Seismic records was recorded at each event, details have been withdrawn and kept secret. Lamont-Doherty Earth Observatory only had only two stations running for WTC events 1. PAL and 2. BRNJ..
The two stations are kept in wave form only so select a station and date 9/11/2001.

Lamont-Doherty Earth Observatory defined the 9/11 events as
"Nuclear Explosion Seismology" and be found via keywords "Nuclear Explosion Seismology"

"is not possible to infer (with detail sufficient to meet the demands of civil engineers in an emergency situation) just what the near-in ground motions must have been."
Again
Seismic waves generated by aircraft impacts and building collapses at World Trade Center, New York City.
But unfortunately, we also conclude that from the distance at which our own detections were made (the nearest station is 34 km away at Palisades) it is not possible to infer (with detail sufficient to meet the demands of civil engineers in an emergency situation) just what the near-in ground motions must have been.

"A "sharp spike of short duration" is how seismologist Thorne Lay of Univ. of California at Santa Cruz told AFP an underground nuclear explosion appears on a seismograph"
So why Did Won-Young Kim became so interested in underground nukes after 9/11?
