“Mother Nature’s Fireworks Respect”
“Space rock violently shattered, creating a pressure wave that shook buildings and made the sound heard by those near the path,” NASA said. “This pressure wave will cause small ‘tremors’ that can be recorded on the ground couple and seismic instruments.”
From infrared measurements of low frequency sounds that can travel long distances, NASA was able to measure the fireball, which weighed about 10 pounds (4.5 kg) and was about six inches (15 centimeters) in diameter.
The company described it as “Mother Nature’s fireworks display honor”.
