Officials Panic After the California Supervolcano is on the BRINK of Eruption!

it's been 760,000 years since the last eruption and the world is holding its breath as they await what could be a seismic event that has never been seen before unlike your everyday volcano this super volcano isn't just a mountain with a temper imagine Mount Everest but with a hidden reservoir of molten rock so immense it could fill the Grand Canyon several times over California super volcano nestled within the Eastern Sierra Nevada mountain range is also known as Long Valley Caldera it spans approximately 20 m in width and 11 m in length formed by extremely large chamber volcanic eruptions the Caldera has witnessed several major events with the most recent occurring around 760,000 years ago 760,000 years that is a whole lot even in geological time what is a Caldera it is a large basin shaped volcanic depression in the earth's surface that forms after a volcanic eruption it's much bigger and deeper than the original volcanic crater picture this when a volcano erupts violently it can empty out the magma chamber beneath it with no support from the magma the volcano collapses inward creating a large bowl-shaped depression called a Caldera this type of volcano contrasts with shield volcanoes which have broad gentle slopes formed by the accumulation of fluid lava flow or Strat volcanoes which are characterized by steep slopes and periodic explosive eruptions due to their sticky magma composition history of Caldera around the world Yellowstone Caldera located in Yellowstone National Park Wyoming USA is one of the largest calderas on Earth measuring about 34x 45 Mi it is a hotspot volcano characterized by frequent hydrothermal and seismic activity santor Caldera sit situated in the aian sea as parts of the Cycles islands in Greece became popular for its dramatic eruption around 1600 BCE during the late Bronze Age the eruption was so powerful that it led to the collapse of the central part of the island this event is often associated with the decline of the Manan civilization on the nearby Islands tupo Caldera found on New Zealand's North Island was formed through several major eruptions the most recent of which occurred approximately 26,500 years ago Lake Tao now fills part of the Caldera and serves as a popular tourist destination Larita Caldera located in Colorado's San Juan mountains USA formed around 27 million years ago in one of the largest known Caldera eruptions covering an area of about 1,500 mil 3,900 Square km unique features of the California super volcano apart from being one of of the largest volcanoes in North America The Long Valley Volcano e also has some very unique features one of them is its formation of a resurgent dome unlike many other volcanoes The Long Valley volcano has a prominent resurgent Dome at its Center resurgent domes are unique geological features showing that the volcano's magma chamber is still active and capable of future eruptions another unique feature is the presence of pyroclastic flows pyroclastic flows are fast moving currents of hot gas and Volcanic matter that Rush down the slopes of a volcano during an eruption they can reach speeds of hundreds of kilomet per hour and are extremely dangerous due to their high temperature up to 1,000° C or 1,832 de F and density within the Caldera there are numerous obsidian domes rounded Mounds formed by the rapid cooling of lava flows rich in silica extensive hydrothermal alteration zones are present within the Caldera where hot water has chemically altered the surrounding rocks the Caldera hosts a significant geothermal system with hot springs gazers and ferales Scattered throughout the area The Long Valley Caldera is mostly associated with rolic volcanisms the eruption of viscous silica Rich magma this is one of the reasons why caldera's eruptions are very very explosive but what makes the Long Valley volcano really scary is its potential for a super volcanic eruption what are super volcano eruptions super volcanoes are identified by their massive eruptions that eject hundreds to thousands of cubic kilm of volcanic material making typical volcanic events look little when super volcanoes explode there is a devastating after effect with Ash Fall covering the ground and clouds of Ash that can be hundreds of meters thick what happens if the volcano eventually erupts The Long Valley volcano is one of the world's 20 known super volcanos earning a VII 8 classification on the eruption scale the sheer magnitude of this volcano has led volcanologist to believe that crisis management would be virtually impossible should it erupt in fact an eruption of more than 240 cubic M of material would be enough to cover California's 163 , 696 miles what then is the government saying about this California volcano Observatory calvo a branch of the US Geological Survey has voiced out about a major problem they face when dealing with super volcanoes their mission is to Monitor and study volcanic hazards in California according to them a major problem they face is the Rarity of super volcanoes if you're liking this video so far don't forget to like And subscribe to the Channel super volcano eruptions are considered extremely rare occurring once every 100,000 years to combat this the researchers have resolved to using machine learning algorithms which can help interpret signals of stored magma and its movement in the hours and days prior to eruption other tools that they have employed in studying the volcano are size MERS are strategically placed to detect ground vibrations caused by volcanic earthquakes these instruments help scientists track the movement of magma beneath the surface and identify patterns of seismic activity that may indicate volcanic unrest global positioning system GPS stations and satellite-based radar insar are used to measure ground deformation these Technologies detect subtle changes in the Earth's surface such as uplift or subsidence which can signal magma movement and potential volcanic activity gas sensors measure the composition and concentration of volcanic gases emitted from vents and ferals changes in gas emissions such as increases in sulfur dioxide SO2 or to carbon dioxide CO2 can indicate Rising magma and Volcanic unrest thermal cameras and satellite imagery are employed to monitor changes in temperature and thermal activity at volcanic vents this data helps scientists assess the intensity of volcanic activity and identify areas of heat buildup associated with magnet movement groundbased surveys including electromagnetic em surveys and gravity measurements provide insights into the subsurface structure and potential Pathways for magma Ascent within volcanic systems solutions profer for other super volcanoes in the past NASA proposes drilling up to 6 miles into the Super Volcano beneath Yellowstone National Park to inject water under high pressure aiming to cool it down the downside of the project is that it would cost a in sum of $ 3.46 billion however even with the economic benefits this method still carries large risks it could potentially trigger the very super volcanic eruption NASA hopes to prevent in the campy fle gr Caldera near Naples Italy engineering Solutions such as drilling into the Caldera to release pressure or redirect magma flows have been considered in Indonesia's Toba Caldera one of the largest super volcanoes known scientists have proposed drilling into the Caldera to release pressure gradually in Japan's era Caldera scientists have explored methods to cool the magma chamber by injecting water or other coolants this approach aims to lower the temperature and reduce the risk of volcanic activity that could threaten nearby urban areas with these techniques suggested by scientists all over the world do you think the government would be able to contain the effect of the line Valley volcano when it threatens to erupt let us know your
