A fire alarm sounded and scores of people spilled from the sprawling office complex and shopping center into the street, where they texted loved ones and pressed their phones to their ears.

At California University of Pennsylvania, "We definitely could feel it and hear it," said spokeswoman Chris Kindl, who was working in a building adjoining Old Main on the campus when the quake occurred.

It lasted for about 30 to 40 seconds and shook the house enough to make the walls creak. . . . However, everyone here, including the seasoned earthquake pros from California, was quite shaken up. No pun intended."
