The societal reaction regarding seismic activity during the collapse of WTC 7 played a critical role in ongoing investigations. Observers highlighted that the seismic readings at the time were low—insufficient to suggest a major structural failure or explosion. Many reports indicated that the collapse of such a large building should have generated a significant signal on seismic records, yet analysts noted no substantial evidence of vibrations that would be consistent with a typical demolition scenario.
