André Rousseau is a Doctor of Geophysics and Geology, a former researcher in the French National Center of Scientific Research (CNRS), who has published 50 papers on the relationships between the characteristics of progressive mechanical waves and geology.

„The seismic signals propagating from New York on September 11, 2001, recorded at Palisades (34 km) and published by the Lamont-Doherty Earth Observatory of Columbia University (LDEO), have here been subjected to a new critical study concerning their sources. The aim of this paper is to demonstrate that the nature of the waves, their velocities, frequencies, and magnitudes invalidate the official explanations which imply as sources the percussion of the twin towers by planes and the collapses of the three buildings, WTC1, WTC2 and WTC7.“
