Letusan Krakatau 1883: suara paling keras di dunia

The loudest sound ever recorded: Krakatoa 1883

Letusan Krakatau 27 Agustus 1883 terdengar sampai Pulau Rodrigues, hampir 4.800 km jauhnya, dan gelombang tekanannya terekam barometer berkeliling Bumi beberapa kali.

Penjelasannya

Pada 27 Agustus 1883, sebuah gunung api di Indonesia menghasilkan suara paling keras yang pernah tercatat di Bumi. Ketika Krakatau meledakkan dirinya, kekuatan ledakannya diperkirakan sekitar 310 desibel.

Pada kekuatan itu, suara bukan lagi sekadar bunyi, melainkan gelombang kejut udara yang memecahkan gendang telinga hingga sekitar 64 km jauhnya. Orang di Australia tengah mendengarnya seperti tembakan meriam dari jarak lebih dari 3.500 km. Di Pulau Rodrigues dekat Afrika, hampir 4.800 km jauhnya, kepala polisi melaporkan mendengar bunyi meriam kapal di kejauhan.

Gelombang tekanannya begitu dahsyat sampai barograf di London dan New York merekamnya mengelilingi Bumi hampir empat kali. Satu ledakan di Selat Sunda terdengar di sekitar sepertiga belas permukaan Bumi.

Transkrip video (English)

On August 27, 1883, an Indonesian volcano produced the loudest sound ever recorded on planet Earth.

When Krakatoa tore itself apart, the blast was estimated at a deafening three hundred ten decibels.

At that power, it wasn't just sound: it became a physical shockwave of air that ruptured eardrums forty miles away.

People in central Australia heard it like artillery fire over twenty-two hundred miles across the ocean.

On the island of Rodrigues near Africa, nearly three thousand miles away, the chief of police reported hearing distant naval gunfire.

The pressure wave was so violent that barographs across London and New York recorded it circling the entire globe nearly four times.

One explosion in the Sunda Strait, heard across one-thirteenth of the entire surface of the Earth.
