Some witnesses near the World Trade Center feel the ground shaking just before the South Tower starts to collapse:
bullet EMT Joseph Fortis is heading across West Street, when, he says, “the ground started shaking like a train was coming.” He then looks up and sees the South Tower starting to collapse. [City of New York, 11/9/2001]
bullet Lonnie Penn, another EMT, is outside the Marriott Hotel, which is adjacent to the North Tower. He and his partner “felt the ground shake. You could see the towers sway and then it just came down.” [City of New York, 11/9/2001]
bullet Bradley Mann is at the EMS staging area on Vesey Street. He says, “Shortly before the first tower came down I remember feeling the ground shaking. I heard a terrible noise, and then debris just started flying everywhere.” [City of New York, 11/7/2001]
bullet Battalion Chief Brian O’Flaherty is walking into the lobby of the Marriott Hotel. He says, “I hear a noise. Right after that noise, you could feel the building start to shudder, tremble, under your feet.” He then hears the “terrible noise” of the South Tower collapsing. [City of New York, 1/9/2002] Witnesses will also notice the ground shaking before the North Tower collapses (see Shortly Before 10:28 a.m. September 11, 2001).

The South Tower of the World Trade Center collapses.The South Tower of the World Trade Center collapses. [Source: Associated Press]The South Tower of the World Trade Center tilts to the southeast and then collapses. It was hit by Flight 175 at 9:03 a.m., 56 minutes earlier (see 9:03 a.m. September 11, 2001). [Washington Post, 9/12/2001; New York Times, 9/12/2001; MSNBC, 9/22/2001; USA Today, 12/20/2001; Associated Press, 8/21/2002; ABC News, 9/11/2002; National Institute of Standards and Technology, 9/2005, pp. 44] The first sign of the collapse is visible on floor 82. [National Institute of Standards and Technology, 9/2005, pp. 87] The angle of the tilt will be disputed after 9/11 (see September-November 2005), as will the time it takes the towers to fall to the ground (see September 12, 2001-September 2005).

Some witnesses feel the ground shaking just before the north WTC tower starts collapsing:
bullet Fire Patrolman Paul Curran is in front of the US Customs House (WTC 6), next to the North Tower. He says, “all of a sudden the ground just started shaking. It felt like a train was running under my feet.… The next thing we know, we look up and the tower is collapsing.” [City of New York, 12/18/2001]
bullet EMS Lieutenant Bradley Mann is heading toward the EMS staging area on Vesey Street. He’d felt the ground shaking prior to the first collapse (see Shortly Before 9:59 a.m. September 11, 2001). He says, “The ground shook again, and we heard another terrible noise and the next thing we knew the second tower was coming down.” [City of New York, 11/7/2001]
bullet Jay Jonas is actually inside the North Tower, on its fourth floor. Seconds before the collapse he feels “a tremendous vibration and shaking; the floor began waving.” [Providence Journal, 9/11/2002]

Carol Marin.Carol Marin. [Source: Columbia Journalism Review]CBS News correspondent Carol Marin witnesses what she describes as a “gigantic fireball” coming from the base of the North Tower as it starts to collapse. [USA Today, 9/11/2001; Chicago Sun-Times, 9/12/2001; Daily Herald (Arlington Heights), 9/11/2002] Marin headed to the scene of the attacks and arrived on West Street after the South Tower collapsed. She then sees the second tower come down, later describing, “I was only a block or two away from the North Tower when the street trembled under my feet, a fireball of pooled jet fuel exploded out of the building’s base, and it too, unbelievably, started to collapse right in front of me.” [Chicago Sun-Times, 9/10/2006] (However, the explosion could not be due to “pooled jet fuel,” as, according to the National Institute of Standards and Technology, “The jet fuel” from the planes “was mostly consumed within the first few minutes after impact.” [National Institute of Standards and Technology, 6/18/2004; New York Times, 4/5/2005] ) In one telling, Marin describes, “a roar seemed to come out of the earth,” causing the fireball. [Gilbert et al., 2002] In another, she says, “there was a roar, an explosion, and we could see coming toward us a ball of flame, stories high.” She runs, and a firefighter throws her against a building to protect her. She recalls, “The flame somehow stopped short of us.” [CBS News, 2002, pp. 54] Other witnesses also describe the ground shaking before the North Tower collapse (see Shortly Before 10:28 a.m. September 11, 2001). And some witnesses similarly report seeing a fireball at ground level coming from the South Tower when it collapsed (see Shortly Before 9:59 a.m. September 11, 2001).
