Studies of the travel times, periods, and energy of seismic waves SKP and related phases
The travel times, periods, and amplitudes of SKP core waves have been investigated for shocks of normal, 60 km, and 100 km depths. For shallow shocks, multiple SKP phases are observed as long as 54 seconds after the initial SKP motion on short period instruments, and as long as 87 seconds on long...
