Police from Flat Rock have deemed the town all clear; no sign of what caused the mystery boom
More than a dozen residents called Flat Rock police to report hearing a loud "boom," that some said shook their houses just before 9 p.m. Wednesday night.

After hours of searching the areas that people reported the noise, which was loud enough to cause some residents to say their houses shook, nothing was found.

By 11:30 p.m. the city was deemed "all clear," without the cause being discovered. Police in Gibraltar, Huron Township, Rockwood and Monroe County were also alerted to the noise, but nothing was discovered in those communities either.

Hundreds of people from Newport to Taylor flocked to social media, posting on Facebook, Twitter and other sites about hearing the noise, feeling the vibration and speculating as to the cause.

"Sounded like a bomb went off," Flat Rock resident Jen Emerick said. "I live on Palmetto."

Dozens of others echoed her comments on the noise level.

"I live in South Rockwood and it was so loud here felt like a truck hit my house and my house is brick," Ruth Apperson said in a Facebook post.

Fred Tanner said it was so loud that he felt it in his "insides."

"Shook the house, and our guts," he said.

As quick as the word of the "boom" spread, speculation started as to what caused it. No official explanation has been given by officials in any of the areas it was heard in.

One rumor that was quickly spread was that a meteorite had struck the area around Huroc Park, people in the area quickly squashed that, which only lead to more speculation as to what had actually happened.

...We have also learned in this series that the frequent reports of unusual booms and shaking of the ground is often due to such overhead [meteorite] explosions. Yet the media steadfastly refuses to honestly address this issue[...]

Other people speculated that it was the cause of mining at the local rock quarry, or underground blasting in the salt mines. Another popular theory was that it was a "frost quake."

Frost quakes usually occur in cold weather as water freezes though, not after several days of warm weather.

Investigation into what happened continued into Thursday.
