(Please see our FAQ on this subject at AE911Truth.org:

Yes. It is beyond doubt that the seismic data recorded by Columbia University’s Lamont-Doherty Earth Observatory (LDEO) in Palisades, New York, corroborate the eyewitness, video, and forensic evidence of explosions both before and during the collapse of all three WTC towers — and explosions even before the plane impacts into the Twin Towers. Our conclusion, which is based on our review of the studies conducted by the researchers and seismic experts listed below, match the LDEO’s seismic data. But because the LDEO did not rely on its own data when it issued its report, our conclusions do not match the LDEO’s conclusions. Thus, our conclusions also contradict the conclusions of the FEMA and NIST reports, which relied upon the LDEO report’s conclusions and not upon the original seismic data.
We also recommend that you read the article, “Point TT-7: Why Did the Twin Towers Collapse? The Seismic Evidence,” by the 9/11 Consensus Panel.
