Detection of Distant Explosions by Seismic Measurements in Deep Boreholes
Description:
Report presenting the results of a program of research on the depth-well method of obtaining improved signal-to-noise ratios in seismic recordings. Experiments were conducted comparing simultaneous measurements of seismic signals in adjacent cased and open boreholes. Design and performance features of a moving coil geophone for borehole use are described. A balldrop method of geophone calibration is described. The improvement of signal-to-noise ratio with depth for the first ''P'' arrival was d…
