How much explosive force did the Krakatoa eruption of 1883 have?
200 megatons
The 1883 Krakatoa eruption measured a 6 on the Volcanic Explosivity Index (VEI), with a force of 200 megatons of TNT. By comparison, the bomb that destroyed the Japanese city of Hiroshima in 1945 had a force of 20 kilotons, or nearly 10,000 times less power.
Why did temperature drop after Krakatoa exploded?
There was a lasting effect on the world’s climate, too: aerosols emitted into the atmosphere by the blast led global air temperatures to drop by as much as 2.2 degrees Fahrenheit (1.2 degrees Celsius).
How was Krakatoa so loud?
In general, sounds are caused not by the end of the world but by fluctuations in air pressure. A barometer at the Batavia gasworks (100 miles away from Krakatoa) registered the ensuing spike in pressure at over 2.5 inches of mercury. That converts to over 172 decibels of sound pressure, an unimaginably loud noise.
What was the most powerful volcanic eruption?
of Mount Tambora
The explosion of Mount Tambora is the largest ever recorded by humans, ranking a 7 (or “super-colossal”) on the Volcanic Explosivity Index, the second-highest rating in the index.
Did Krakatoa cause the year without a summer?
The 1883 eruption of Krakatoa caused average Northern Hemisphere summer temperatures to fall by as much as 1.2 °C (2.2 °F). One of the wettest rainy seasons in recorded history followed in California during 1883–84.
What was the loudest sound ever on earth?
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

Apa itu Gunung Anak Krakatau?
Gambar udara yang diambil pada Agustus 2018 ini menunjukkan Gunung Anak Krakatau sebagai pulau kecil yang diselimuti material vulkanik. Gunung itu berada di tengah lingkaran yang terdiri dari tiga pulau, yang menunjukkan perkiraan lokasi gunung Krakatau semula. Erupsi pada tahun 1883 menyebabkan ambruknya struktur-struktur utama Gunung Krakatau.
