A meteor, the size of a bowling ball, streaked across the Vermont sky in the US on March 7 at a powerful speed of over 67,000 km per hour. NASA Meteor Watch said it was likely a fragment of an asteroid, and reported that the explosion caused slight Earth tremors.
The meteor fragmented violently, rattling buildings and creating a noise that could be heard only by those nearby. The space rock then hit the Earth’s atmosphere, where air resistance created pressure to build-up ahead of the asteroid. NASA stated that the pressure created is what would cause minor tremors in the Earth.
