A mystery ‘boom’ that ‘may not have been explosion’ caused panic in northeast Philadelphia and Lower Bucks County at approximately 9:30 PM, May 27, 2011, according to a local NBC report, with multiple fire trucks, EMS, and power companies racing to the ‘scene’. After reaching the area, no one could locate the source of an explosion. Also reported, house’s shook which led to speculation it may have been an earthquake. According to NBC 7 the USGS was unable to confirm the boom was an earthquake. Other speculation, a sonic boom which was heard in only northeast Philadelphia and Lower Bucks County.
NBC 10 Philadelphia video news report:
‘Calls and emails flooded NBC 10 News after reports of several loud bangs. This is in northeast Philadelphia and Lower Bucks County. Fire and emergency units raced to the scene but it is still not clear what has happened here.’
The local NBC reporter:
‘This is a very strange situation out here you can see behind me there are multiple crews from the fire department and the police department as well as crews from PECO and PGW. This is the area of 9th and Fairdale Rd. in Northeast Philadelphia. Here’s what we know, at about 9:30 tonight the fire department started getting multiple calls of what some people described as a possible explosion. Some people I’ve been talking to at the scene said that it actually felt like a minor earthquake. Whatever it was at this point investigators have not been able to determine what that explosion was or if it even was an explosion but people said it lasted only a few seconds.’
One witness: ‘It sounded like something above you, fell down.’
Another witness: ‘It sounded like something hit the building, like a car. It was just a shake and that’s when the cops and everything were here. And someone said a house blew up and everyone came running out and no one knows what it is.’

Excellent reporting. PICI is a ski resort in Vermont. You will have to show me where 9th and Fairdale intersect. It’s called fact-checking.

Haha. I meant PICO. Should have spell-checked.

I live in N.E. Philadelphia and I was in my house and I randomly heard a loud rumble and my house shook for a few seconds. I didn’t know if it was just me or not so I asked my mom if she felt and heard it too and she said she did. Then firetrucks and helicopters were all over the place. :/

sonic boom perhaps in Philadelphia?

This would account for the shaking as well as the loud explosion-like sound.
