Welcome to Brain Pop! — where your brain goes boom with one mind-blowing fact every day!
I’m your host, Fin — and today’s fact is loud, like really loud. So maybe cover your ears and hold onto your headphones, because we’re about to blast off into the world’s biggest BOOM ever recorded.

Let’s get that brain popping — with a BOOM you’ll never forget!

Alright, here it is:
The loudest sound that’s ever been measured on Earth was caused by a volcano — and not just any volcano, but Krakatoa in Indonesia, back in 1883. When it erupted, the explosion was so powerful, it created a sound wave that could be heard over 3,000 miles away — that’s around 4,800 kilometers!

To help you picture that:
•That’s like an explosion in New York being heard all the way in California.
•Or from London, England all the way to Egypt.
•Or from Sydney, Australia to Singapore.

Pretty far, right? And people that far away didn’t just hear a faint rumble — they heard a BOOM so loud, it was like it happened right next to them.

Scientists believe the sound reached around 310 decibels.

But wait — what’s a decibel, and how loud is that?

Here’s a quick sound-o-meter to help:
•A whisper is about 30 decibels.
•A normal conversation is around 60 decibels.
•A dog bark is about 90 decibels.
•A car horn? Around 110 decibels.
•A jet engine taking off? A super loud 140 decibels — and that can hurt your ears if you’re standing nearby!

But Krakatoa’s boom? It was so loud, it ruptured eardrums of sailors over 60 miles away and caused a pressure wave that circled the entire Earth four times.
Some people who were close to the eruption said they didn’t just hear it — they felt it in their chest.

It literally shook the air!

To put it in kid-size terms:
•It was louder than a thousand race cars revving at once.
•Louder than an entire marching band blasting in a small room.
•And louder than if every kid at a birthday party screamed at the same time… next to a volcano.

And get this: the eruption caused a giant tsunami, changed the weather, and even made sunsets look red and purple all around the world for months afterward!

So yeah — the loudest sound wasn’t a rock concert or a rocket. It was Mother Nature saying, “BOOM!”

Wow! — that fact really made my eardrums wiggle!
Thanks for popping your brain with me on today’s explosively awesome episode of Brain Pop!.
