#Insolite et #Effrayant 🌋 Le son de l'Apocalypse : à 310 décibels, le bruit le plus violent de l'Histoire. Si puissant qu'il a percé les tympans de la moitié de l'équipage d'un navire britannique 🇬🇧 à 60 km de distance et fait le tour du globe 🌎 au moins 7 fois.

L'onde sonore a pu être suivie à la trace en observant la pression baromètrique.

Le son de l'Apocalypse : à 310 décibels, le bruit le plus violent de l'Histoire a fait le tour de la Terre

Le 27 août 1883, une catastrophe naturelle en Indonésie a provoqué le bruit le plus puissant de l'histoire de l'humanité. L'onde sonore a fait plusieurs fois le tour de la Terre en perçant des tympans à des dizaines de kilomètres.

🌋 On Aug 27, 1883, Krakatoa erupted with cataclysmic force. The blast was heard 3,000+ miles away, unleashed tsunamis over 30m high, and darkened skies worldwide. Global temperatures dropped, and vivid sunsets inspired artists for years.

@onthisday Perspective: in mid 1800s, world population was about 1.5Bn.

Today, we are sitting at just over 8Bn.

36,417 people then would be about 200k people.

The Sound So Loud That It Circled the Earth Four Times

On 27 August 1883, the Earth let out a noise louder than any it has made since.

Think, for a moment, just how crazy this is. If you’re in Boston and someone tells you that they heard a sound coming from New York City, you’re probably going to give them a funny look. But Boston is a mere 200 miles from New York…

Travelling at the speed of sound (766 miles or 1,233 kilometers per hour), it takes a noise about 4 hours to cover that distance. This is the most distant sound that has ever been heard

If we were not resilient, Earth’s extreme events would have wiped us out long ago. Somehow H. sapiens finds a way, even through something like the VEI 6 eruption of Krakatoa in a busy sea tra…
