Do Seismic Records Really Show that the Towers Fell in Ten Seconds?
Because the claim that the Towers fell in ten seconds has historically been uncritically repeated by defenders and detractors of the official story alike, most newer researchers have not taken the time to closely examine its validity. The idea that seismic records from distant recording stations could be used to establish the duration of a building collapse or demolition is highly questionable on its face given the complexities inherent in interpreting seismic data, such as the indirect relationship between ground movement at a source and and at an observatory miles away. Nonetheless, the assertion that seismic records from observatories such as that in Palisades establish that each Tower collapsed within ten seconds is widespread.
