure
Bull plugs containing Wianko accelerometers for detecting the
magnitudes of the vertical, radial and the tangential components of
earth acceleration will be installed approximately 15 ft below the
earth's surface. The three components of acceleration-time will be
orded at an underground shelter by means of Ampex tape recorders.

2.12.1 Objective =
To make a comparison of effects of a classic, dust free,
shock front with effects observed at the KIOTHOIE operation, in order
to assess dynamic overpressures’as a damage parameter.
2.12.2 Procedure
For comparative purposes (@ s will be deployed in the region
of 20 psi side-on pressure and 14%S side-on pressure. These ovcrpressures are calculated to produee’theyoane dynamic pressures which
at KNOTHOLE produced severe damage andj ight demice respectively.

—
A few jeeps may be exposed on Shots:'Unjon and Yankee. No entry
will be required after Union; however, low level aerial photographs
will be used to record the damage. The main'partieipation will be on
Shots Echo and Koon. Entry after the shots will ibe necessary to record
damage.
