I believe that the collapse of both World Trade Center buildings were =
recorded by the Palisades station, a part of the Lamont-Doherty network. =
 The recording station was 31 miles from the World Trade Center on a =
heading of 012 degrees true.  When you access the site, use the =
following criteria:

    Station - PAL;       Component - E-W;       Frequency Band - =
Short-Period  =20

    Date change is on the right hand side of the page      Previous - =
Next=20

    The first collapse appears the have happened about 1358 UTC (0958 =
EDT) and the second colapse occurred about 1428 UTC (1028 EDT).
