The Palisades seismic record shows that -- as the collapses began -- a huge seismic "spike" marked the moment the greatest energy went into the ground. The strongest jolts were all registered at the beginning of the collapses, well before the falling debris struck the earth. These unexplained "spikes" in the seismic data lend credence to the theory that massive explosions at the base of the towers caused the collapses.
Does anyone want to help explain this away?
The collapses of the Twin Towers generated seismic disturbances that were recorded by a half-dozen seismic recording stations within a 20-mile radius of Manhattan. Numerous websites have repeated an erroneous interpretation of the seismic recordings as evidence that bombs in the basements of the towers severed the core columns at the onsets of the collapses. One source of this error is an article by American Free Press reporter Christopher Bollyn, reprinted in Serendipity.li .
To the contrary, there was nothing strange about the seismic spikes 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 towers -- thousands of tons of rubble falling from as high as 1000 feet. That could certainly be expected to produce pronounced seismic waves.
An analysis of the timeline of the North Tower collapse on the 9-11Research site corroborates the idea that the large seismic spikes were produced by rubble reaching the ground.

Obviously there is only one thing that could have cuased this.
That the larger spikes of the seismic signatures of the tower collapses were produced by falling rubble does not preclude that the towers were destroyed with explosives. In a typical demolition, numerous small explosives are used to shatter the columns supporting the building. Unless the explosives are detonated simultaneously, they are unlikely to produce detectable seismic signatures. If explosives were responsible for the towers' destruction, they were numerous and were detonated in a synchronized but progressive manner, contributing little to the recorded seismic disturbance.

However, the police did. Hovering over the North Tower following the collapse of the South Tower, Detective Timothy Hayes, in his helicopter, Aviation 14, radioed to his dispatcher, "Be advised - just not 100 percent sure - but it does appear that the top of the tower might possibly be leaning at this time." A moment later he continued, "It is confirmed, it is buckling and it is leaning to the south." "Which tower is that?" asked the police dispatcher, "one or two?" "The remaining tower, the North Tower, is leaning to the southwest at this time," Hayes said, "and it appears to be buckling at this time in the southwest corner."

I posted earlier the amount of force that was released as each tower came down, accelerating as it collapsed with the weight, and created an 'burst of energy' 1/10 the size of a nuclear explosion. It was felt over 250 miles away, and not just seismically. This was not a 4 story apartment building that came down.
With a mass of about 500,000 tons (5 x 10 to the 8th kilograms), a height of about 1,350 ft. (411 meters), and the acceleration of gravity at 9.8 meters per second 2, he came up with a potential energy total of 10 to the 19th ergs (10 to the 12th Joules or 278 Megawatt-hours). "That's about 1 percent of the energy released by a small atomic bomb," he noted.

An idea just came to me now, were the towers originally built in a way to allow for their being destroyed in this fashion? Sounds incredible but we know the NWO crowd works a very long timeline.

Buildings built by Joshua Construction somehow keep blowing up. Max follows Joshua to Las Vegas, where the gorgeous Charlie Watkins (played by Angelique) saves his life. 86 then returns to Washington and goes undercover as a construction worker to figure out KAOS' scheme. He discovers that they are putting nitroglycerin inside the bricks, and then detonating them when the building is completed and filled with people.
Kausel also reported that he had made estimates of the amount of energy generated during the collapse of each tower. "The gravitational energy of a building is like water backed up behind a dam," he explained. When released, the accumulated potential energy is converted to kinetic energy. With a mass of about 500,000 tons (5 x 108 kilograms), a height of about 1,350 ft. (411 meters), and the acceleration of gravity at 9.8 meters per second 2, he came up with a potential energy total of 1019 ergs (1012 Joules or 278 Megawatt-hours). "That's about 1 percent of the energy released by a small atomic bomb," he noted.
The M.I.T. professor added that about 30 percent of the collapse energy was expended rupturing the materials of the building, while the rest was converted into the kinetic energy of the falling mass. The huge gray dust clouds that covered lower Manhattan after the collapse were probably formed when the concrete floors were pulverized in the fall and then jetted into the surrounding neighborhood. "Of the kinetic energy impacting the ground, only 0.1 percent was converted to seismic energy," he stated. "Each event created a (modest-sized) magnitude 2 earthquake, as monitored at Columbia University's Lamont-Doherty Observatory, which is located about 30 kilometers away from New York City." Kausel concluded that the "the largest share of the kinetic energy was converted to heat, material rupture and deformation of the ground below."
