Abstract : Stress, particle velocity, and acceleration data were obtained from a 140-ton nitromethane row-charge detonation in a saturated clay-shale. The charge row consisted of two 40- and three 20-ton spheres (first and fourth charges were 40 tons) extending S 11 W from the Pre-GONDOLA I Charlie crater on an 80-foot spacing (first charge 105 feet from crater center). The primary instrument line (stress and particle velocity gages) extended S 79 E from the center charge (G) with gage stations 100, 150, 200, 300, and 400 feet from G. Gage depths were 10 and 50 feet except the 400-foot station which was gaged at 50 feet only. Acceleration measurements were made on the slopes of the Pre-GONDOLA I Delta and Charlie craters and at the Control Point (CP).
