Loud Mystery Booms Reported Across Sections of Westmoreland County, Pennsylvania-July 18, 2021
From Researcher: Stan Gordon
There were numerous reports from the public reporting an extended period of loud explosive sounds that continued to occur periodically between approximately 11 AM and noon. At times, single booms would be heard about 10-20 seconds apart. There were long series of continuous rolling thunderous sounds reported as well.
I was told the sounds were audibly very loud around South Greensburg, Jeanette and near Youngstown outside of Latrobe. I understand that local residents from such locations as Greensburg, Hostetter, Norvelt, Latrobe, and Hannastown were posting comments about the incident on social media.
One witness I interviewed who has an extensive science background was certain that what he heard was not fireworks. He drove in his car to try to find the source of the sounds but was unable to locate it. He said the sounds were so intense he could feel the booms resonating through his body.
I have not seen any data suggesting this was weather related. There were no storms in the area at the time. The extended time that the occurrence reportedly was taking place seems to eliminate a sonic boom.
I am not aware of any local events that might have been utilizing any type of fireworks, cannons, etc. for an extended period of time.
From the current information I have, the boom sounds were heard across an approximately 11 mile area.
Addendum:
The mystery boom phenomena has been occurring since at least the 1960s. There have been many such incidents reported across Pennsylvania and the country even in recent years. There are manmade and natural explanations for many of these incidents, however some past cases remain unsolved.
I am keeping track of such incidents. Please contact me if you heard the booms, and also please let me know of any possible sources for these sounds.
