Firefighters, EMS respond to mystery booms heard in Philadelphia, May 28, 2011
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 PICO 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.'
