Satu lapan lapan tiga
mencret membahana
Ledaknya melanglang bumi tiga kali
baru luruh, berhenti bergelombang
Padahal wibawanya ancala
tapi buang air sekali,
kadal jura terperanjat dalam oli,
batuk-batuk oleh serdak yang berfisi
Kuping yang berdarah, matanya berair
Gelembung udara berangkat
Orang-orang mangkat
Pamit menjadi oli

"The 1883 Krakatoa volcano eruption: I'm overwhelmed by the amount of things I need to tell you about the Krakatoa. Let's do bullets.-
- Krakatoa is an island in Indonesia, and the eruption happened on August 27, 1883.
- 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.
- But the most amazing thing about the eruption was its sound. It made arguably the loudest sound on Earth in modern history.
- It was so loud that the shock wave extended far enough to rupture the eardrums of sailors 40 miles away.
- 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.
- The sound cracked a foot-thick concrete wall 300 miles (483 km) away.
- 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.
- Finally, you know the famous painting ? 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.
It was a big eruption."
