For the first time, the energy of the induced motion produced during the impact of the first tower has been evaluated as equivalent to those produced by an equivalent Ml 0.9 earthquake located at the WTC site while the motion generated by the aircraft impact at the building top was roughly computed as 0.40m. Here we explicitly simulate the WTC tower motion and its induced effect on ground produced by the aircraft shocks. We show that the induced wave has spectral characteristics corresponding to a higher vibration mode of the building and the nearby ground motion might have high amplitude that should not be neglected during a realistic earthquake.
