A meteor broke up in the atmosphere on Saturday afternoon, creating a massive sonic boom heard across the New England region [1, 2].
The event caused widespread alarm as thousands of people reported hearing the explosion and feeling their homes shake [4]. Because the blast was felt from New Hampshire to Rhode Island, it triggered immediate concerns regarding the source of the noise until NASA provided a scientific explanation [3, 5].
NASA confirmed the meteor broke up 40 miles above the Earth [1]. The agency said the energy released during the atmospheric breakup was equal to about 300 tons of TNT [2, 6]. This release of energy generated a sonic boom that resonated across Massachusetts and surrounding states [6].
The explosion occurred around 2:30 p.m. on Saturday [4, 7]. Residents in various locations described the sound as a loud boom, while some reports specifically characterized the event as a "double boom" [5, 8].
Reports of the blast reached across a broad geographic area, including Boston, and other parts of Massachusetts [5, 9]. Some residents reported that the force of the sonic boom was strong enough to shake their entire houses [3].
NASA said the event was the result of a meteoroid entering the atmosphere at high speed and disintegrating. This process converts kinetic energy into heat and pressure, which can result in the powerful acoustic waves experienced on the ground [6].
“The energy released was equal to about 300 tons of TNT, NASA said.”
This event demonstrates the significant atmospheric impact of relatively small meteoroids. While the 300-ton TNT equivalent is substantial, the 40-mile altitude provided a buffer that prevented ground-level damage, turning a potentially destructive impact into a regional acoustic event.
