Collier County residents have reported feeling earthquake-like shaking.
The source of the shaking Sunday morning is not known and there have not been any nearby earthquakes documented.
The Naples Daily News reports callers to the Collier County Sheriff's Office and newspaper readers have asked about the shaking.
JuLynn Mott told the newspaper that "the whole entire panel of the sliding door from my living room to lanai started shaking."
She said the shaking continued for about a minute.
