The report is the final presentation of Vela Uniform Project 1.01 accomplished on the Long Shot test. Primary objectives were to measure and analyze ground motions in the region above the detonation in light of effectiveness of containment, and to obtain ground-induced water shock measurements at close-in shoreline stations for possible correlation with injury to marine wildlife. A secondary objective was to compare and use for protective structures purposes the results of the ground motions with those obtained from other nuclear detonations in rock. These objectives are considered to have been fullfilled to large degree. Excellent ground motion records were obtained, both surface and downhole, and two of the four water stations produced good data. The weapon was successfully contained despite a surface zero transient displacement of 7.3 feet. The ground-induced water pressure at the close-in shoreline station was insufficient to injure marine wildlife. Modified author abstract
