Updated 1:42 p.m. May 1 to include observation from NNCS science teacher.

Houses reportedly shook from as far as Ogdensburg to Massena accompanied by a large boom at around 10:30 a.m. Tuesday, but according to the United States Geological Survey, an earthquake did not cause it.

Some have speculated the sound and tremors to have stemmed from aircraft, but calls to media contacts at Fort Drum have not yet been returned.

St. Lawrence County Emergency Services received at least two calls regarding the sound and tremor, with one call coming from the Ogdensburg area and the other from Madrid. On Facebook residents in Waddington and Norfolk also reported feeling the shockwave and hearing a thunderous sound.

Emergency services said because there was no visual accompanying the sound and the distance at which was felt, it was unlikely to have stemmed from an explosion.

Dispatchers did not want to speculate on the cause, but said it is possible it could have been caused by aircraft.

A Norwood-Norfolk Earth science teacher reached out to North Country Now and said a number of people at the school felt the shaking.

"My students, colleagues, and I all noticed it and immediately assumed it was an earthquake," N-N teacher Sean Ellison said in an email.
