At the tennis tournament on Yale's campus, 71-year-old John Ricci's first thought was of the stage collapse at a concert in Indianapolis earlier this month. More than 4,000 people were evacuated during a match between Jelena Jankovic and Elena Vesnina. Spectators felt three waves of shaking, as water bottles sloshed back and forth.
Vesnina was leading 2-0 and about to serve, facing two break points. Jankovic looked up in amazement as spectators rushed from their seats. Seconds later, the chair umpire suspended play.
"On the court, we didn't feel anything, but I saw the upper level, and it was shaking. I said, `Oh, my God, what is going to happen?'" Vesnina said. "I was really scared."
New Haven firefighters carrying axes walked in and out of the stadium to the applause of fans waiting outside the main court. The fire marshal later deemed the structure sound and let fans back in more than two hours after the tremors hit.
Play resumed at 4:15 p.m. when chair umpire Sandie French said, "Ladies and gentlemen, this is the resumption of play of a match suspended because of an earthquake." Fans in the stands chuckled, and Vesnina prepared to serve.
New York Jets general manager Mike Tannenbaum was sitting at his desk when the team's training facility in Florham Park, N.J., shook for a few seconds.
"Usually when the building shakes, Rex is laughing, so that was my first instinct," Tannenbaum joked later.
But it wasn't guffawing from the Jets' boisterous coach, Rex Ryan. When Tannenbaum peered out into the hallway, about 50 people were standing there, "with everyone kind of looking at each other like, `Was that really an earthquake?'"

At home before the Yankees played Oakland, Nick Swisher said he was "wondering why things were moving in my living room" on the 21st floor. His thought: "Hey, I'm getting down on the ground." Once he reached the street, Swisher ran into teammate and neighbor Dave Robertson.
Greensboro, N.C., native John Isner was upstairs in the stadium at the Winston-Salem Open men's tennis tournament when his mother said it felt like an earthquake.
"And I was like, `Come on, Mom, there aren't earthquakes in North Carolina,'" he said.
"I thought somebody was doing construction nearby, so I got on the Internet, and it was up and down the East Coast," Isner added.
