Tonga volcano eruption was one of the strongest EVER recorded: Scientists believe it was equivalent of up to 30m tons of TNT exploding – making it stronger than Mount St Helens blast.

Is Tonga eruption bigger than Mt St Helens?
The Hunga signal amplitudes are over an order of magnitude larger than those generated by the 1980 Mount St. Helens eruption. The group’s findings were published in the journal Science, on May 12, 2022.
How big was the volcano that erupted by Tonga?
The Jan. 15 eruption came from a volcano that’s more than 12 miles wide, with a caldera sitting roughly 500 feet below sea level. One day earlier, Tongan officials reported the volcano was in a continuous eruption, sending a 3-mile-wide plume of steam and ash into the sky.
Was Tonga eruption louder than Krakatoa?
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.
Was Tonga worse than Krakatoa?
The volcanic eruption on an island near Tonga in January was as powerful as the 1883 Krakatoa eruption in Indonesia, one of the deadliest and most destructive volcanic events on record.
What was the biggest volcanic explosion ever?
Hundreds of articles have been written about the largest volcanic eruption in recorded history, at Indonesia’s Mt. Tambora just over 200 years ago…
What is the largest volcanic eruption in history?
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. Fortunately, these eruptions are rare: they occur every 50,000 or 100,000 years.
How strong is Tonga eruption?
“The eruption was equivalent to around 61 Mt of TNT, whereas the Tsar Bomba released between 50-58 Mt. The Tonga volcanic eruption released energy equivalent to a magnitude 8.4 earthquake, and the pressure wave travelled several times around the globe.
How fast was the Tonga eruption?
Their results suggest that the atmospheric waves produced by the volcano lapped Earth at least six times and reached speeds up to 1,050 feet (320 meters) per second. “The eruption was an amazing natural experiment,” Wright said.
How much co2 did the Tonga volcano emit?
After the Tonga volcano erupted in January 2022, carbon dioxide (CO2) concentrations near the volcano soared to around 414 parts per million (ppm), according to researchers . Compared with estimated 412 ppm had the volcano not erupted, the increased 2ppm equaled a whole year’s CO2 emission on earth.
What is the loudest noise heard on Earth?
But what about the loudest sound ever heard? 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).
Why is 194 dB 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.
How big was the Tonga eruption compared?
Some have compared the Tonga eruption as similar to Krakatoa, and NASA has said the Tonga explosion was at least 500 times more powerful than the bomb dropped on Hiroshima in 1945.
Has Tonga ever been conquered?
The arrival of the Wesleyan missionaries on Lifuka in the 1820s coincided with the rise of Taufa’ahau, a powerful chief who converted to Christianity in 1831. With their help, he won a series of domestic wars. By 1845, he had conquered all of Tonga and declared himself to be the new Tui Tonga.
How powerful was Mt St Helens?
The eruption produced a force equal to 10–50 megatons of TNT, the equivalent of 25,000 atomic bombs released over the city of Hiroshima during World War II, and superheated gas and rock exploded out of the volcano sideways at speeds of up to 400 mph.
How far was Tonga from the eruption?
The eruption, which happened just 65 kilometres from the Tongan capital of Nuku’alofa, has been a disaster for the more than 100,000 people living in Tonga.
What are the 3 largest volcanic eruptions?
The top five biggest volcanic eruptions
- 1 – Mount Tambora.
- 2 – Mount Krakatoa.
- 3 – Mount Pelée.
