Disasters "Big Bang in Asia" -
the whole world shakes:
The event makes all the barometer in London up to 7 times higher shock and the whole world shakes in minutes.
Krakatoa is an active volcano on the Ring Fire Pacific. It formed an archipelago system consists of four main islands in Indonesia's Sunda Strait, between Sumatra and Java islands.
"The Big Bang" on 27 August 1883, is one of the worst disasters of human history. It has claimed the lives of 36,417 people and destroyed entire 165 villages and cities, 132 villages were damaged seriously, affecting many areas of the world.
Turn the event "Big Bang explosion of Krakatoa":
Map of the Krakatoa island before it erupted on 27 Aug. |
Krakatoa volcanic erupted most in two days 26 and 27 August. Although in May, it began having eruption signs. The first explosion occurred at 17 hours 07 minutes (local time) on 26 August. Shortly thereafter, a series of eruptions with lower intensity occurred repeatedly, averaging 10 minutes there is an eruption of lava, but no major devastating.
The second and the third eruption occurred at 5 hours 30 minutes and 6 hours 44 minutes (local time) on 27 August. And up to 10 hours 02 minutes, the fourth explosion has created a tsunami with tremendous destructive power. Within an hour later, the wave height reaches at peak 37m, destroying hundreds of villages and towns. And up to 10 hours 52 minutes, much smaller explosion created the swirling cone with the large waves on the sea. The final collapse of the "wall" Krakatoa took place several hours later, at 16 hours 38 minutes.

The sound of the explosion reached 180 dB at a distance of 160 km. Anyone with a distance of 20km have been subjected to noise levels 200dB, while the maximum limit of our hearing is 115dB. The disaster’s shocks can be felt in the city of Perth, Australia - far from it to 3,110 km and even in Maurice Rodriges island - away from disaster 5,000 km.
Even, it also makes all of the barometer (instruments used to measure atmospheric pressure) in London on 7 times higher shock and shake the world in minutes.
With index eruption at level 6, this volcano's explosive force equivalent to 200 megatons, more than 13,000 times of the atomic bomb Little Boy (13 to 16 kiloton) that is thrown into Hiroshima in August 1945. This eruption made the rocks, ash and pumice shot 25 miles away.
Estimates of the last eruption, pumice ejected volume is as high as about 34 to 50 miles in the sky (54 to 80km). The amount of dust stretching to 3,000 miles (4,828 km) in 10 days later, the whole earth surrounded by clusters of dust explosions. Sulfur in ash reacts with atmospheric ozone causes vivid sunsets around the world. The temperature dropped and the global climate disruption lasted five years.
