A magnitude 4.0 earthquake centered 20 miles northeast of Cleveland shook some buildings and overwhelmed the emergency communications system of a small town.

It was not clear right away if the earthquake had caused damage. The US Geological Survey said that it had struck at 10:50 am and that it was centered north-northwest of Eastlake, Ohio, a city of about 20 000 inhabitants located on Lake Erie.

"Please, do not call the dispatch except in case of emergency," said Eastlake Mayor Dennis Morley, in a message posted on Facebook. "They are inundated with calls, it was a magnitude 4.0 earthquake and the security forces are working to help where it is needed."

The Perry Nuclear Generating Station, about 20 kilometers northeast of Eastlake, said the plant did not seem to be affected by the shaker.

"Workers perform a full visual inspection to ensure that the state of the factory equipment does not change," said the factory director in a statement .

The state's transportation department has watched some very shaky videos from its road cameras.

"Did you feel that rumble this morning Cleveland?" the department tweeted. "Well, if you missed it, we were hit by this morning's earthquake with several #OHGO cameras.
