In this episode, we dive deep (literally) into underwater volcanology with Associate Professor Rebecca Carey, a world-renowned volcanologist and researcher at the University of Tasmania. Co-host Dr Hannah Moore (also one of Rebecca's past PhD students) and host Dr Olly Dove speak with Rebecca about her upcoming 2025 voyage aboard the RV Investigator to Tonga, where she and her team will study the aftermath of the catastrophic 2022 Hunga Tonga-Hunga Ha'apai eruption. The discussion unpacks how underwater eruptions are studied and what new discoveries might await on the seafloor.Show theme music: Kevin MacLeodThank you to the whole TWICS team for the incredible behind-the-scenes volunteering every week!

NASA recently spotted something strange on Mars—a nearly perfect square-shaped formation on the planet's surface! At first glance, it looks like something artificial, sparking wild theories about aliens and ancient civilizations. But scientists believe it's actually a natural geological formation, likely caused by cracks, erosion, or volcanic activity. Nature sometimes creates surprisingly geometric shapes, just like hexagonal basalt columns on Earth. While it's not proof of Martian life, it's still an exciting discovery that makes us wonder what else is hiding on the Red Planet. Who knows? Maybe one day, we'll find something even more mysterious!

Dr Heather Handley joins the podcast to discuss volcanoes both in Australia and abroad. In part 2, we discuss some of the largest historical eruptions, including Hunga Tonga-Hunga Ha'apai eruption from 2022. Do volcanoes emit smoke, and what is the greatest volcano movie of all-time?
Oil sands produce more air pollution than industry's required to report, study says (0:54) The volume of airborne organic carbon pollutants — some of the same pollutants that lead to smog in cities — produced by Alberta's oil sands have been measured at levels up to 6,300 per cent higher than we thought. John Luggio, a research scientist with Environment and Climate Change Canada, said their cutting edge techniques in their new study picked up many pollutants industry hasn't been required to track. Mark Cameron from Pathways Alliance, the industry group representing several oil sands companies, agreed that these findings warrant further review. Megalodon was enormous — but perhaps less husky than we'd thought (9:20) The extinct shark megalodon was likely the largest predatory shark to ever swim the oceans, but a new reconstruction suggests it was not quite the behemoth we thought it was. Scientists had assumed it was beefy and thick like a modern great white shark, but a new study says the evidence suggests it was a slim, sleek killer.Philip Sternes, a PhD candidate at the University of California, Riverside in the department of evolution, ecology and organismal biology, worked with a team of 26 international scientists on the study featured in Palaeontologia Electronica. Astronomers find a planet with a massive, gassy tail (17:46) Observations of a large, Jupiter-sized exoplanet closely orbiting a nearby star have revealed that the planet has a huge, comet-like tail. The 560,000 kilometer-long tail seems to be a result of the powerful stellar wind from the star stripping the atmosphere away from the gaseous planet, and blowing it out into space. The find was made by a team at University of California Los Angeles, including astrophysicist Dakotah Tyler, and was published in The Astrophysical Journal. Put down your laptop, pick up your pen — writing stimulates brain connectivity (26:22) A new study looking at the activation of networks in the brain associated with learning and memory suggests that writing by hand produces much more brain connectivity than typing on a keyboard. This adds to the evidence that writing by hand is an aid to memory. Audrey van der Meer, a professor of neuropsychology and director of the Developmental Neuroscience Laboratory at the Norwegian University of Science and Technology, led the work, which was published in Frontiers in Psychology. The aftermath of a record-smashing volcano: Hunga Tonga–Hunga Haʻapai two years later (34:09) The aftermath of the record-smashing Tonga volcano that'll rewrite textbooks Record-smashing Tonga volcano sheds new light on how underwater volcanoes blow In January 2022, the largest underwater volcanic eruption ever recorded devastated the seafloor of the southwestern Pacific. A tsunami washed ashore in nearby Tonga — causing significant property damage, but thankfully taking few lives. Kevin Mackay, a marine geologist from the National Institute of Water and Atmospheric Research in New Zealand, said this blast broke many records, including the loudest sound, highest eruption and fastest underwater avalanches ever recorded. And we're still feeling the heating effects from it today from the water vapour it shot into the stratosphere.
Comenzamos el programa de hoy con una noticia publicada en la revista Nature cuyo contenido se resume en una pregunta: ¿Cómo cambiarían la ciencia los superconductores a temperatura ambiente? A continuación hablamos de un estudio de la universidad Juntendo, de Tokio, que propone la elaboración de un señuelo molecular para engañar al virus SARS-CoV-2 que puede ser usado como tratamiento para la COVID-19. La tercera noticia nos acerca a una de las erupciones más explosivas en más de un siglo que tuvo lugar en el reino de Tonga provocada por el volcán parcialmente sumergido Hunga Tonga-Hunga Ha’apai. La erupción provocó un flujo de escombros submarinos que avanzó a velocidades de hasta 122 km/h por el forndo marino, alterando radicalmente el paisaje oceánico y dañando los cables submarinos que había en la zona. Por último, hablamos de un estudio del Centro Nacional de Investigaciones Cardiovasculares (CNIC) en Madrid que relaciona los factores de riesgo cardiovascular con el riesgo de sufrir enfermedades neurodegenerativas.

In this episode of Earth SciShow, we explore the extraordinary eruption of the Hunga Tonga–Hunga Haʻapai volcano in January 2022, which created the tallest volcanic plume ever recorded. We talk to Dr Simon Proud, a senior scientist at Oxford University and one of the authors of a new study that used satellite images and a technique called 'the parallax effect' to measure the height of the plume. We also discuss the implications of this eruption for the global stratospheric composition and climate.
Many of the biggest threats that live in the ocean can't be seen from the surface. Dr Izzy Yeo joins the podcast and covers some of the biggest marine geohazards, including underwater volcanoes. She also covers the devastating local and global impacts of the Hunga Tonga–Hunga Haʻapai volcanic eruption, which was the most explosive volcanic eruption of the 21st century.

Almost a year on from Tonga's devastating undersea volcanic eruption, volcanologist Shane Cronin asseses the impact and implications for monitoring other Pacific fault lines. The Hunga Tonga-Hunga Ha apai eruption in January generated a huge tsunami that reached the coasts of Japan and the Americas, claiming six lives, injuring 20 people and causing damage in excess of 100 million dollars. The submarine volcano lies around 65 kilometres north of the Kingdom's main island, Tongatapu, and it was biggest atmospheric explosion recorded on Earth in more than 100 years. It is part of the active Kermadec-Tonga subduction zone and the volcanic arc associated with it extends from New Zealand to Samoa. Since the eruption University of Auckland vulcanologist Shane Cronin has been back to Tonga, leading the local science response and identifying ongoing hazards.

Fred Pollitz, USGS ESC Moffett Field The 15 January, 2022 eruption of Hunga Tonga Hunga Ha’apia is the largest since the 1991 Mount Pinatubo eruption. It produced a local tsunami with up to 15 m height and inundation of 500m; a plume that eventually reached 58 km height; globally recorded infrasound waves through Earth’s atmosphere; acoustic-gravity standing waves at two dominant resonant frequencies; worldwide sea waves driven in part by the atmospheric Lamb pulse. It produced globally observed seismic signals from coupling of the different atmospheric waves with the solid earth, as well as direct signals from the volcano due to the reaction force. We explore different seismological approaches to deriving the source time function of the reaction force, which is well characterized as a sequence of Impulsive vertical forcing that produced seismic wave energy in multiple packets for 5000 s after the initial Surtseyan eruption, with a late burst around 15000 s. The seismological results are consistent with the generation of the eruptive plume that expanded rapidly for the first 90 minutes, implying average forces of 10^12 N over this time but reaching magnitudes as high as 2x10^13 during the eruption subevents.

Reconstruction and recovery efforts continue in Tonga with millions of dollars still pouring into the kingdom following January’s violent underwater eruption of the Hunga Tonga-Hunga Haʻapai volcano. For scientists, trying to understand what caused that massive blast and what it may mean in terms of future risk, could take years of research. Leading the charge is Auckland University Volcanologist Shane Cronin, the first expert who’s been able to see first-hand the effects of the eruption. Joining Tova on Tuesday morning, Cronin explained what his mission in Tonga currently is.See omnystudio.com/listener for privacy information.
Just over two months ago, the undersea volcano of Hunga Tonga erupted catastrophically, generating huge tsunamis and covering the islands of Tonga in ash. University of Auckland geologist Shane Cronin is now in Tonga, trying to piece together the sequence of violent events. Edinburgh University palaeontologist Ornella Bertrand tells us about her studies of the ancient mammals that inherited the Earth after the dinosaurs were wiped out. To her surprise, in the first 10 million years after the giant meteorite struck, natural selection favoured larger-bodied mammals, not smarter ones. At the University of Bristol, a team of engineers is developing skin for robots, designed to give future bots a fine sense of touch. Roland shakes hands with a prototype. A global satellite survey of the world's largest coastal cities finds that most of them contain areas that are subsiding faster than the rate that the sea level is rising. Some cities are sinking more than ten times faster, putting many millions of people at an ever-increasing risk of flooding. Oceanographer Steven D'Hondt at the University of Rhode Island explains why this is happening. The odds of becoming a fossil are vanishingly small. And yet there seem to be an awful lot of them out there. In some parts of the world you can barely look at a rock without finding a fossil, and museum archives worldwide are stuffed with everything from ammonites to Archaeopteryx. But how many does that leave to be discovered by future fossil hunters? What's the total number of fossils left to find? That's what listener Anders Hegvik from Norway wants to know and what CrowdScience is off to investigate. Despite not having the technology or time to scan the entire planet, presenter Marnie Chesterton prepares to find a decent answer. During her quest, she meets the scientists who dig up fossils all over the world; does some very large sums; and asks whether we'll ever run out of the very best and most exciting fossil finds.

The Kingdom of Tonga in the southwestern Pacific Ocean, east of Australia and Fiji, is made up of around 170 islands. On January 15, 2022, several islands were impacted by the massive eruption of an undersea volcano. The effects this volcano had on the islands as well as on the people of Tonga are Worth Noting.Links:“Tonga undersea volcano eruption released up to 18 megatons of energy” (Space.com, Jan. 26, 2022)“Tonga Needs Rain and More Brooms After Volcano Eruption Spewed Ash” (The Wall Street Journal, Jan. 26, 2022)Sources consulted:“Dramatic Changes at Hunga Tonga-Hunga Ha‘apai“ (Earth Observatory, Apr. 10, 2022)“NASA researchers have an estimate of the power of a massive volcanic eruption that took place on Saturday near the island nation of Tonga.” (@NPR, Instagram, Jan. 19, 2022) “Tonga” (Britannica, accessed Jan. 21, 2022)“Before & after images reveal impact of undersea volcano eruption and tsunami in Tonga” (USA Today, Jan. 22, 2022)“NASA Says Tonga Eruption Was More Powerful Than an Atomic Bomb” (Smithsonian Magazine, Jan. 25, 2022)“Satellite images show the aftermath of Tonga volcano's eruption” (NPR, Jan. 26, 2022)

Join us as we interrupt our water series re-release to talk about a major current event - the eruption of Hunga Tonga-Hunga Ha'apai volcano in Tonga.It was a huge eruption in the South Pacific from a very active volcano. Its had some smaller eruptions in the last few months, but Saturday morning took the lid off.In fact, some instrumented Cascade volcanoes - Mt Hood, Mt Saint Helens, and Mt Ranier, detected infrasound records (essentially specialized microphones). The second longer but lower-magnitude signal that shows up later in the plot - is the airwave passing by the station again -- having come from the other direction! That's right, the airwave has wrapped around the planet! The first wave traveled a distance of ~8500 km (~5300 miles). The second traveled ~32,500 km (20,200 miles)! In fact, barometers at O'hare airport in Chicago picked up the compression sound waves.You may be wondering: why was there a volcano here in the first place? The answer is: plate tectonics! Tonga is one of the volcanic islands located on top of the Tonga Kermadec subduction zone! This is the convergent plate boundary where the Pacific Plate sinks below the Australian Plate. The Pacific Plate is made of old, cold, and dense rock material that sinks beneath the Australian Plate, where the subducted rocks heat up and melt as crust is recycled. The water and other volatiles rise up as the rocks are melting -- contributing to the "Big Boom" of the eruption.Why are the eruptions so violent? Potentially? It's not always violent, but about every thousand years, it let's loose with huge eruptions. Why doesn't the cool ocean water cool the magma? If magma rises slowly, there will be a thin layer of steam between the water and the magma. This will allow the outer edge of the magma to cool. If the magma rises fast, the magma is in direct contact with the water. The result is much like a weapons grade chemical explosion that starts a chain reaction where fresh magma is exposed to new water. So this is a combination of magma/water interaction as well as gas charged sticky magma that has been building for the last 1000 yrs. By studying deposits from past eruptions, we know that we might be in for several weeks (or years) of intense volcanic activity. The violence of the blast triggered tsunamis. About 1.2 meters (4 feet) on the country of Tonga. Hard to get a clear picture of devastation yet because of ongoing eruptions. I don't think this story is done yet.Ash reached 20km into the sky and it produced a ton of lightning ~ 100 bolts/sec!——————————————————Instagram: @planetgeocastTwitter: @planetgeocastFacebook: @planetgeocastEmail: planetgeocast@gmail.comWebsite: https://planetgeocast.buzzsprout.com/
19 de enero | Nueva YorkHola, maricoper. Me han invitado a participar en una versión de El juego del calamar en Minecraft en la que participarán mogollón de streamers como Ibai, Rubius y Auronplay. No sé si seré el único atontao que no ha jugado al Minecraft en su vida, pero la cosa promete teniendo en cuenta que probablemente no dure más de dos segundos vivo.* Os espero en mi Twitch para animarme a eso de las 18:30 hora peninsular española.Bienvenido a La Wikly diaria, una columna de actualidad y dos titulares rápidos para pasar el resto del día bien informado.

15 stycznia na Oceanie Spokojnym wybuchł wulkan Hunga Tonga–Hunga Haʻapai, na północ od Nowej Zelandii i Północny Wschód od Australii, w pobliżu państwa Tonga, obejmującego archipelag Tonga. Jakie były okoliczności i konsekwencje tej erupcji? O zdarzeniu rozmawiam z Bartkiem Krawczykiem z „Wulkanów Świata”.
After a month's break, here we are! We're back for a new season of the podcast, Season 3!!!In this episode, after a quick updates on the world's volcanic activity over the past month, Corin and Alessandro chat a bit about the recent eruption occurred at The Hunga Tonga-Hunga Ha'apai!
The pacific region is continuing to assess the impact of the Hunga Tonga-Hunga Ha apai underwater volcano eruption. The Nationall Weather Forecasting Centre in Nadi is reporting the eruption is ongoing and continues to provide updates and forecasts while communication remains down with the whole of Tonga. Steven Meke from the National Weather Forecasting Centre joins Emile to discuss what we know currently.
The eruption of a giant underwater volcano in the Pacific Ocean has triggered tsunami warnings across the region. Alerts were raised from Australia to the United States, and now to Japan where there are warnings of possible three-metre waves. Also in the programme: US Senators introduce ‘Defending Ukraine Sovereignty Act of 2022' legislation, we hear from Chairman of the Senate Foreign Relations Committee Senator Robert Menendez, and the 400th anniversary of Molière.
