Update: Did A Loud Boom Just Shake Your House?

Just before 8 a.m. Monday morning, residents throughout Cranston felt a boom that rattled windows, shook houses and sent car alarms and pets into a frenzy.

Cranston Police Chief Col. Marco Palombo said police are investigating the cause of the boom in response to media inquiries, but so far, the search has turned up nothing conclusive.

The chief tweeted that Cranston Police is coordinating with Johnston Police to find a cause. Either department can be called with reports.

"PD encourages residents to call in to assist," Palomobo tweeted.

So far, numerous people in Cranston have reported hearing or feeling something.

"Shook my house in Knightsville," said Paula Violante Gabriele.

"In Woodridge, it sounded like a backhoe bucket hitting the ground," said Karen Salisbury Wischnowsky.

Theories have ranged from the demolition of the former police station on Atwood Avenue, a landfill gas burp of some kind, industrial blasting or even a natural occurrence known as cryoseism, or a frost quake, when frozen groundwater rapidly expands and cracks soil or rock.

So far, police have ruled out blasting at PJ Keating off Phenix Avenue. Company officials say they haven't conducted any blasting in more than a month and has no plans until April 2014.

Demolition of the former police station began at 7:05 a.m. but no explosives were used.

And Rhode Island Resource Recovery said nothing happened at any property near the Central Landfill in Johnston.

"We've heard reports of booms too, but we know that they're not happening at our facility," a company official said.

Police actually did not get any phone calls relating to an explosion or other significant noise and there was just one reported house alarm between 6 and 8:30 a.m.
