The meteor traveled 33 miles northeast – from Mount Mansfield State Forest to Beach Hill in Orleans County south of Newport.
NASA Meteor Watch said the object was likely a fragment of an asteroid, while the trembling witnesses were caused by a pressure difference between the front and back of the object.
“The space rock shattered violently, creating a blast wave that rocked buildings and made the noise heard by people near the trajectory,” the agency said. “Such a pressure wave can also couple into the ground and cause minor vibrations that can be picked up by seismic instruments in the area.”
Based on infrasound measurements, which are low-frequency sounds that can travel great distances, the agency was able to measure the fireball, weighing about 10 pounds and about six inches in diameter.
The agency called it: “A nice little fireworks display, courtesy of Mother Nature.”
