But I can assure all that at my home here in OKC, there were TWO distinct reports separated by a second or less in time, and the second report was larger. Kinda of a "boom..BOOM!".

One of the Seismology centers somewhere near there reported 2 seperate shocks 8 seconds apart. The first one being far less than the follow on shock. This was reported very early on on the day of the bombing. By late afternoon that story was completely gone from the mix.

IIRC, University of OK seismographs picked up two distinct shockwaves, also.

They were later explained away as having been some sort of reverberation or refraction effect.

I am a geologist, not a geophysicist per se, but I didn't buy it. Two explosions, two shockwaves.
