What is the loudest volcano 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.
On the morning of 27 August 1883, on the Indonesian island of Krakatoa, a volcanic eruption produced what scientists believe to be the loudest sound produced on the surface of the planet, estimated at 310 decibels (dB).
On August 27, 1883, a sound emerged from the Earth louder than anything recorded before — or since. The volcanic eruption bellowed out from Krakatau, an uninhabited island between Java and Sumatra in Indonesia.
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.
| Eruption | Year | Casualties |
|---|---|---|
| Mount St. Helens, Washington | 1980 | 573 |
| Kilauea, Hawaii | 1924 | 11 |
| Lassen Peak, California | 1915 | 04 |
| Mount Vesuvius, Italy | 79 A.D. | 3,3602 |
Very hot!! Here are some temperatures recorded at different times and locations: The eruption temperature of Kīlauea lava is about 1,170 degrees Celsius (2,140 degrees Fahrenheit). The temperature of the lava in the tubes is about 1,250 degrees Celsius (2,200 degrees Fahrenheit).
Mauna Loa, which means "long mountain" in Hawaiian, is the largest active volcano in the world. It covers 2,035 sq miles (5,271 sq km), and is one of a chain of five volcanoes which form Hawaii's Big Island.
The most violent eruption registered in history was that in the La Garita Caldera in the United States. It occurred 2.1 million years ago and formed a 35 x 75 km crater, drastically changing the climate on Earth.
Taupo erupted 22,600 years ago and is the most recent supereruption on Earth (with a volume of about 1,130 cubic kilometers). Additional volcanoes capable of producing supereruptions include the large caldera volcanoes of Japan, Indonesia, and South America.
Mt. Kilauea in Hawaii erupts quietly, producing low-viscosity lava flows.
Is there a volcano under the Earth?
Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.” Although most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth's volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.
Volcanic eruptions play an important role in cooling the planet. The sulphur gases from the volcanic plumes combine with other gases in the atmosphere, and these aerosols scatter solar radiation, reflecting it into space.
Sounds above 150 dB have the potential of causing life-threatening issues. Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs. As for exploding heads, you can expect that from sounds above 240 dB.
a sound greater than 1,100 decibels would unleash enough energy to act like an equivalent quantity of mass. Through Einstein's laws of relativity, this mass would create enough gravity enough to form a black hole. Shortly thereafter, everything in existence would disappear in a crush of sound.
Apparently, a sound of 1,100 decibels would create so much energy, it would act as a immensely high quantity of mass. This would, in turn, create enough gravity to form an extremely large black hole!
That's what scientists can offer when talking about the giant super volcano under Yellowstone National Park. The bad news is that the super volcano will erupt and will likely destroy much of the United States.
Although another catastrophic eruption at Yellowstone is possible, scientists are not convinced that one will ever happen. The rhyolite magma chamber beneath Yellowstone is only 5-15% molten (the rest is solidified but still hot), so it is unclear if there is even enough magma beneath the caldera to feed an eruption.
Mauna Loa erupted most recently in 1984, and will erupt again in the future, posing significant risks to people living on the flanks of the volcano.
Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life.
The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond. But the twist is that at atmospheric pressure, it is almost impossible to melt diamond as its burning point is 900 °C (1173 K).
What doesn't melt in lava?
The short answer is that while lava is hot, it's not hot enough to melt the rocks on the side of or surrounding the volcano. Most rocks have melting points higher than 700℃.
The United States is home to three active supervolcanoes, the USGS has determined: The famous Yellowstone, Long Valley and the Valles Caldera in New Mexico.
It's called the La Garita Caldera, and it rivals the Toba eruption in Indonesia and all Yellowstone eruptions. These are “supervolcanoes,” so comparing them to Italy's Vesuvius or Washington's Mount St. Helens is like comparing blowing out birthday candles to a hurricane.
The Yellowstone supervolcano last erupted about 640,000 years ago. A sleeping giant is nestled in the western part of the United States. Though it stirs occasionally, it has not risen from slumber in nearly 70,000 years.
Answer and Explanation: Mount Etna in Sicily, Italy is thought to be the oldest active volcano. It first erupted in the year 1500 BC and since then, it has erupted close to 200 times. It is also one of the largest known volcanos in the world.
The most recent volcanic activity at Yellowstone consisted of rhyolitic lava flows that erupted approximately 70,000 years ago. The largest of these flows formed the Pitchstone Plateau in southwestern Yellowstone National Park.
No, Mount Everest is not a volcano. It was produced from a tectonic collision between the Indian and Eurasian tectonic plates tens of millions of years ago.
"There are about 169 volcanoes in the United States that scientists consider active. Most of these are located in Alaska, where eruptions occur virtually every year. Others are located throughout the west and in Hawaii (see our Volcano Activity Map for their locations).
Calupin Volcano in New Mexico
This extinct volcano last erupted about 60,000 years ago and it isn't expected to erupt again.
ANSWER: Although it is possible, scientists are not convinced that there will ever be another catastrophic eruption at Yellowstone. Given Yellowstone's past history, the yearly probability of another caldera-forming eruption can be approximated as 1 in 730,000 or 0.00014%.
What is a purple volcano?
The eruption of a remote Russian volcano in June has been tingeing sunrises and sunsets the world over a gorgeous purple hue. According to researchers at the University of Colorado, Boulder, the volcano Raikoke spewed sulfur dioxide into the atmosphere, which led to the creation of tiny particles called aerosols.
The coldest erupting lava in the world is the natrocarbonatite lava of the volcano Oldoinyo Lengai, Tanzania that erupts at temperatures of 500-600°C (930-1,110 °F). Common basaltic lavas erupt at temperatures between 1,100 and 1,200°C (2,010-2,190 °F). Oldoinyo Lengai is the only active carbonatite volcano on Earth.
This water vapor then condensed in our atmosphere and fell as rain. It rained for so long that eventually, our dry, barren Earth turned into a Blue Planet. 'Water that we see on Earth mostly comes from volcanoes. Without volcanoes, there wouldn't be life on Earth, literally.
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth.
Lava is indeed very hot, reaching temperatures of 2,200° F or more. But even lava can't hold a candle to the sun! At its surface (called the "photosphere"), the sun's temperature is a whopping 10,000° F! That's about five times hotter than the hottest lava on Earth.
Yes. Human activity can probably cause volcanic eruptions, albeit indirectly. Regardless, human activity affects volcanic disasters in several other ways.
If you want an explosive volcanic eruption, you want to produce bubbles (and lots of them) by (1) decompressing the magma, causing gases to come out of solution; (2) crystallizing minerals to concentrate water/volatiles in the remaining magma or (3) heating the magma with a new intrusion.
A sonic black hole, sometimes called a dumb hole or acoustic black hole, is a phenomenon in which phonons (sound perturbations) are unable to escape from a region of a fluid that is flowing more quickly than the local speed of sound.
A nuclear bomb.
Decibel meters set 250 feet away from test sites peaked at 210 decibels. The sound alone is enough to kill a human being, so if the bomb doesn't kill you, the noise will. Fun fact!
Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears! You should also have found sound levels drop off quickly as you get farther from the source.
How loud is 1000000 decibels?
| Sound | Sound Level (in dB) | Sound Intensity (in pW/m2) |
|---|---|---|
| Conversation | 60 | 1,000,000 |
| Noise inside car | 70 | 10,000,000 |
| Vacuum cleaner | 80 | 100,000,000 |
| Leaf blower | 90 | 1,000,000,000 |
That's a note played at a frequency a million, billion times lower than anything the human ear can detect. And the output is a whopping ten-to-the-power-of-thirty-seven watts, or about ten billion times the energy of our Sun.
There are more than a few popular myths that have permeated the annals of space history, including one that the launch of th Saturn V rocket was so loud that the sound itself melted concrete and set fire to grass more than a mile away. Sadly, as many myths go, that's simply not true.
Sounds above 90 dB can lead to chronic hearing damage if people are exposed to them every day or all the time. Hearing becomes uncomfortable if the sound pressure level is above 110 decibels (threshold of discomfort), and it becomes painful above 130 decibels (threshold of pain).
It may be possible to destroy everything with a loud enough sound. NASA estimates the mass energy of the universe at 4x1069 joules. But that number that is considerably smaller than the energy created by 1,100 decibels of sound.
On the morning of 27 August 1883, on the Indonesian island of Krakatoa, a volcanic eruption produced what scientists believe to be the loudest sound produced on the surface of the planet, estimated at 310 decibels (dB).
The Krakatoa explosion registered 172 decibels at 100 miles from the source. This is so astonishingly loud, that it's inching up against the limits of what we mean by “sound.” By 1883, weather stations in scores of cities across the world were using barometers to track changes in atmospheric pressure.
Pneumonoultramicroscopicsilicovolcanoconiosis is famous for being one of the world's longest words,although factitious. The word means "a lung disease caused by inhalation of very fine silica dust usually found in volcanos".
It was not just the most powerful in this century, it also released atmospheric waves with an energy that has not been seen in 139 years. It was the loudest sound on Earth since the Krakatoa eruption of May 20, 1883.
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 would happen if Yellowstone erupted?
If another large, caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Such a giant eruption would have regional effects such as falling ash and short-term (years to decades) changes to global climate.
Jill Drake, a teaching assistant who in 2000 won the Guinness World Record for the loudest individual's shout – 129 dB.
But the loudest is the sperm whale. It makes a series of clicking noises that can reach as high as 230 db making it the loudest animal in the world. The click lasts for only 15 to 30 milliseconds and can stay audible to a sperm whale as much as 10 miles away.
The Oxford English Dictionary lists pneumonoultramicroscopicsilicovolcanoconiosis as “a factitious word alleged to mean 'a lung disease caused by inhalation of very fine silica dust usually found in volcanos' but occurring chiefly as an instance of a very long word”.
The first records of pneumonoultramicroscopicsilicovolcanoconiosis come from around 1935. According to many sources, it was coined by Everett Smith, who at the time was the president of the National Puzzlers League. Pneumonoultramicroscopicsilicovolcanoconiosis is a New Latin word made up of five parts.
Microsoft's main anechoic chamber has the lowest sound level ever recorded. It is just a few decibels off of the lowest sound theorized by scientists.
Tsar Bomba (224dB)
The Hiroshima and Nagasaki bombs of 1945 destroyed cities in an instant – but the Tsar bomb was 3,300 times stronger than that and is considered the strongest sound every produced by mankind, with the most reliable figure suggesting it clocked at 224dB.
On 18th May 1980, Mount St Helens erupted in Skamania County, Washington. The force was enough to blow down trees 16 miles away and it was seen on the Space Shuttle from outer space. The sound measured 163 decibels and the force blew windows out up to 200 miles away in Seattle!
No, Mount Everest is not a volcano. It was produced from a tectonic collision between the Indian and Eurasian tectonic plates tens of millions of years ago.
Loud explosions, bubbles bursting, rumbling, hissing, and roaring like a jet engine describe some of the sounds heard from volcanoes around the world. Stories of sounds from historical eruptions tell of loud booms and explosions from volcanoes heard thousands of kilometers away.
