Kathy Hotchkiss is a legal assistant on the tenth floor of 55 Public Square.
HOTCHKISS: "I just saw the walls start to move, like kind of sway, the wall in front of me. And then I felt a little uneasy and there was like the sensation of rocking in the floor. Not an intense rocking, but kind of a swaying rocking, if you will."
Several buildings in Cleveland -- including 55 Public Square -- were evacuated shortly following the quake as a precaution. No injuries or damage has been reported. Dr. David Pierce is a geology professor at Lakeland Community College. He says the shaking tends to be more pronounced higher up in buildings.
PIERCE: "You'll get the shaking at ground level, but that gets transferred through the building too. And the higher the building is, the more it's going to wave, the more it's going to move. It's going to transfer all that energy through the structure of the building, and then you're going to get subsequent movement from that. So the people higher up will have a tendency to feel it I believe more so than people on the ground."
Dr. Pierce felt the shaking at his office as well.
PIERCE: "I was on the third floor of Lakeland Community College, and it really felt like someone was pushing on athe building, almost like when you dock a boat and you get that residual wave effect. And it was kind of a long duration, from 10 to 15, some people say 20 seconds long. It seemed to keep rolling."
Sarah Kresnye works at the Center For Community Solutions on the third floor of the Buckley Building in downtown Cleveland.
KRESNYE: "It felt like the room was spinning. I actually put my fan on because I thought I was going to pass out, and we could feel the building shake and everybody sat silent for a minute, and then everybody came out of the woodwork, you know - did you feel that, did you feel that? We all said we felt the same thing, that the room was spinning and we were going to pass out. And it turns out there was an earthquake."
Seismologists will be analyzing data from a network of research stations and should have a better sense of the earthquake by Thursday.
