The Trillion-Dollar Conspiracy: 9/11 Mounting Evidence

LOL, I guess you missed the meaning of the word "ERROR" in the title"ERROR: Seismic Spikes Preceded the Towers' Collapses":

Bollyn's assertions that "seismic waves peaked before the towers hit the ground" and that the ground-shaking energy was "many times more powerful" than the Towers' stored gravitational energy, though interwoven with quotations of scientists, are neither supported by those scientists nor an examination of the events. Consider first the sequence of the waves recorded by the Palisades station.

As the video and photographic evidence shows, the Towers exploded into expanding clouds of rubble that were about 400 feet from top to bottom by the time they reached the ground. Those rubble clouds contained virtually all of the mass of the Towers -- thousands of tons of rubble falling from as high as 1000 feet. That could certainly be expected to produce pronounced seismic waves.

In fact the seismic evidence from the Palisades station comports well with the sequence of destruction evident in photographs and videos: each Tower was consumed by a wave of destruction that started near the crash zone and moved downward as it generated an expanding cloud of rubble. It took about ten seconds for the bottom of this cloud to reach the ground and another eight seconds for its top to reach the ground. Likewise the seismic records show small disturbances lasting for about ten seconds, followed by large spikes lasting for about eight seconds.

There appears to be no basis for the claim that the large spikes preceded the "collapses", nor that the energy indicated by those spikes was more than could be accounted for by the approximately 110 megawatt-hours of gravitational energy stored in the elevated mass of each Tower. And there is strong evidence contradicting the idea that the seismic spikes indicated underground explosions including:

• There is no support in the large body of photographic and video collapse evidence for the idea of powerful explosions in the Towers' basements at the onset of the collapses. Instead the evidence shows waves of destruction proceeding methodically downward from the crash zones to the ground.
  
• Underground explosions would have produced strong P waves, but the seismic stations registered only strong S waves. P waves oscillate horizontally -- parallel to the direction of travel; whereas S waves oscillate vertically -- perpendicular to the direction of travel.
  

Now, we'll see how much intellectual honesty you have.
