Scientists are struggling to monitor an active volcano that erupted off the South Pacific island of Tonga at the weekend, after the explosion destroyed its sea-level crater and drowned its mass, obscuring it from satellites.
The eruption of Hunga-Tonga-Hunga-Ha’apai volcano, which sits on the seismically active Pacific Ring of Fire, sent tsunami waves across the Pacific Ocean and was heard some 2,300 kms (1,430 miles) away in New Zealand.
“The concern at the moment is how little information we have and that’s scary,” said Janine Krippner, a New Zealand-based volcanologist with the Smithsonian Global Volcanism Program.
“When the vent is below water, nothing can tell us what will happen next.”
Krippner said on-site instruments were likely destroyed in the eruption and the volcanology community was pooling together the best available data and expertise to review the explosion and predict anticipated future activity.
Saturday’s eruption was so powerful that space satellites captured not only huge clouds of ash but also an atmospheric shockwave that radiated out from the volcano at close to the speed of sound.
Photographs and videos showed grey ash clouds billowing over the South Pacific and meter-high waves surging onto the coast of Tonga.
There are no official reports of injuries or deaths in Tonga yet but internet and telephone communications are extremely limited and outlying coastal areas remain cut off.
Experts said the volcano, which last erupted in 2014, had been puffing away for about a month before rising magma, superheated to around 1,000 degrees Celsius, met with 20-degree seawater on Saturday, causing an instantaneous and massive explosion.
The unusual “astounding” speed and force of the eruption indicated a greater force at play than simply magma meeting water, scientists said.
As the superheated magma rose quickly and met the cool seawater, so did a huge volume of volcanic gases, intensifying the explosion, said Raymond Cas, a professor of volcanology at Australia’s Monash University.
Some volcanologists are likening the eruption to the 1991 Pinatubo eruption in the Philippines, the second-largest volcanic eruption of the 20th century, which killed around 800 people.
The Tonga Geological Services agency, which was monitoring the volcano, was unreachable on Monday. Most communications to Tonga have been cut after the main undersea communications cable lost power.
American meteorologist, Chris Vagasky, studied lightning around the volcano and found it increasing to about 30,000 strikes in the days leading up to the eruption. On the day of the eruption, he detected 400,000 lightning events in just three hours, which comes down to 100 lightning events per second.
That compared with 8,000 strikes per hour during the Anak Krakatau eruption in 2018, caused part of the crater to collapse into the Sunda Strait and send a tsunami crashing into western Java, which killed hundreds of people.
Cas said it is difficult to predict follow-up activity and that the volcano’s vents could continue to release gases and other material for weeks or months.
“It wouldn’t be unusual to get a few more eruptions, though maybe not as big as Saturday,” he said. “Once the volcano is de-gassed, it will settle down.”
Meanwhile, new powerful eruption A second major eruption has been detected at the Hunga Tonga volcano on Monday, according to an alert from Australia’s Darwin Volcanic Ash Advisory Centre.
The Pacific Tsunami Warning Centre also warned of large waves in the area and said: “This might be from another explosion of Tonga volcano. There are no known earthquakes of significant size to generate this wave.”
Some say it’s fake and want to cover-up:
There were no casualties reported from the second eruption on Sunday night. However, evacuation measures are underway.
Both very impressive images.
Thanks for posting them.
Sounds like something Biden would say between actual words.
Wow….
That last one is shocking! 😜
⚡⚡⚡⛈️🌩️🌩️🌩️⛈️⛈️
Mark!
WOW! Mother nature..the greatest show on earth.
Strange that the weather patterns did not change.
Evening news said Australian air force was sending observation planes because of communication disruption and lack of information of what was happening on the ground in Tonga
I try to imagine what the early Earth must have been like when the surface was boiling molten rock. Then I’m glad that I wasn’t there!
NorCal, Humboldt, nothing at all. Not like the Japanese one. I check the weather early, early morning and sat pic and saw it, got bug out bag and headed to higher ground. Waited. Nothing at all.
Oh, cripes! Time for a new keyboard! ;-)
The friction affect of the shards that are the particulates emitted in the ash cloud. As that stuff is moving around in the atmosphere it creates static electricity, at some point that electricity is released in the form of a lightning strike.
But we never got footage of the big eruption due to a landfalling typhoon.
That's because we secretly blew up SPECTRE's secret underwater base.

I have nothing profound to say except “Wow!”

What little communication there is there was knocked out....further there is no emergency warning network set up there from what I’ve read. The only reason you had the cables is the IMF and other world entities paid for it.
I alos understand there are 30 to 40 underground volcanoes in that area.....which were discovered about 20 yrs. ago.
You were remember?
You were just some amino acid slobber like vomit slick floating about...near the brackish surface ....pining for the day you opine here...after you achieved single cell structure and eventually fins then legs
Just like the rest of us..
Wow. 🥺
