Modeling of body waves recorded at teleseismic distances has shown that the fault causing these earthquakes has a thrust mechanism with small strike slip component on a roughly northeast-southwest trend (Figs.
Since the earthquake's magnitude 4.2 body wave was much smaller than the magnitude 5.3 explosion, the color coding for absolute energy values is not directly comparable for the two events.
As a result, an explosion tends initially to radiate mostly compressional or P (for primary, since P waves arrive at seismic stations before other body waves) body waves, which produce an upward and outward motion at the earth's surface.
The debate over yield estimates was reportedly rejuvenated within the government this year after two advisory panels to the Department of Defense (DOD) considered the use of surface waves -- seismic signals that travel along the surface of the earth--in addition to the body waves
now used in yield estimates of big explosions.
has accentuated the lower frequency harmonics to create music that goes beyond the auditory system to be felt in the body.
