  • Doomsday Volcanoes: Will Another Icelandic Volcano Erupt? | Full Documentary | Reel Truth. Science

    52:06

    April 2010 saw the eruption of Iceland's Eyjafjallajökull volcano, which caused Europe to become an ash-strewn no fly zone, causing millions of flights to be cancelled. But this seems to be just the start. The Icelandic volcano Katla has started to swell and grumble plus two more giants, Hekla and Laki could erupt without any warning. Iceland is becoming geological monster and when the volcanoes erupt the consequences could be global. In this documentary atmospheric scientists look closer into what the impact would be if there was an eruption and also how we can prepare ourselves for the aftermath that would follow.

    Subscribe to Naked Science –

    Our quest for a new home has brought us a long way, we are 365 million miles from Earth, in orbit around the planet Jupiter.

    Io is the innermost of the four Galilean moons of gas giant Jupiter and the most volcanic body in our solar system, spewing lava from its superheated interior. It is the fourth largest moon, has the highest density of all the moons, and has the least amount of water of any known astronomical object in the Solar System. It was discovered by Galileo Galilei in 1610 and named after the mythological character Io, a priestess of Hera who became one of Zeus' lovers.

  • Krakatoa Volcano - The Calm before the Cataclysm

    Subscribe to Naked Science –

    As controller for Ketimbang, one of William Bering’s responsibilities was to report large tremors to his superiors in Batavia, but having no clue where the tremor had come from, or what had caused it, he was unaware of the danger that lay only 23 miles out to sea.

    Just before midnight on 9th May 1883 intense pressure building deep beneath the earth’s crust broke through the line of weakness directly below Krakatoa. Magma moving towards the surface split the crust apart creating a large tremor. The lighthouse keeper at Forth Point Lighthouse saw the sea freeze, becoming calm and flat for an instant. What he witnessed is now recognised as the first documented warning sign of the beginning of Krakatoa’s 1883 eruption.

    To momentarily freeze the waters of the Sunda Strait required incomprehensible geological forces. After 200 years of dormancy Krakatoa was about to wake from its slumber.

  • Cosmic Journeys - Supervolcanoes

    28:05

    They are eruptions so vast, so Earth-shattering, they have changed the history of our planet. Climate collapse. Toxic turmoil. Mass extinction. Worse than a killer asteroid, or nuclear war, they are Earth's most destructive Supervolcanoes.

    North America, the time was six hundred and forty thousand years ago, long before humans arrived on the continent. Amid one of nature's great mountain building projects, the Rockies, vast columns of smoke began to rise high into the atmosphere. And soon a smokey haze wrapped the globe.

    A thick blanket of ashe spread over the western United States. Geologists have traced this event to a depression in the land known as a caldera, in the heart of Yellowstone National Park in Wyoming. Today, we venture to Yellowstone to admire its spectacles of steam and boiling mud.

    Visitors to Yellowstone may never suspect they are atop one of the world's largest active volcanoes.

    The last time it blew, it sent an estimated 1000 cubic kilometers of dirt, rocks, ashe, dust, and soot into the atmosphere. But that's small compared to Earth's largest super volcanoes. Find out what made Toba, Siberian Traps, Deccan Traps and other super eruptions so powerful.

  • Supervolcano in Utah: Massive Ancient Volcano Discovered by BYU Geologists

    4:22

    For 30 years, BYU geologists have searched for the volcano that produced thousands of cubic kilometers of pyroclastic flow on the Utah-Nevada border. Piecing together the geologic evidence from five different mountain ranges across hundreds of miles, they report in Geosphere the discovery of a massive 30-million-year-old supervolcano in Utah. The ancient caldera, which would have been several miles deep, is no longer visible as it has eroded and filled with pyroclastic flow many years ago. The original Wah Wah Springs pyroclastic deposit associated with this caldera covered an area of ~12,000 square miles and had a volume of 5,900 cubic kilometers or ~1,400 cubic miles (6,000 times the size of the Mount St. Helens eruption that emitted just one cubic kilometer of material). The researchers report that this is one of the largest documented supervolcanoes worldwide.

    SEE MORE FROM NEWS.BYU.EDU (news.byu.edu/archive13-dec-supervolcano.aspx):
    Brigham Young University geologists found evidence of some of the largest volcanic eruptions in earth's history right in their own backyard.

    These supervolcanoes aren't active today, but 30 million years ago more than 5,500 cubic kilometers of magma erupted during a one-week period near a place called Wah Wah Springs. By comparison, this eruption was about 5,000 times larger than the 1980 Mount St. Helens eruption.

    In southern Utah, deposits from this single eruption are 13,000 feet thick, said Eric Christiansen, the lead author for the BYU study. Imagine the devastation -- it would have been catastrophic to anything living within hundreds of miles.

    Dinosaurs were already extinct during this time period, but what many people don't know is that 25-30 million years ago, North America was home to rhinos, camels, tortoises and even palm trees. Evidence of the ancient flora and fauna was preserved by volcanic deposits.

    The research group, headed by Christiansen and professor emeritus Myron Best, measured the thickness of the pyroclastic flow deposits. They used radiometric dating, X-ray fluorescence spectrometry, and chemical analysis of the minerals to verify that the volcanic ash was all from the same ancient super-eruption.

    They found that the Wah Wah Springs eruption buried a vast region extending from central Utah to central Nevada and from Fillmore on the north to Cedar City on the south. They even found traces of ash as far away as Nebraska.

    But this wasn't an isolated event; the BYU geologists found evidence of fifteen super-eruptions and twenty large calderas. The scientific journal Geosphere recently published two of their papers detailing the discoveries.

    Despite their enormous size, the supervolcanoes have been hidden in plain sight for millions of years.

    The ravages of erosion and later deformation have largely erased them from the landscape, but our careful work has revealed their details, said Christiansen. The sheer magnitude of this required years of work and involvement of dozens of students in putting this story together.

    Supervolcanoes are different from the more familiar stratovolcanoes -- like Mount St. Helens -- because they aren't as obvious to the naked eye and they affect enormous areas.

    Supervolcanoes as we've seen are some of earth's largest volcanic edifices, and yet they don't stand as high cones, said Christiansen. At the heart of a supervolcano instead, is a large collapse.

    Those collapses in supervolcanoes occur with the eruption and form enormous holes in the ground in plateaus, known as calderas.

    Not many people know that there are still active supervolcanoes today. Yellowstone National Park in Wyoming is home to one roughly the same size as the Wah Wah Springs caldera, which was about 25 miles across and 3 miles deep when it first formed.

    More than a dozen undergraduate and graduate students made significant contributions to Best and Christiansen's papers. Hundreds of other students were involved with the geologic mapping of the volcanic areas.

  • These Mega-Colossal Eruptions Dwarf The Yellowstone Supervolcano

    10:02

    The Yellowstone Supervolcano erupted 3 times in the past 2.1 million years.
    But even the last full scale eruption of the yellowstone supervolcano, the lava creek eruption about 640,000 years ago, is dwarfed in comparison to the top mega-colossal eruptions of supervolcanoes throughout our planet's history.

    The yellowstone supervolcano ejected a magma volume of about 1,000 cubic kilometers.

    But The toba eruption which is also known as the Toba event, about 74,000 years ago, ejected at least 2,800 cubic kilometers of magma. There are even larger Supervolcanoes than Toba.

    La garita Caldera is one of them with about 5,000 cubic kilometers of ejected volcanic material.

    And perhaps the biggest and most powerful super-eruption as a single volcano in Earth's history, is the Wah Wah Springs eruption with about 5,900 cubic kilometers of ejected magma.

    Somewhere in our galaxy, at some time in the future, a spacecraft from Earth will encounter the most dangerous object in the Universe. A stunning visual journey into black holes, their structure and their creation.

    A black hole is a geometrically defined region of spacetime exhibiting such strong gravitational effects that nothing, including particles and electromagnetic radiation such as light, can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

  • Lake Toba Supervolcano: The Mega Eruption 77,000 Years Ago

    #laketobasupervolcano #tobasupervolcano #laketobasupervolcanoeruption #tobasupervolcanoeruption
    This Supervolcano, located at Lake Toba in Indonesia, is still very much alive today. 77,000 years ago the Lake Toba Supervolcano erupted with a force that was unlike any in modern history, dwarfing both yellowstone and campi flegrei in size. Being the second largest Supervolcano eruption the Earth has ever witnessed & the Lake Toba Supervolcano is the Largest Mega Eruption & Supervolcano that humans have survived through. Its Mega eruption caused Earth shattering consequences. In this video we will document the processes necessary for supervolcanoes to awaken and cause mega eruptions, and what it takes for them to decide the moment is right to surface. Alongside this we will document exactly what happens when these slumbering beasts awaken to cause chaos upon the Earth.
    The Lake Toba Supervolcano is very interesting, aside from being one of the many volcanoes of South East Asia like Krakatoa that caused it's own massive eruption, the Lake Toba Supervolcano is in a category of its own. It was so large that it's fallout spread to every corner of the Earth.

    Subscribe to Naked Science -

    Every other Wednesday we present a new video, so join us to see the truth laid bare...

    This spectacular five-part documentary series, presented by Tony Robinson, investigates the history of natural disasters, from the planet's beginnings to the present, putting a new perspective on our existence and suggesting that we are the product of catastrophe.

    99% of all the creatures that have ever lived, no longer exist. They were wiped-out in a series of global catastrophes. Each disaster changed the course of evolution on earth. Without them mankind, nor any of the life we see around us, would be here today. For out of catastrophe comes rebirth. Evolution is a savage, imperfect and violent process. It's survive or perish. The earth's history of catastrophes has both moulded the planet and determined evolution. For each disaster led to another leap forward on the evolutionary trail form single celled bacteria to humankind itself.

    Episode 2 - Snowball Earth

    This programme delves into a world lying beneath a frozen surface. It is the greatest climate disaster ever to have hit Earth. 650 million years ago, a cataclysmic ice age sealed the entire planet beneath ice and snow, almost destroying life and turning the world into one huge snowball.

    Snowball Earth uncovers the story behind one of the most controversial theories in science today. To investigate, the programme travels the world to follow scientists scouring southern Australia, Nevada's Death Valley and Alaskan glaciers for tantalising clues as to how our planet ran away into this doomsday scenario. The results could improve understanding of evolution and survival of life.

  • 88,000 tons of radioactive waste – and nowhere to put it

    7:39

    The United States produces 2,200 tons of nuclear waste each year…and no one knows what to do with it. The federal government has long promised, but never delivered, a safe place for nuclear power plants to store their spent fuel. This means that radioactive waste is piling up all over the country. We visited one of the worst places where the waste is stuck: a beachside power plant uncomfortably close to both San Diego and Los Angeles. And we asked the people in charge of the waste there: what happens now?

  • What’s happening at Kīlauea Volcano’s summit?

    49:28

    Kīlauea Volcano's summit has been in an eruptive pause since the 2018 events ended over a year ago. Nevertheless, it remains a dynamic place. Ongoing inflation and seismicity indicate that the summit magma chamber is gradually recharging. A water lake, unprecedented in the written historical record, appeared at the bottom of Halema‘uma‘u in late July 2019 and has steadily risen. What are the potential hazards at Kīlauea’s summit? Could explosive activity return? What is known about the water lake? How is it monitored? USGS Hawaiian Volcano Observatory geologists Matt Patrick and Tricia Nadeau answer these questions and more in this Volcano Awareness Month talk presented on January 14, 2020. Volcano Awareness Month is spearheaded by the USGS–Hawaiian Volcano Observatory, in cooperation with Hawai‘i Volcanoes National Park, and provides informative and engaging public programs about the science and hazards of Hawaiian volcanoes.

  • The Secrets Of The Lost Persian Empire | Lost Worlds | Timeline

    49:24

    Lost Worlds investigates the very latest archaeological finds at three remote and hugely significant sites - Angkor Wat, Troy and Persepolis. Lost Worlds travels to each site and through high-end computer graphics, lavish re-enactment and the latest archaeological evidence brings them to stunning televisual life. From the 900-year-old remains of Angkor Wat in the Cambodian jungle the staggering City of the God Kings is recreated. From Project Troia, in North West Turkey, the location of the biggest archaeological expedition ever mounted the lost city is stunningly visualised and finally from Persepolis the city and the great Persian Empire are brought to life.

    I learned a lot in making this video and the one on my second channel with Prof. Jon Arnou. I changed a lot of my preconceptions, specifically I thought:

    1. That the Earth's magnetic field was a passive thing - it shouldn't need a continuous input of energy to maintain itself (that seemed reasonable to me because the magnetic field has been around for a long time and it seems mostly stable). But as it turns out, the Earth is a giant electromagnet, and so of course those currents dissipate their energy as they encounter resistance in the liquid metal through which they flow. So the energy to continuously create these currents comes from the kinetic energy of the liquid metal flows in the Earth's outer core.

    2. If it's convection, I'm thinking hot things rising, cooler things falling. But apparently the main effect driving convection is the compositional differences at the boundary with the Earth's inner core. This is because of the differential freezing at the boundary. Things like iron freeze into the inner core, while elements like sulfur do not. Hence the pockets of lighter material which then rise outwards.

    3. I didn't get why the fluid motion was necessary for the generation of the magnetic field. I mean if it's a conducting liquid, it can conduct currents whether it moves or not. But the key is that the liquid metal can 'trap' magnetic fields. I imagine this like how iron channels magnetic fields. Then once these fields are channeled, they can be pulled and stretched, making more magnetic field.

    4. Fluids operate very differently in rotating frames of reference. This is something I didn't intuitively grasp. But, as fluids move from the inner core outwards, those particles are moving much more slowly in the direction of rotation than the matter that has been there for a long time, which means the convection currents get deflected and form helices.

  • Whats 4,000 Times More Destructive Than The Yellowstone Supervolcano?

    3:42

    The Yellowstone Supervolcano's last eruption about 640,000 years ago ejected more than a 1,000 cubic kilometers of volcanic ash into the sky. But even that is next to nothing compared to the destructive power of a Flood Basalt Which are a series of volcanic eruptions lasting for thousands up to millions of years. The volcanic eruptions that formed the Siberian Traps are an example of a flood basalt, and they filled today's Sibera of the super continent Pangea with basaltic lava more than the surface area of the E.U. The flood basalt which created the Siberan Traps ejected about 4,000 times more volcanic material than the lava creek eruption of the yellowstone supervolcano. It is thought this basalt event caused the Permian extinction. Watch the video to learn more about Flood Basalts and how they compare with the yellowstone supervolcano.

    11:11

    Scientists have said this happened to the Yellowstone Supervolcano in 2019. Today, we take a look at what happened to Yellowstone National Park in 2019.

    2019 has been a busy year at the Yellowstone National Park. For the past 10 months scientists and researchers based at the National Park have been giving us an insight into whats been going on. For some Yellowstone is one of the most picturesque places you can visit.

    It covers over 3,400 square miles and research has shown that interest in the park is on the increase. In fact over 3.8 million people have visited the park this year, this has been the most amount of people since 2010.

    Music by Epidemic Sound:

    NOTES
    Melatonin is a hormone that is produced by the pineal gland in your brain. While melatonin isn’t very effective for treating general insomnia, it IS good for jet lag. Melatonin was found to be effective for jet lag (in people traveling across five or more time zones) by several placebo-controlled trials:
    More information on melatonin:

    In general, you should avoid alcohol while you’re trying to adjust to a new time zone. While alcohol can help you fall asleep, it interferes with staying asleep and decreases sleep quality. And not getting restful sleep is only going to make jet lag worse.

    Caffeine isn’t necessarily bad, as long as you aren’t drinking it within 4-6 hours of bedtime. It might even help you adjust to a new time zone, but only if you’re travelling east – although this isn’t conclusively proven yet.

    REFERENCES ????
    It’s generally easier to travel west than east
