[00:00:00]There was a sound so powerful it traveled around the entire Earth.

[00:00:06]In 1883, a volcanic eruption produced the loudest sound ever recorded.

[00:00:12]It was heard thousands of kilometers away.

[00:00:15]But that wasn't the strangest part. The shockwave circuit the planet multiple times. Instruments detected it again and again long after the eruption ended.

[00:00:28]Which means for hours the Earth itself was carrying the sound over and over again as if the planet was still reacting to what happened.
