How was Anak Krakatoa formed
Anak Krakatoa (Indonesian: Anak Krakatau) is a volcanic island in Indonesia. On 29 December 1927, Anak Krakatoa first emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa.
How loud was Krakatoa
The pressure wave generated by the colossal third explosion radiated out from Krakatoa at 1,086 km/h (675 mph). The eruption is estimated to have reached 180 dB, loud enough to be heard 5,000 kilometres (3,100 mi) away.
Did Krakatoa erupt in 535 AD
The eruption is now thought to have occurred in the interval AD 667–699 based on wiggle-match radiocarbon dating. David Keys suggested the volcano Krakatoa by shifting a cataclysm in AD 416 recorded in Javanese Book of Kings to AD 535.
What does 155 dB sound like
120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off.
How loud was Tsar Bomba
The noise from the largest detonated atomic bomb, the RDS-202 Tsar Bomb, can be estimated at an incredible 224 dB.
Was there a dark age in 536 AD
But in 536 A.D., much of the world went dark for a full 18 months, as a mysterious fog rolled over Europe, the Middle East and parts of Asia. The fog blocked the sun during the day, causing temperatures to drop, crops to fail and people to die. It was, you might say, the literal Dark Age.
How loud is 117 decibels
Levels and sources of damaging noise include: 85 – 100 decibels: For example, a hair dryer, blender, power lawn mower, forklift, or subway train. 100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle. 120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail.
How loud is 310 dB
Deciding decibels
So, at 310dB, the eruption would have been over two times the level that causes pain. As such, anyone close to the eruption would have suffered damage to their organs, and possibly even died. For additional context, only 150-160dB is needed to rupture your eardrums.
How loud is 5000 decibels
5,000dB is louder than a supernova, it can't possibly occur on Earth. If it did happen, it would disintegrate the solar system turning every living thing and rock into disassociated plasma cloud.
What is the loudest noise ever
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away. 3.
Was 1200 BC 1st a dark age
The Greek Dark Age is a period in Greek history that lasted from about 1200 BC to 750 BC. During this time, the various Greek city-states underwent major cultural, political and military shifts. The period is known as the Greek 'Dark Age' because very little written evidence survives from this time.
Was 1200 BC the Dark Ages
The time period known as the Greek Dark Age began in 1200 BCE and lasted until 800 BCE at the start of the Archaic Period. This period of time is associated with archeological evidence such as graves and pottery, which showed a decline in the wealth, art, writing, and culture associated with Bronze Age civilizations.
How bad is 310 decibels
Deciding decibels
So, at 310dB, the eruption would have been over two times the level that causes pain. As such, anyone close to the eruption would have suffered damage to their organs, and possibly even died. For additional context, only 150-160dB is needed to rupture your eardrums.
How strong is 1100 decibels
With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn't 2 times more powerful than 10 decibels, it's 10 times more powerful.
Why is 194dB the loudest sound possible
At 194 dB, the energy in the sound waves starts distorting and they create a complete vacuum between themselves. The sound is no longer moving through the air, but is in fact pushing the air along with it, forming a pressurized wall of moving air.
Is 1100 decibels Loud
It's a ridiculously loud "sound". It's not possible as a continuous sound in air because the maximum overpressure is double atmospheric, with the troughs a vacuum, which works out at 194 decibels.
Can humans hear 1000 decibels
Humans can hear decibel levels between 0 dB (the hearing threshold) and 130 dB (the pain threshold) and sound frequencies between 20 Hz and 20,000 Hz or 20 kHz. Sounds under 20 Hz are known as infrasounds and sounds above 20 kHz are known as ultrasounds.
What was 3000 BC like
The Bronze Age began in the Ancient Near East roughly between 3000 BC and 2500 BC. The previous millennium had seen the emergence of advanced, urbanized civilizations, new bronze metallurgy extending the productivity of agricultural work, and highly developed ways of communication in the form of writing.
What happened in 1100 BC
1100 BC—The Dorians invade Ancient Greece. c. 1100 BC—Mycenaean era ends with the destruction of that civilization. The collapse of Mycenaean dominance starts.
Why is 194 dB the loudest sound possible
A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB, the waves are creating a complete vacuum between themselves. You can go louder than 194 dB, but that's not technically a "sound" anymore.
Is 300db possible
How loud is 300db It's a ridiculously loud "sound". It's not possible as a continuous sound in air because the maximum overpressure is double atmospheric, with the troughs a vacuum, which works out at 194 decibels.
How loud is 10,000 decibels
In terms of sound in earth's atmosphere, anything over 194 dB is a shock wave. 10,000 dB would equate to an overpressure of very nearly 5 x 10^499 atmospheres – quite sufficient I imagine to destroy the earth; though what you would use to create such a shock wave defies imagination.
What could create 1100 dB
so to get 1100 dB, you need to explode 1*10^85 atomic bombs or 1 with 85 zeros on the right.
Can 1100 decibels destroy the universe
Converting the energy of 1,100 decibels to mass yields 1.113×1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila! No more universe.
How loud is 1000db
This puts it quite nicely; the power required to make a 1000 decibel noise for one second is equivalent to the power of the entire sun for 4 billion years (actually I should have said the energy required is greater than that available in the observable Universe).
