Krakatoa is said to have created the loudest sound ever produced on the planet's surface—at least in human history. The Krakatoa volcano exploded with unimaginable might, generating sound vibrations audible hundreds of kilometres distant. The Krakatoa explosion was arguably the most audible sound ever heard by human ears. Pheb 6th, 2020.
The strength of this explosion was such that it is estimated to have been capable of shaking the Earth with more energy than all other causes combined. All other causes except one: the impact of a giant comet. A huge volcanic eruption isn't the only way to create a loud noise. When objects with mass hit each other at high speeds they can generate much louder sounds than an eruption or explosion. Such impacts have been identified as the source of many past events believed by scientists to have created the world's earliest civilizations.
The biggest threat we face from asteroids is not their impact but the fire they could start if they were to enter our atmosphere. An asteroid or comet with a small enough diameter to burn up in the atmosphere before causing damage on ground level would be called a meteorite. Meteors are one of the most common forms of pollution found in Earth's atmosphere and the cause of many accidents during which people see lights in the sky before being killed by falling objects.
A large meteorite can do serious damage when it hits the ground. One such incident occurred in Russia about 65 million years ago.
Not only did the Krakatoa eruption in 1883 inflict significant devastation to the island, but it also produced the loudest sound ever recorded at 180 dB. It was so loud that it could be heard 3,000 miles (5,000 kilometers) distant. 3.9 million people died as a result of the tsunami that followed.
The impact sound wave produced by an earthquake is called an "earthquake signal." The intensity of this signal is dependent on many factors such as the size and type of fault that ruptured, the distance from the source area of the quake to the surface of the earth, and the physical properties of the rock through which the signal must pass before reaching the surface. Large earthquakes far away from any major landmasses or islands usually cause tsunami's that are too small to be detected by most sensors. These tsunamis were likely caused by large cracks forming in Earth's crust with water pouring into the resulting voids - similar to how a bathtub drains when you put your hand inside.
The Krakatoa volcano is located on an island in the Sunda Strait between Java and Sumatra countries. In 1883, there was a series of explosions that led to the formation of a new island. The volume of material ejected by Krakatoa during its most explosive phase was estimated to be equivalent to about twenty million tons of TNT. This makes it the largest known volcanic explosion in history.
3-4 minutes long.
The explosion was so powerful that it collapsed part of the mountain into a massive crater that was 30 km across and 300 m deep. Total energy released by the eruption may have been as much as 10 million megatons, more than half the total energy of all other volcanoes combined.
The collapse of this single volcano caused global temperatures to drop by 0.8 degrees Celsius for several years following the eruption. It is estimated that no less than 5% of all species on Earth were destroyed at the time or since. The death toll from the eruption has never been accurately determined, but it's likely in the tens of thousands.
The biggest threat of volcanic eruptions not only to humans but also to animals is the gas they emit. If you live in an area where there are any signs of activity and the air doesn't smell like sulfur dioxide, then go outside and take a few breaths. If you can still see your footprints in the snow then the gas has not reached dangerous levels yet. Otherwise, find somewhere safe and stay there until it does.
This is equivalent to being inside a large room when someone flips a switch and all lights come on.
Decibels are a unit used to measure pressure waves. In general, the louder the noise, the higher its decibel rating. But just because something is loud does not mean it's dangerous. For example, noises between 100 and 120 dB are commonly heard around airports and train stations. While anything above 140 dB is dangerous to human hearing.
The Krakatoa eruption was so loud that it was detected thousands of miles away in Europe. Scientists now believe this event may have triggered a series of underwater landslides called flukes that extended for hundreds of miles.
The biggest danger from loud sounds is damage to ears caused by prolonged exposure to levels above 80 dB. Hearing loss is also risk if you expose your ears to high-decibel noises such as those from firearms or heavy machinery.
3. A 1-ton TNT bomb: The detonation from this bomb would be 210 decibels. It was more than enough to rupture eardrums of anyone within a 20-mile (30-kilometer) radius.
The Yellowstone National Park supervolcano is one of the most dangerous volcanoes in the world. It has been estimated to have the potential to kill up to 50 million people if it erupted today. However, scientists believe that its last major eruption was about 640 AD and since then it has been in a state of "semi-silence."
The volcano's last major eruption sent lava flows as far as 10 miles (16 kilometers) from the main vent and covered much of central Wyoming in several hundred feet of hardened lava.
During World War II, Axis bombers used the nuclear explosion at Bikini Atoll to calibrate their own nuclear weapons. The tests generated a large number of radioactive particles that were carried by winds across the Pacific Ocean to reach North America. One such particle lodged in an oak tree near Carlsbad, California, causing a radiation leak that exposed local residents to harmful levels of gamma radiation for several days. Another particle was found in Tokyo after the war had ended.
This is more than enough power to blow out a candle if you were close by.
The explosion was so loud that it was heard around the world. The wave it caused killed between 50,000 and 100,000 people. It is considered one of the most destructive natural disasters in history.
Loud noises are not usually harmful, but there are times when they do cause damage. When explosions such as these happen near or over populated areas they can cause death and damage to property.
Some people may be prone to hearing loss due to exposure to loud noises. This could be because they have damaged hair cells in their ears or a family history of hearing problems. If this happens to you, try not to expose yourself to too much noise or change your habits. See a doctor if this problem persists for longer than two weeks.
The military uses large explosions as part of its tactics on land and sea. Some of these explosions are very dangerous and cause damage to buildings within range of the sound. Others are used to create distraction while others still are designed to scare away animals or humans.
