nor will i change my stance that there are positive trajectories, or alternaticely, that the DEGREE of lateral ejection could not be caused by any 'plunger'.
remember, everyone, that the speed of sound is not the same through the earth as it is through the ground. when things don't sync between recordings of vibrating air, and vibrating earth, it is not obvious what has transpired.
i know that the seismic traces for the big collapses were 8 and 10 seconds in duration, respectively. and for tower seven, it's like 20 seconds.
it is my contention that ONLY BOMBS are making the earth shake, signifigantly, and the tons of material hitting the earth are relatively insignifigant as seimic-creating events.
do i know that this blitz is ongoing, and a LEARNING MACHINE? oh, yeah.

I think you are reaching well beyond the standards of reliable scientific method, if you are trying to assign a 1 to 1 relationship between a specific portion of the collapse event and a specific portion of the seismic signal.
But if you have to go that route, consider that the penthouse collapse was the topmost indication of a failure that started on the 6th or 7th floors or so, and probably involved the weight of a significant portion of the building plunging through the substation vaults.
I believe the sounds just paled in comparison to the considerably higher ambient noise as compared to Hoboken. Also, there should be much more diffusion in the city.

Plus, you can hear two rather distinct, low frequency thuds - how's the motorbike supposed to generate those?

Also, the page has this, which is definitely accurate:
Demonstrated infrasonic weapon
The U.S. DOD has demonstrated phased arrays of infrasonic emitters. The weapon, about the size of a truck, usually consists of a device that generates sound at about 7 Hz. The output from the device is routed (by pipes) to an array of open emitters, which are usually one wavelength apart. At this frequency, armor and concrete walls and other common building materials vibrate, and therefore provide no defense. The frequency is chosen to be near the resonant frequency of internal organs, causing illness, deafness, and internal injuries. The resulting weapon is the size of a truck, fragile, and has a shorter range than missiles or artillery shells.
In an attempt to refute the original claim that there were no explosions....in the video "In Plane Site" there is footage from CNN that was broadcast only once on sept.11 and never after, this shows a plume of smoke rise appx. 50 stories in the air, before either building collapsed.

okay, i checked it out.
now, the way that the LOW FREQUENCIES can be emphasized, without making the MIDS AND HIGHS HARSH AND OVERBEARING, is by splitting the audio into multiple narrow bandwidths, exactly the same as a crossover network in a speaker column. once the frequency bands are seperated, they can be processed individually, bass, mids, and highs.
