You can guess depressed. The super volcanoes around the world. Often of the four is the cause of major fear. This is mostly due to the damage and destruction theyve caused to the earth. Over and over again, these volcanoes have been found to destroy countries, continents playing with the ecosystems of the world leading to mass extinction. Theres plenty of evidence just look back 74, 000 years ago, when mount toba threw a deadly tantrum, nearly wiping humankind off this planet. To strengthen this just look back 66 million years ago, new research suggests that the volcanic fields of the deacon flats suggest that not only an asteroid hit the earth, but at the same time, large volcanic eruption creating the decrement fields also occurred. So, regardless, if or when a super eruption may occur, if it did, it would completely change the world to what it is today. We must give credit to volcanologists who are working hard studying these giants, so you know we can really truly understand the way volcanoes mature and develop to an imminent eruption. However, on the other hand, the only true understanding would be to experience a super volcanic eruption, so the question still stands. Do we really know enough about these volcanic giants of the world to really reassure that they will not erupt for thousands of years and, secondly, what precautions have worldwide governments got in place to assure worldwide survival for the many before we dive deeper lets. Take a look into the potential candidates and what destruction they might cause for me, i believe out of the super volcanoes today there are only two potential candidates, these being the well known calderas at yellowstone.
There were three calderas at yellowstone, but for this, video well just be focusing on the hockley ridge cloud era, which last erupted 2.1 million years ago. My ad, though there are some fairies that, if the caldera were to it may lead to the eruption of the neighboring calderas, three super volcanic explosions at once would ultimately devastate this world and everyone on it. I dont think anyone would stand a chance and the second candidate is the caldera situated in indonesia, late toba, which last erupted just only 74 000 years ago. Now the reason why ive chosen these two cowdeers is purely down to the size of the magma chambers. Although scientists mentioned that these wont go super for many of thousands of years, if they did, they would shock the world leading the human race and much of the bio life to near or complete extinction, as previously shown 74 000 years ago with toba. So now we know the potential threats. What would happen if one of these eruptions decided to wreak mayhem on the planet? Well, the closest live scenarios we have is the record reports of two strata volcano eruptions, these being mount vesuvius, wreaking hazard on pompeian ad79 and the more recent explosion of krakatoa. Both reports explained increased volcanic activity leading to blackened skies, filled full of ash, leading on from this, the krakatoa eruption released its fury produced a loud bang, rupturing eardrums of sailors found to be 40 miles away.
This then led to reports of skies all around the world. Being a sunset red due to the spread of the ash, krakatoa in 1883, claimed over 36 000 limes and is still today the loudest noise ever to be reported on earth. Since records began, krakatoa was thought to be a vei6 now. This is very strong for a volcanic eruption and found to be quite rare but very dangerous, but when compared to the eruption of october and yellowstone, which is fought to be veia, this means the explosion would be thousands of times more powerful scientists exclaimed that if an Eruption was imminent, then we would have years of warning ahead of time. However, new research suggests otherwise, maybe the volcanic activity would be much quicker than we think so now the big question: what would happen if earth were to experience a super rush room measuring the same? A veia again would humans be able to survive and adapt, or just have we become so distant from our ancestors and our forgotten relationship with nature and how to survive. If an eruption were to occur lets say at yellowstone national park, the first effects would be to the regional areas, such as the states of montana, idaho and wyoming. As shown, these areas would be completely blanketed in ash experience very little sunlight upon the eruption. These areas would experience a fury of pyroclastic flows, reaching speeds in excess of 40 miles per hour very difficult to escape from, but the temperature of the pyroclastic flow would be excruciating.
Anyone in the area would be hit by wind, full of ash and debris traveling around 40 miles per hour, with temperatures of around 1 000 degrees celsius. I mean you only have to look at the remains of pompeii to have a great understanding of what would be the imminent effects of anyone within the radius of these states. However, in the case of an eruption at yellowstone, the damage would be much more widespread. The immediate effects of the explosion would be strong enough to knock down buildings. Push people to the ground turn any warsaws into a mini tidal wave. However, still to come from what weve learned from pompeii and seen in the eruption of other volcanoes, hot volcanic rock projectiles were just rained down destroying everything they hit. These rocks would literally be like mini asteroids smashing cars hitting people. In fact, the last big eruption at lava creek was estimated to have ejected approximately 240 cubic miles of rock dust and ash, but lets go back remember at the start, when we mentioned a significant memory of the krakatoa explosion, the fact that it produced the loudest sound Ever recorded by humans, well, the same would be in this case, but the noise of the explosion would be much more intensified. People in the radius of around 100 miles would easily have the eardrums burst. You would literally be deaf and thats if youre not already being hit by a rock some scientists even believe the noisy explosion would be heard worldwide, okay, its safe to say the closer.
You are to the eruption, the smaller your chances of survival. Now, at this point, if you are on the other side of the world, what is the problem so what you might hear a loud bang in a distance and thats about it? I suppose. Well done you survived a yellowstone eruption. If this is the case, then why? The worldwide panic well lets take our attention back 74, 000 years ago to the massive cataclysm eruption october. When toby erupted. It was one of the largest eruptions had a vei 8 in earths history, although yellowstone was a via the magma chamber of october, is much larger. So whats significant about toga, well, the fact that it was close to driving humans to extinction and may have also been the plain factor in the disappearance of the neanderthals. Okay, some say this wasnt the case. However, there is a lot of evidence that does support this theory. In any case, others believe homo sapiens struggled to survive, because the human population was low anyway. Lets look at this in a different way, though. Maybe humans did survive this apocalyptic event due to their relationship with the land and their ability to adapt and survive. Okay, let us take a step back again and understand why our ancestors may have struggled to survive. The mega ban caused a prolonged worldwide nuclear winter and released ash in a high plume that spread to the north west and covered india, pakistan and the gulf region in a blanket of one to five meters, thats three to fifteen feet.
Deep tobers ash is also found in greenland ice record and submarine cores in the indian ocean. Allow a precise date marker in our story. The toba eruption is the most accurately dated dramatic and unambiguous event before the last ice age. Tobit is also regarded by summers. Having caused worldwide population extinction as a result of the nuclear winter that followed that it sent the planet into a severe ice age that nearly caused the extinction of modern humans ice core evidence suggests that average air temperatures worldwide plunge by three to five degrees celsius. For years after the eruption, some model simulations estimate that the temperature decline may have been much lower. It may have been as much as 10 degrees in the north hemisphere in the first year of the event. A study of the remains of human settlement located in southern africa and dated to the time of the eruption suggests that some areas of earth for plentiful food supply may have served as refugees for humans beings in years following the eruption. I think this would be the case today if yellowstone october were so rude. However, the world population is much more larger and many people have lost their natural sense to the land. Would there be enough habitable landmass to farm and feed the many and even more worrying? Would these least unaffected countries that are only just feeding themselves allow others into their countries? I guess the world would have to unite for at least a minimum of 10 years.
However, maybe the best option would be to go alone. As we know, there are people who today live off the land in northern territories and survive just fine joining tribes or groups like these, who know the landscape and can survive through tough times ahead. Scientists say the probability of yellowstone and toba eruption is very low and probably wont erupt for thousands of years to come. But still do we truly understand everything about these volcanoes. Even a small probability is worth preparing, for i mean in my eyes kind of like the escape plan full of people below mount vesuvius.
