A new article and a new letter at the Journal of 9/11 Studies
At the Journal of 9/11 Studies, we have published a new article and a new letter. That makes 2012 as productive as our past three years at the journal combined.
This month's article is from Dr. Andre Rousseau and is titled "Were Explosives the Source of the Seismic Signals Emitted from New York on September 11, 2001?"
The conclusion states: "Near the times of the planes' impacts into the Twin Towers and during their collapses, as well as during the collapse of WTC7, seismic waves were generated. To the degree that (1) seismic waves are created only by brief impulses and (2) low frequencies are associated with energy of a magnitude that is comparable to a seismic event, the waves recorded at Palisades and analyzed by LDEO undeniably have an explosive origin. Even if the planes' impacts and the fall of the debris from the Towers onto the ground could have generated seismic waves, their magnitude would have been insufficient to be recorded 34 km away and should have been very similar in the two cases to one another. As we have shown, they were not."
The letter is in response to an article that was previously published at the journal. It is from Tod Fletcher and Dr. Tim Eastman, and is called " The Pentagon Attack in Context: a Reply to John Wyndham."
Here is an excerpt: "A broad-based analysis is needed to understand the Pentagon events – an analysis that is based on the full range of available evidence and therefore cannot be exclusively scientific in a narrow sense. This is especially important due to the fact that physical, quantifiable evidence is extremely limited, while there are multiple related events and information that can contribute helpfully to addressing (and providing context for) the problem. Thus, we have emphasized the superiority of a systematic contextual approach that builds effectively on such related information, and the need to treat the limited available evidence within its associated context. Further, we have emphasized the need to leverage the best established results, including attention to the likely means, opportunities, and motives of perpetrators."
In December, we expect to have more to share.
