ABERDEEN, MD—A loud explosion was felt in many parts of eastern Baltimore County on Wednesday morning.

At around 11:30 a.m., the Baltimore County Fire Department says reports began pouring in regarding a loud boom and homes shaking.  NottinghamMD.com received dozens of reports from Middle River to Parkville to Kingsville.

The source of the explosion was an ordnance detonation at Aberdeen Proving Ground.

APG had a single detonation scheduled for between 11 a.m. and 1 p.m. on August 4th.

“Noises may be heard in some areas off the installation,” reads the official announcement.

The Baltimore County Fire Department and Baltimore County Police Department have each confirmed that an APG ordnance explosion was the source of the loud boom.  Officials say Wednesday’s low cloud deck allowed the noise to travel farther than usual.
