Tonga eruption could offer clues on planet formation

The life cycle of a volcano off Tonga and the blast generated from its eruption could offer valuable clues about the formation of other planets

The massive volcanic blast which rocked Tonga last week sent out shockwaves close to the speed of sound and tsunami waves across the Pacific Ocean.

And now one NASA expert says it could also provide valuable clues about the formation of other planets.

“I got a call and they said ‘It blew, you don’t have an island anymore.'”

NASA’s chief scientist, James Garvin

Now they’re examining what’s left of the islands, Hunga Tonga and Hunga Ha’apai.

“We took that volume of mass ejected and the energetics to explosively fragment it, and calculated using fairly classical techniques, how much energy that would take, to break a rock that you could build a city building on, to break it up into little bits and throw it as ash and steam up to hundreds of thousands of feet…”

“And so we did that calculation and we got numbers that range from something equivalent to the blast of a small asteroid that would hit the earth – about 10 metric, megatons of TNT or equivalent – to things even bigger.”

NASA’s chief scientist, James Garvin

The Hunga-Tonga-Hunga-Ha’apai volcano sits on the seismically active Pacific Ring of Fire.

The eruption on January 15 was so powerful that it could be heard over a thousand miles away, and huge clouds of ash could be seen from space.

Studying the impact of these volcanoes on Earth tells experts what they may have done to other planets.

“It’s a fossil record of landscapes preserved in time on earth, better preserved on planets like Mars and the moon and Venus. So we use earth as our training ground to project what we know from places like this to other planets that might have oceans, that might have volcanos, that erupt under water.”

Many in Tonga are still reeling from the physical and psychological trauma of last week’s blast, as relief aid continues to pour in.

Australia’s multimillion-dollar campaign to attract Hollywood productions to its shores appears to be paying off.

The allure of Australia lies not only in its picturesque locations but also in its competitive financial incentives.

The government offers generous rebates and tax breaks to international productions, making it an attractive proposition for filmmakers looking to maximise their budgets.

Despite the recent intake of Hollywood productions down under such as ‘The Fall Guy’ and ‘Furiosa: A Mad Max Saga’, Aussie independents are still finding the space to carve their own creative path.

Rob Fantozzi joined the program to discuss the latest in Hollywood, and showcased his own upcoming project – ‘Omerta‘. #featured

American home prices are rising at faster pace now than in the last 20-years.

A recent analysis reveals a jaw dropping surge in the cost of American homes.

Since the start of 2020, U.S. home prices have surged 47% easily outstripping the gains seen in recent decades.

On top of that, home price growth so far this decade is on the verge of surpassing all the growth seen in the 2000s.

Many experts believe this decade’s housing market frenzy was ignited by a perfect storm — the onset of the COVID-19 pandemic triggering an unprecedented rush among buyers.

Tom Hutchens, the Executive Vice President of Production at Angel Oak Mortgage Solutions joins Veronica Dudo to discuss.
