Volcano eruption in Tonga was a once-in-a-millennium event

Mega-eruptions have occurred on Hunga Tonga-Hunga Ha'apai volcano in AD 200 and 1100, suggesting they occur roughly once every 1000 years

Mega-eruptions have occurred on Hunga Tonga -Hunga Ha'apai volcano in AD 200 and 1100, suggesting they occur roughly once every 1000 years

The underwater Hunga Tonga -Hunga Ha'apai eruption has already triggered a tsunami, a sonic boom and thousands of lightning bolts, and could now lead to acid rain

Cronin and his research team camped on Hunga Tonga-Hunga Ha’apai in 2015 and noticed that the surrounding coral reef was lifting up, suggesting that magma was building underneath the volcano and could cause an eruption in the near future.Several small eruptions have occurred in the intervening years, probably as some of the growing pressure forced its way out of small fractures around the edge of the volcano, says Cronin. As the pressure built up further, it led to the breaking point on 15 January that caused the central part of the volcano to blow out, he says.

sounds more like less-roughly 900, but ... anyhow c. 200, c.1100, 2022. That's every 900 years to be pedantic about it. 200, 1100, 2022. 'Roughly' 1000 years, but very near exactly 900? If such a periodical exists you should of consulted New Mathematician. Or any year 4 student. No one go looking for any other once-in-a-millenium events, okay? The universe is watching this year.

maybe we will get some cooling Of course Koreans Testing missiles, side effects show all results. Isn’t it more like every 900? Math! Have a mercy please release promising successful treatment available for spinal cord complete injury we wanna go for a long walk please we are begging for treatment available for us

That's a pretty small sample to come to any conclusion Was there advanced warning for this once in 10 lifetimes event? 900*

Hunga Tonga volcanic eruption was largest in 3 decadesThe Hunga Tonga ha’apai volcanic eruption that occurred Friday evening sent pressure waves around the world, multiple times. The Hunga Tonga undersea volcanic eruption was the largest on earth over the last 30 years, according to Research Physical Scientist Brian Brettschneider with the National Weather Service Alaska region.

Sounds like roughly every 900 years to me, Mr Scientist Linear extrapolation is pathetic, lol nothing is linear in nature 😂 no ..after shocks recorded That proves that The earth is a clock. Since it's 7 Billion yrs old that volcano is erupting once every minute on a billion yr clock and time frame like old faithful in Yellowstone.

there was quite a big eruption there in 2014 which formed a new land mass. we sailed there & explored it. Here's our drone video of what it looked like before this most recent eruption (which may have blown it all away) From two data points? That’s quite a conclusion. Wouldn’t it suggest that it’s a once every 900 years event? 😉

Finally a mega eruption occurs, and the whole world didn't even explode..? I'm disappointed How do you know that one occurred 200AD ?

Tsunami threat recedes after undersea volcano erupts near TongaA tsunami advisory has been issued for the entire west coast of the U.S. after an undersea volcano erupted in spectacular fashion near the Pacific nation of Tonga . Lol on to natural disasters

it heralds the beginning of the Fall of Rome in 200, and the death of Henry V. Three data points! You can't hang your hat on that. We hope the recurrence will not be true for the Vesuvio vulcan... I’m going to need more than two points on my graph JMA_kishou Whoa cool video!

Concerns mount for Tonga after tsunami triggered by underwater volcanoPacific nations and humanitarian groups struggled to establish communications with Tonga on Sunday after a tsunami triggered by a massive volcanic eruption cut telephone and internet connections, raising concerns for the tiny island nation.

Volcano eruption near Tonga causes booms heard by Alaskans nearly 6,000 miles awayMany Alaskans heard the booming sounds early Saturday morning caused by the volcano eruption near Tonga . Hearing a volcano, or any sound, so far away from its origin “is a pretty rare phenomenon,” says an Alaska Volcano Observatory scientist: When Krakatoa erupted you could apparently hear the shock waves not only the first time but the second time they went around.

Eruption of Undersea Volcano Near Tonga Triggers Tsunami Warnings Across PacificThe extent of the damage in the country of Tonga remains unclear. Hawaii and the West Coast experienced effects of the tsunami on Saturday morning.

January 15, 2022 Cronin and his research team camped on Hunga Tonga-Hunga Ha’apai in 2015 and noticed that the surrounding coral reef was lifting up, suggesting that magma was building underneath the volcano and could cause an eruption in the near future. Several small eruptions have occurred in the intervening years, probably as some of the growing pressure forced its way out of small fractures around the edge of the volcano, says Cronin. As the pressure built up further, it led to the breaking point on 15 January that caused the central part of the volcano to blow out, he says. Satellite images show that that the above-water portion of the volcano is now almost completely obliterated. “You wouldn’t be able to camp on it now,” says Cronin. His team found evidence of two previous mega-eruptions occurring on Hunga Tonga-Hunga Ha’apai in AD 1100 and AD 200, suggesting they occur roughly once every 1000 years. The volcano has continued to erupt at a low level since 15 January and Cronin says he “wouldn’t be surprised if there were a few more explosive events” in the coming days or weeks. However, they are unlikely to be as powerful as the initial explosion, he says. More on these topics:
