15 LARGE Waves and Swells

Natural disasters can strike at any time and can be so powerful that there is very little people in their path can do. Tsunamis in particular can be devastating, causing destruction and loss of life over vast areas. In this video we are taking a look. in the 15

large

st tsunamis number 15 the vajant dam the vajant dam is located in northern italy and at 860 feet high it is one of the highest dams in the world. It was built 62 miles north of Venice between 1957 and 1960 to provide electricity to the surrounding area. area but when you see pictures of the structure you will notice that something is missing from the reservoir behind it, that is because it is no longer in use as a result of a tragedy that took place in October 1963, while the dam was being filled a landslide that caused a mega tsunami in the lake the wave that formed was 820 feet high well above the top of the dam and cascaded down the other side even though the dam itself remained structurally intact The water destroyed several villages further down the valley and killed approximately 1900.

Before the tragedy people had been warned that something like this could happen but the authorities were not willing to listen because resolving the dangers would have cost huge sums of money in the end. Due to their inaction, one of the

large

st tsunamis in recent times occurred. created and the destruction it caused meant they had no choice but to permanently close the dam so there was no risk of it happening again number 14 Japan 2011. The Great Sendai Earthquake took place in March 2011 and struck the northern coast of Japan . main island of Honshu, the magnitude 9 earthquake caused an enormous amount of damage, but it was the series of tsunamis that formed in its wake that will always be remembered.

It occurred as a result of movement in the subduction zone in the Japan Trench, where a section about 190 miles long and 95 miles wide suddenly shook 164 feet to the east and 33 feet up, this drove a powerful pulse through the ocean and created a tsunami wave that was 33 feet high above the water surface, hit the coast and overwhelmed the city of Sendai and, according to some reports, managed to continue flowing six miles inland, more

waves

continued to hit along along the coast and, although they caused severe destruction to all coastal communities, the most devastating consequence took place when it hit the city of Fukushima and, more specifically, the nuclear power plant there officially ten.

Thousands of people died from the

waves

, but many more may live with the aftermath once the resulting nuclear meltdown is taken into account. It became one of the largest nuclear events in history and one that is still being clarified to this day number 13. Greenland 2017 The icy regions around the Earth often see major changes to the landscape when chunks of ice break apart. They collapse into the ocean and these can sometimes be so large and weigh so much that they trigger large waves that have the potential to be incredibly destructive in June In 2017 a landslide occurred in the Kharat Fjord and on the west coast of Greenland and this is believed to have created one of the biggest waves in recent times.

It is a normally serene and impressive place, but that day things took a very different turn, such large amounts of material fell. It is estimated that the water that created a mega tsunami was up to 330 feet high and crossed the bay. The residents of Nugatsiak, a fishing village on an island about 12 miles away, did not know that the wave was heading towards them and when they realized it was too late, eleven houses were swept away without a trace and four people lost. life it is surprising that such a large wave caused so few casualties but that is simply because the region that had occurred had very few communities if it had hit a more populated area the death toll would have been much higher so In many ways the result was quite fortunate.

Researchers have since found other sites in the region where a similar landslide appears very likely, so several villages have been permanently evacuated to prevent it. any loss of life in the future number 12 indonesia 2018 on september 28, 2018, a magnitude 7.5 earthquake struck central providence sulawesi in indonesia and while the earthquake itself caused a significant amount of damage, it was not nothing compared to the force of the tsunami that also created at a height of between 20 and 30 feet above normal sea level, crashed into the coast and caused widespread destruction. The human cost was also extreme: 2,000 people are believed to have lost their lives and another 4,400 people were seriously injured.

It is estimated that some 68,000 homes were completely destroyed and the effects of the damage displaced around one and a half million people. However, this was not the only tsunami to hit the region that year, as another was formed by volcanic activity on December 22 of this year. When it hit the coast of the islands of Java and southern Sumatra, it decimated communities there with 400 fatalities, even though huge sums of money have been invested in early warning systems along the coasts of that part of the world, there are so many possible ways a tsunami could form. that very often there is simply not enough time to get the word out so people can take shelter, while the tsunamis developing near Indonesia are by no means the largest ever seen in the world;

They hit areas so densely populated that they are undoubtedly some of the deadliest number 11 Samoa 2009. On September 29, 2009, an 8.1 magnitude earthquake struck the South Pacific and was the largest earthquake measured worldwide that year. . As soon as it hit, there were concerns about the possibility of a tsunami and the Pacific Tsunami Warning Center. issued alerts after detecting a three-inch rise in sea level near the epicenter, although this may not seem like much, it means that a large amount of energy has been released into the ocean and they were right to be concerned because when the wave hit the nearby islands had become a monster american samoa samoa and tonga were the most affected countries when the tsunami reached the beaches of samoa it was 46 feet high fortunately there was time to evacuate most of the people in its path but Not everyone was so lucky.

The wave killed 189 people, most of whom were children; virtually every structure built along the coast was knocked down. Power outages were reported across the island and the cost of all damage was estimated at around $150 million. 3,000 people were left homeless and several years passed before the country could recover from the damage caused. It remains the most powerful tsunami to hit that South Pacific region in living memory and research is now underway to try to find out if anything else is likely to happen. sometime soon number 10 ask a volcano ascial volcano is in the central highlands of iceland and at 4,900 feet high it is one of the largest active volcanoes in the country next to it is lake osceovatin which was formed in a crater left by an eruption in 1875 and it was there that an almighty mega tsunami formed in July 2014.

The lake itself is the second deepest in Iceland, reaching a depth of up to 712 feet, so when the volcano released a huge rockslide there was enough water to disturb it. The surge reportedly traveled more than a mile and a half across the lake to the opposite shore, where it rose more than 260 feet into the air before crashing onto the shore. It wasn't just the size of the wave that was surprising. but also its speed, it was traveling at more than 60 miles per hour when it hit the ground and destroyed everything in its path. The lake is a popular tourist destination during the summer months, so there were hundreds of people there that same day.

It was just a matter of luck that the tsunami hit around midnight. Fortunately there was no one around, so there were no fatalities, but if it had happened a few hours earlier, things would have been very different. Number Nine: Spirit Lake Washington Spirit Lake is just to the north. of Mount Saint Helens in Washington state and before the volcano's eruption in 1980, it was a popular resort with several luxury lodges around its shores on March 20 of that year, although the area was subjected to an earthquake that triggered the activity of the volcano. Just two months later, another triggered an eruption so violent that the entire north face of the mountain collapsed in an event that remains the largest debris avalanche ever to take place.

A large proportion fell directly into the Spirit Lake and formed a In one of the largest mega tsunamis on record, a series of waves traveled through the water and at times the waves reached a terrifying 850 feet above sea level. normal water. The surrounding environment was completely destroyed by the two events with the tree line above the reach of the tsunami. being destroyed by the pyroclastic surge of the eruption, those below the water line were swept away and swept into the lake, needless to say all structures that were in the path of the wave or eruption were completely destroyed and several lives were also lost.

The cost of rebuilding, especially with the risk of this happening again, was considered too high, so the shores of the lake have remained relatively undeveloped since then, we are constantly adding more people to the top five production team to provide them with the better content. subscribe with notifications and hit the like button number eight in Alaska, 1964. Early in the morning on March 27, 1964, what is known as the Great Alaska Earthquake occurred in south central Alaska and measured a magnitude of 9.2 and lasted four minutes and 38 seconds. At the same time 600 miles of fault opened and what remains the most powerful earthquake ever recorded in North America caused enormous amounts of damage across the state, but in many ways the worst was yet to come: the earthquake triggered a series of tsunamis one that was a direct result of tectonic activity and up to 20 or more that were formed by underwater landslides a 27 foot wave was responsible for destroying the town of chenega and killing 23 people while another that was measured at 220 feet high swept across the bay Incredibly tsunamis that formed from the earthquake were detected in at least 20 other countries and caused damage as far away as Hawaii, Japan, New Zealand and Mexico In Alaska the cities of Whittier Seward and Kodiak were severely hit by large waves and the resulting tsunamis are estimated to more than double the total cost of damage and loss of life that was caused by the first earthquake number seven unzen japan 1792 tsunamis fortunately are not that common, there has only been one A handful of those that do are classified as mega tsunamis that have occurred in recent centuries.

One of the most devastating took place in Japan in 1792 and the scars of the events of that year can still be seen. On May 21, Mount Unzen was caused by a series of earthquakes that caused it to initially erupt and then partially collapse, the debris almost completely destroying the city of Shimbara and continuing until it was deposited in the bay area. Such a large volume of material entering the water immediately triggered a massive tidal wave that at its peak reached 187 feet. high to make matters worse, after crossing the bay, it bounced off the other side and hit what was left of shimabara again.

The total death toll in the event is estimated to be fifteen thousand people, five thousand of them are believed to have died in the landslide and another five thousand died when the mega tsunami crossed the bay and another five thousand succumbed to the wave. when he returned and hit shimabara for the second time number six love on net lake norway lovet net lake is a mountain lake in vestland county in norway and is exactly the kind of stunning place you would expect from mountainous terrain. It is fed by meltwater and ice from the surrounding mountains and has historically been a popular place for visitors, but the things that make it such an idyllic and seemingly serene environment are also what make it extremely dangerous.

In fact, the lake has formed mega tsunamis on two different occasions; in January 1905, a landslide dumped 460,000 cubic yards of material into the water from a height of 1,600 feet and this triggered three tsunamis that reached up to 133 feet high. , they crossed the lake and destroyed two local villages, killing 61 people, which represented half of their population, in addition to destroying most of the houses, 261 farm animals and even launching a fishing boat almost a thousand feet inland from where it had been moored after this, there was concern about whether the community should be rebuilt, but after surveying the area, geologistsThey determined that the risk was negligible, therefore everything unfolded once again, but this would not last long in 1936 another landslide occurred which deposited 1.3 million. cubic yards of material into the water from a height of 2600 feet and this created a tsunami that was again 243 feet high, destroyed all the buildings in the area and killed 74 people and, unsurprisingly, to this day very few people have decided to make this place is home number five to disenchantment bay disenchantment bay is a 10 to 10 mile stretch of water that lies between the mouth of russell fjord and the head of yakutat bay in Alaska.

A Spanish explorer gave it its name in 1792 and entered thinking it was so. would lead to the Northwest Passage, but was disappointed when he realized that it was a dead end, it is surrounded by glaciers and large ice sheets and it is not unusual for them to break off and fall into the water, but on July 4, 1905, a unusually large A piece fell into the bay and caused an extraordinary mega tsunami. An overhanging glacier now known as the Fallen Glacier broke away from a larger sheet of ice that slid across the valley down a steep 1,000-foot slope toward the bay.

It was so large that it cleared a half mile wide swath of vegetation as it passed and generated a huge wave when it finally entered the water. There was no one there at the time but the size of the wave can be inferred by the destruction it left behind. tree branches less than half a mile away that were 110 feet above the normal water level. Vegetation three miles away was affected up to a height of 115 feet. People in nearby Russell Fjord noticed that water levels changed up to 20 feet for half an hour after the tsunami formed, all of which shows how powerful it was. number four sea of ​​mamara 1999 the sea of ​​marmara is an inland sea within turkey that connects to both the black sea and the aegean sea as a vital route that has long been important for trade throughout the region and there is a series of settlements along its However, on the coast it lies above a tectonic line called the North Anatolian Fault, which has been particularly active in recent years.

Things came to a head in 1999, when the fault caused two earthquakes, the first of which shook the city of Ismet and killed 17,000 people. A magnitude 7.6 earthquake ruptured the fault for 93 miles, part of which directly affected the Mamara Sea, causing a significant tsunami that reached up to 10 feet high above normal water level, but because the Land around the lake is very flat and the underwater topography unusual. of the place this was more than enough to cause serious damage the wave itself killed 155 people and encouraged hundreds more to move away because the risk of it happening again number three indonesia 2004. the indian ocean tsunami in 2004 was not By no means the most powerful or largest tsunami in recent times, but because it hit such a densely populated region it was by far the deadliest and most devastating in modern history.

On the morning of December 26, a massive underwater megaearthquake struck off the coast of Indonesia and measured a magnitude of 9.3. This activity triggered a series of tsunamis, one of which reportedly reached thirty meters in height and crashed into coastal communities around the ocean. Cities and towns in Indonesia, Sri Lanka, India and Thailand were particularly affected without an early warning system. The first they knew of the imminent threat was when they saw it coming, there was virtually no time to escape and this is partly what contributed to such loss of life: up to 228,000 people are believed to have lost their lives to the tsunamis and many more. were displaced Studies of the wave have found that it contained the equivalent of about 5 megatons of TNT of energy, which is more than the total use during World War II, even if you include nuclear bombs, the waves were so strong that in some places They reached more than a mile inland and traveled so far across the ocean that a five-foot surge was detected in South Africa, which is 5,000 miles away number two, the Krakatoa eruption Krakatoa is one of the most famous volcanoes on earth thanks to the eruption heard around the world in 1883, that event was so powerful that it destroyed 70 percent of the island around the mountain and is one of the most destructive volcanic events ever recorded .

The sound of the explosion was heard more than three thousand miles away and the shock wave it produced circled the entire planet four times. The eruption was attributed to the deaths of almost 35,000 people but, instead of being trapped in the flow pyroclastic, a large number of them were due to tsunamis that did not form It is certain how high the tsunamis reached at their peak, but it is likely that they were at least a hundred feet and potentially many times higher than when traveling through the open ocean are only present as a small wave and it is only when they make landfall. that their true size is seen unusually, however, those created by this eruption proved to be as deadly in the sea as on land.

Boats in the water, as far away as South Africa, were tossed violently by waves and several sank with the loss of its entire crew, the Indonesian town of Merak was completely destroyed by a wave estimated to be 150 feet high. height and several others suffered the same fate. Smaller waves were also detected on the other side of the world, including in Europe and you. I just have to wonder how catastrophic it would have been if it had happened today, when there are so many people living in coastal regions all over the planet. Number one in Lituya Bay, Alaska.

After all, you probably haven't heard of Lituya Bay in Alaska before. It is in a remote region of the state and very few people live near it; However, it was the location of the largest tsunami known in modern times and the event that took place there in 1958 forced a complete reevaluation of our understanding of the formation. of large waves began on July 9 when a magnitude 7.8 earthquake shook the good weather fault, triggering a landslide in which 40 million cubic meters of material that would have weighed around 90 million tons fell at the narrow entrance to the bay. The impact was reportedly heard up to 50 miles away and caused a massive displacement of water.

The resulting wave is believed to have been up to 1,720 feet high. The unique topography of the landscape is believed to have contributed to this, as the wave initially measured around 100 feet. but continues to grow in size as it travels along the lake. Additional research analyzing the lake bed has also found that there is evidence of much more sediment than expected, suggesting that the landslide may have released a second release of debris from a nearby glacier and released much more energy than previously thought. was previously thought. It's a good thing no one lived around the bay because a wave like this would have pulverized anything it came into contact with.

No other wave is known to have been anywhere near its size, but perhaps most worrying is something like this. It could easily happen again because it was caused by a landslide, there won't be any warning until it's too late, check out our wave playlist for more of the top 15 massive wave videos, sit back, relax and enjoy, watch all our best wave videos.
