Project DANNYBOY was a 430 ton nuclear cratering explosion in basalt. The Coast and Geodetic Survey measured surface earth motions in terms of displacement, velocity and acceleration at 12 locations from 760 meters to 340 kilometers from surface zero. Multiple regression of maximum earth particle displacements and accelerations from DANNYBOY and four other cratering explosions are given. Author
