Reply #12: Do you have evidence to suggest that there is only one seismic

[John Q. Citizen]

event per building?

Loose Change documents two seismic events much later, and before the collapse. It correlates with the audio of two explosions and with the shaking of the video presumably because of the shock wave through the ground from the apparent explosions.

Would the impact of an airliner near the top of the building result in a seismic event? I have no idea. But I can't assume that it would or that it wouldn't.

The eyewitness account claims an explosion near ground level and then seconds later the impact of the plane.

If both the radar/software data and the seismic data presented by the OP are accurate, then there is obviously something going on to cause that. An explosive event would be consistent.
