Station:‘123. 03 was located 15,925 feet from GZ on » reef between
Charlie and Dae.
Low tide was at 0736 on shot day, leaving most of the
gage mounts-above the water level. To explain the extremely high
horizontal or yadialacceleration at this station we must consider that
the gage and gage ‘mount acted as a pendulum when the shock wave passed
over it. This reading was of no value to ground acceleration, but it
is probably an explanation for the failure of some of the pressure-time
gages and the distortions of their records.
The vertical acceleration
is probably a truer value, in magnitude of actual acceleration. The
shock Wave was impress
in a coincidental plane with the gage and
gage mount, with the ort)preef acting as a baffle to the gage itself.
