The floor in part of Boston’s City Hall appears to have buckled, creating what looks like a safety hazard, at the very least.
The crack occurred around 3:30 p.m. on the second floor of the building, near the birth and death certificates service windows.
The Boston Globe reports:
"This is a result of a concrete underneath the floor tiles expanding and contracting," said mayor's spokeswoman Kate Norton. She said it was the third or fourth time it had happened in recent years. ... She said the buckling was the result of "concrete underneath the floor tiles expanding and contracting."
Witnesses reported seeing as many as 50 tiles damaged in the shakeup.Caesar can be reached at Christopher.Caesar@globe.com or via Twitter @ChrisCaesar.
