Abstract
The time of first arrival of seismic waves generated by four underground nuclear explosions at the Nevada test site and recorded along a line extending north into southern Idaho is expressed as TD = 0.00 + DELTA /3.0 (assumed), T1 = 0.40 + DELTA /6.03, and T2 = 6.15 + DELTA /7.84, where time is in seconds and the shot-detector distance ( DELTA ) is in kilometers. Constant velocities and horizontal layers were assumed, and the crustal thickness in the vicinity of NTS was found to be 28 km. Delays in the travel-time segment T2 , which represents Pn, indicate that the crust may thicken to 32 km in northern Nevada. A third phase, expressed as T3 = 14.48 + DELTA /7.84, was also recognized. It has arrival times appropriate for SPS. Amplitudes of P were determined at seven places from recordings of seismic waves from one underground nuclear explosion.
