World Trade Center 7: 47-Stories Created A 0.6 Seismic Impact

A 0.6 seismic reading can be referred to as a "microearthquake" and is of such a low magnitude that it is indiscernible from natural tectonic origins. How can a 47-story building be destroyed and leave a seismic signal that is not distinct from natural causes?

SEISMIC IMPACT FOR WTC 1 (110-stories, 500,000 tons): Local Magnitude (ML) 2.3 -- without p-wave or s-wave
SEISMIC IMPACT FOR WTC 2 (110-stories, 500,000 tons): Local Magnitude (ML) 2.1 -- without p-wave or s-wave
SEISMIC IMPACT FOR WTC 7 (47-stories, 230,000 tons): Local Magnitude (ML) 0.6 -- without p-wave or s-wave

For a forensic study of what happened to seven World Trade Center buildings on September 11, 2001, read the book "Where Did The Towers Go? Evidence of Directed Free-Energy Technology on 9/11" by Dr. Judy Wood, a structural engineer with a Ph.D. in Materials Engineering Science and expertise in experimental stress analysis, engineering mechanics and strength of materials testing.

_______
Dr. Judy Wood earned a Ph.D. Degree from Virginia Tech and is a former professor of mechanical engineering. She has research expertise in experimental stress analysis, structural mechanics, deformation analysis, materials characterization and materials engineering science. Her dissertation involved the development of an experimental method to measure thermal stresses in bimaterial joints. Her research has involved testing materials, including complex-material systems, in the area of photomechanics, or the use of optical and image-analysis methods to determine physical properties of materials and measure how materials respond to forces placed on them. Her area of expertise involves interferometry in forensic science. She taught graduate and undergraduate engineering classes and has authored or co-authored over 60 peer-reviewed papers and journal publications in her areas of expertise.

In the time since 9/11/01, she has applied her expertise in materials science, image analysis and interferometry, to a forensic study of over 40,000 images, hundreds of video clips, a large volume of witness testimony, analyses of dust samples, seismic data, and the analysis of other environmental evidence pertaining to the destruction of the World Trade Center complex. Dr. Wood has conducted a comprehensive forensic investigation of what physically happened to the World Trade Center site on 9/11. And, based on her analysis of the evidence she gathered, in 2007, she filed a federal Qui Tam case for science fraud against the contractors who contributed to the official National Institute of Standards and Technology (NIST) report about the destruction of the World Trade Center towers. In December of 2009, this case was filed in the US Supreme Court. To this day, Dr. Wood's investigation and body of evidence as compiled in her book is the only comprehensive forensic investigation in the public domain. WHERE DID THE TOWERS GO? is not a book of poetry, yet it has some beautiful prose. It is not a novel yet it tells a complete story. It is not a photography book, yet the pictures will grab you. It is not just a text book, yet its data is empirical and it teaches critical thinking. It is not the Bible yet it will be one of the most important books you will ever read.  http://drjudywood.com
