Philadelphians react to 6.0 magnitude earthquake (PHOTOS)

Crowds gathered within minutes on Penn Square after pouring out of City Hall and surrounding Center City skyscrapers. Here’s some reaction from the masses who waited in confusion for about 45 minutes before heading back to work — well, most of them.

“I’m just worried about the children at home for the summer. My grandkids are probably sitting around saying ‘what the heck’. They don’t know what an earthquake is.” Yvonne Harris, 54, financial specialist

Jeremy Krafchin, who works on the 25th floor of the Comcast Center, said he thought “someone was moving a large piece of furniture for about 30 seconds.” Krafchin said everyone on his floor evacuated the building, but “was pretty calm.”

“I thought we were about to be attacked. I was on the 46th floor and that was the first thing you think of,” said Tasha Odom, who works in the Comcast Center. “You don’t think of an earthquake. It was scary.”
