BLANCA-A STUDY OF THE MAXIMUM VERTICAL EARTH MOTION OF THE MESA SLOPE. T echnical M emo No. B-214 (Revised)

Technical Report ·
OSTI ID:4194710

Blanca, a 23 kiloton device, was detonated October 30, 1958, in a tunnel in Area 12 of the Nevada Test Site. The point of detonation was a vertical depth of 988 ft; the nearest point to the surface on the mesa slope was 835 ft. First apparent earth motion appeared approximately 3.6 sec after zero time; the maximum earth upheaval was reached approximately 5.5 sec after zero. Approximately 15.9 sec after zero, an earth rupture occurred on the mesa slope. (W.J.H.)
