The eruption was 10,000 times more powerful than the atomic bomb

The sound from the volcanic eruption Krakatoa in 1883 is considered to be the largest in the world, can be heard clearly from a location thousands of kilometers away.

The volcano on the island of Krakatoa, located between Java and Sumatra, Indonesia, produced a loud sound during a record eruption on August 27, 1883, according to Science Alert. This sound can be heard within nearly 5,000km in many geographical locations and is considered the largest in history.

People of New Guinea and Western Australia, about 3,200 kilometers from Krakatoa, hear a loud explosion like a northwestern cannon, according to Nautilus. On Rodrigues Island, Indian Ocean, 4,800km farther away, locals report hearing a sound like a gunshot from afar.

The eruption caused the smoke to rise nearly 80km and the ash fell into the sea about 20km away. Shock waves from the eruption circled the world several times. Hot matter fires from Krakatoa crater at speeds of up to 2,575km / h, more than double the speed of sound.

This is considered the biggest natural disaster in the 19th century because the surrounding area suffered severely. The impact of the eruption of a tsunami up to 45m collapsed on the coast on Java and Sumatra islands, severely destroying the coastal area. About 36,000 people were killed in the disaster.

In remote South African waters, boats also wobble due to the impact of large waves. The area less than 100 km away from Krakatoa clearly felt the power of the eruption. Meanwhile, the British ship Norham Castle is operating 64km from Krakatoa.

"A scary explosion. The sound is terrible. I am writing in the dark darkness. The explosion is so intense that it ruins the eardrum of more than half the crew. My last thought is about my beloved wife. I think that the end has come, "the captain of the ship wrote in his travel diary.

The power of the eruption is 10,000 times the atomic bomb dropped on Hiroshima city, Japan, 1945. The recorded sound is about 172 decibels (dB) at a distance of 160km. Meanwhile, 130 dB is the threshold that makes people almost unbearable and the sound of jet engines standing close is only 150 dB.
