Thirty-eight gravity method estimates of the depth to the pre-Cenozoic surface under Yucca Flat are used to determine the statistical accuracy associated with the gravity method. Results indicate that the gravity method tends to overestimate the depth to the pre-Cenozoic surface, on the average, by 3.5 m with a standard deviation of 75.2 m. N o significant change of this statistical estimate was observed with (1) depth, (2) location, or (3) date when the gravity-method estimate was made.
Density of layer m (g/cm3). plh Summation of the products of density multiplied by thickness for each layer for n layers (g/cm). 9 Angle measured from a horizontal plane through the working point to any radius of the cavity (degrees). R (9) Initial radius of the cavity at an angle 9 (cm). R f(9) Final radius of the cavity at an angle 9. K' Function relating potential energy to overburden pressure. E d Average potential energy function (ergs). Et Total energy yield of the explosion (ergs). K Empirical partition constant for m type of material; K is (i) the ratio of Ed/K'Et' F(9 1) Average force at an angle 9 (dynes). P(9 1) Average overburden pressure for an expanding sphere where conditions for any radius are assumed to be the same as those for a radius at the angle 9. A(9 1) Average surface area of an expanding sphere where conditions for any radius are assumed to be the same as those for a radius at the angle 91. 0 Symbol for 9 equals zero degrees.
Dislocation theory is used in an analysis that explains measured vertical displacements across a fault near the Duryea underground nuclear explosion. The difference between the measured vertical displacement and the theoretically predicted vertical displacement caused by cavity formation is termed the residual vertical displacement. The residual vertical displacement is, therefore, assumed to be the result of faulting triggered by the explosion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
