The 1883 eruption of Krakatoa


#1

Not sure how many people on here know much about this, but I was reading yesterday some staggering statistics.

Apparently (from Waitbutwhy):

:black_medium_small_square:Krakatoa is an island in Indonesia, and the eruption happened on August 27, 1883.
:black_medium_small_square:The eruption completely annihilated the island, sending an enormous amount of debris 17 miles (27 km) high into the sky at half a mile per second. It also caused one of the most deadly and far-reaching tsunamis in history. In total, the eruption killed 36,000 people.
:black_medium_small_square:But the most amazing thing about the eruption was its sound. It made arguably the loudest sound on Earth in modern history.
:black_medium_small_square:It was so loud that the shock wave extended far enough to rupture the eardrums of sailors 40 miles away.
:black_medium_small_square:100 miles away, the sound was still 172 dB, enough to permanently destroy someone’s ears or even kill them. Wherever you are, think of a place that’s about 100 miles (161 km) away. Now imagine something happening there that causes a sound so loud where you are that if you were screaming at the top of your lungs directly into someone’s ear when the sound hit, they wouldn’t be able to hear that you were doing it. For comparison, the Saturn V launch sound was at 170 dB 100 meters away. Krakatoa was higher than that 100 miles away.
:black_medium_small_square:The sound cracked a foot-thick concrete wall 300 miles (483 km) away.
:black_medium_small_square:The sound was heard all the way in Australia (where it sounded like a distant canon ball being fired) and even as far away as Rodrigues Island, 3,000 miles away. 3,000 miles away. I’m currently in New York. Imagine if something happened in California or in Europe that I could hear in New York. I can’t even.
:black_medium_small_square:After the sound eventually got far enough away that humans couldn’t hear it anymore, barometers all over the world were going nuts for the next few days, as the sound waves circled the Earth 3.5 times.
:black_medium_small_square:Finally, you know the famous painting The Scream? Well you know how the sky’s all red for some reason? The sky is red because the painter, Edvard Munch, was inspired to paint it after seeing the Krakatoa-caused red skies all over the Western Hemisphere in the year after the eruption.

Put that in your pipe and smoke it.

The Wikipedia page is interesting too.

I barely know 'er!


#3

was listening to something on the radio the other night and apparently the correct pronunciation of Krakatoa is Krak-a-taw

who knew! was always a oa man myself


#4

Named after the noise it made while exploding


#5

I thought this was going to be about Kasabian.


#6

Last fact’s a bit shit, otherwise excellent, thank you.


#7

Thinly veiled I’m in NY post


#8

This statement has obviously no longer been true since Kasabian’s 2014 Glastonbury headlining performance.

#10

Krakatoa. Likely to miss this weekend’s trip to Exeter City.


#11

I was there, man.


#12

Read this first as Kasabian, didn’t realise they were blowing the roof off all the way back then!


#13

Kasabian

I was only talking about Krakatoa with my little bro just yesterday, we’d seen it on some programme or podcast and he asked a million questions. Trying to think what were were watching / listening to now…

Enjoy reading about a good volcanic eruption. Interesting that the Wikipedia page doesn’t have a note of the effects of the climate change on crop productions for the subsequent years - apparently 1.2c temperature change led to mass starvation in many areas. Something that should resonate when global climate change accords seem hung up on the no more than 2c change target.

Pre-history, but Lake Toba was pretty impressive too in the fact that it killed most of the world’s human population at the time:


#16

A similar eruption wiped out the Minoan civilisation. There’s a fairly convincing theory that’s where the story of Atlantis came from. Advanced and mysterious island civilisation wiped out in a natural disaster and all.:


#17

It’s terrifying how ill-equipped humans are to cope with (and even survive) big volcanic eruptions.


#18

Yellowstone’s going to be pretty special.

That one under Yosemite is a bit scary…

As is Mount Teide in Tenerife…

:notes::musical_note: Happy Thursday everyone :musical_note::notes:
