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

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.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.

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*

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 ?

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!
