SALISBURY TWP., Pa. — A loud boom heard from beyond Allentown is nothing to worry about, according to Salisbury Township Police.
Residents reported hearing a loud boom on social media Wednesday evening, sharing a text that was "a public notification" from Police Chief Donald Sabo.
"There will be a series of disposals from an emergency call in Lehigh County near Riverside Drive," the text reads. "Noise/bang may travel with the cloud cover and rain along the river. Lehigh and Northampton County 911 Centers have been notified of the possible calls after this event."
Some residents shared they heard it as far as Hanover Township and also in Bethlehem.
EPAWA meteorologist Bobby Martrich said today's weather is to blame for the sound traveling so far — "there's a significant temperature inversion."
Higher up in the air, temperatures are typically cooler, but today, temperatures are warmer, Martrich said, which traps the sound below the inversion — because "sound is always trapped under inversion" — where it echoes and reverberates, thus traveling farther"
Police told LehighValleyNews.com over a phone interview Wednesday night that "there is no active incident or anything."
The notification was sent out to those in the vicinity as "another agency" carried out the disposals within Salisbury Township, police said, but that "it had nothing to do with our agency."
Police said they were made aware of the event, but had "no clue" as to what was disposed of.
In 2022, emergency call centers were flooded with calls from concerned residents after TNT was detonated by the Allentown Bomb Squad, also in Salisbury Township, off of Constitution Drive.
