Essay about Tsunami Hazards And Mitigation In Canada

Both of these events can take out complete cities and coastlines destroying everything in their paths. The destruction ranges from ant piles to giant buildings. These catastrophic events normally leave places looking like flat, abandoned wastelands. While the tsunamis or hurricanes are happening, land can be completely submerged in water by up to around twenty feet. As fast as the water rushes onto land, it leaves just as fast and with the same amount of destruction. A lot of losses happen in this instance when they are dragged out into the

Tsunamis are caused by earthquakes underneath the ocean, which can results in gigantic waves that cause devastation and change the Earth’s surface by causing radiation and causing underwater landslides. In the article “Is Santa Catalina Island Sinking or Rising?” it describes how an effect of tsunamis. It states, “A tsunami could have struck the coast from Catalina when the underwater landslide occured” (Los Angeles Times 2). Therefore, tsunamis can strike coasts and can create landslides underwater, changing the ocean floor by creating caves and canyons. Also, tsunamis can wear away beaches. When giant waves crash into coasts of masses of land, they can wear away the coast. Finally, tsunamis can cause radiation. In the article “Dangerous Tsunami Threat off U.S. West Coast,” it explains, “It [the tsunami] also damaged a nuclear power plant, causing a meltdown and spreading dangerous radiation in the area” (Los Angeles Times). Consequently, tsunamis can destroy and interfere with human made buildings which may contain toxic gases which may be released into the air and cause damage the environment. Incidentally, damaging the environment can lead to killing plant and animal life, and the Earth in that area could potentially become barren and

Throughout this unit, the Science in Practice class has been learning about natural disasters and the impact it has on humans and environment. The natural disaster that will be discussed in this report is the Boxing Day Tsunami, which occurred on the 26th of December, 2004. The tsunami took place in the Indian Ocean. Due to, two tectonics plates, the Indo-Australian plate and the Eurasian plate colliding, causing an underwater earthquake. Due to this awful disaster, people were killed, injured, diagnosed with diseases, homes and businesses were destroyed, the environment damaged.

Tsunamis occur when an earthquake happens in the ocean and the energy goes to the water creating huge waves. Tsunamis are very dangerous they can be so strong that they wash away the city, harm thousands, and cause hundreds of thousands to billions of dollars in damage. “A giant tsunami along the West Coast would wash away coastal towns, destroy U.S. Highway 101 and cause $70 billion in damage. More than 100 bridges would be lost, power lines toppled and coastal towns isolated. Residents would have as few as 15 minutes’ notice to flee to higher ground, and as many as 10,000 would die” (Dangerous tsunami threat off U.S. West Coast). This shows what kind of damage this geo-process can

The tsunami waves reached heights up to 128 feet at Miyako city and traveled inland as far as six miles. A tsunami is a series of large sea waves caused by a large displacement of water. The tsunami flooded an estimated area of approximately 217 square miles in Japan. The massive waves destroyed large three-story buildings where many people seeked for safety. Within hours of the first tsunami hit Hawaii and set off multiple warning to Canada, Alaska, South America, the United States, the Oregon coast, and the Pacific.

All along the coast of Central America the tsunami was observed. (February 4, 1965, Alaska Earthquake, Rat Islands, Magnitude 8.7) This earthquake was recorded at a magnitude 8.7 and caused a big tsunami of over 10 m on Shemya Island. It barely caused any damage, though. Just two months after the initial shock, an aftershock earthquake at a magnitude of 7.6 hit the same area. (March 28, 2005, Sumatra Earthquake aka Nias Earthquake) Just off the coast of Sumatra, Indonesia, was a devastating earthquake that killed 1,300 people. A majority of the devastation occurred on the island of Nias. The massive earthquake sparked a panic around countries along the Indian Ocean because there was a massive tsunami just three months earlier in December. ( August 15, 1950, Assam, Tibet Earthquake, Magnitude 8.6) There were at least 780 people who died in this 8.6 magnitude earthquake. Many buildings completely collapsed in areas of Eastern Tibet. Landslides and ground cracks/fractures ended up washing away and entire village. The village of Yedong collapsed into the Yarlung Zangbo River and literally washed

Tsunamis occur when there is sudden movement in an extensive body of water such as earthquakes, landslides on the sea floor, major volcanic eruptions or meteorite impacts. The most common source of a tsunami is earthquakes, which are another type of geomorphic hazard that is caused by the friction and stress that tectonic plates put on each other. Tsunamis primarily occur in coastal or island regions where there is a tectonic border or what is known as the ring of fire. As shown in the diagram below the ring of fire is located along the coastal and island regions of the world.As a result of the Pacific Plate diving beneath the Eurasian plate, on March 11, 2011, there were 2 geomorphic hazards, a magnitude-9 earthquake struck north Japan, which caused a deadly tsunami that reached heights of 39 meters. The destructive dilemma was dubbed ‘The Great Sendai Disaster’. The earthquake was caused by multiple centuries of stress on the tectonic plates surrounding the island. The earthquake caused a tsunami that reached the height of 39 meters (128 feet). Japanese scientists had previously discovered that there was another tsunami just like the one in 2011 that took place in 869 AD. But their warning was unhindered. The tsunami, which occurred in 869 AD, was caused by the same tectonic fault as the 2011 tsunami. The epicenter of the earthquake was off the northeast cost of Japan leading to a devastating tsunami that killed many and left many wishing they were. The massive earthquake caused an upward wave that headed towards the city of Sendai. Researches have recently uncovered a thin layer of clay that lubricated the fault zone causing the deadly tectonic slip, thus creating a tsunami that could wipe out an entire city as it did in 2011.The aftermath of the 2011 tsunami and earthquake was not pretty; it caused many deaths, injuries, traumas, financial difficulties, destruction of property, health bills and the destruction of the landscape as a whole. The natural disaster caused nearly 16,000 casualties and there are an estimated 2,500 people still reported missing. Although drowning caused most deaths others include, crushed by debris, suicide and diseases caused by nuclear radiation (cancer) spilled from nuclear

The word tsunami comes from a Japanese word meaning “Long harbor waives”. Tsunami is much known and very common in Japan because thousands of Japanese have been killed and some suffered in recent centuries. Tsunami waves generally speaking cause a lot of damages such as, killing people, destroying building, and costing million of dollars. Moreover, a tsunami is a series of great sea waves caused by an underwater earthquake, landslide, or volcanic eruption. The 2004 Indian Ocean earthquake that is located on epicenter off the west coast of Sumatra, Indonesia, is actually one of the worst disasters in the history of Indian Ocean that generated by the most powerful 9.0 magnitude earthquake. An aggressive

How does an earthquake cause a tsunami? We live on Earths crust. The earths crust is broken up into many parts and fit together like a jigsaw puzzle. These puzzle pieces are called “tectonic plates” At times these plates move towards one another and push together. At other times they move apart away from each other. The plates usually move slowly so we do not feel the movement beneath us. There are times however that we do feel the movements. These movements that we feel are called earthquakes as they shake the ground beneath us. There are two kinds of plates one is referred to as the “continental plate” and the other is called the “oceanic plate”. Just as their names imply the plates that lie under the continents are continental plates and those that lie under the ocean are “oceanic plates”. As we have learned in class many of the worlds earthquakes occur in what is called the ring of fire. The ring of fire is a vast area surrounding the Pacific Ocean. The edges of some of Earths tectonic plates meet in this area. Since the plates meet up there they can bump into each other. They can also move away or slide past one another. When this happens it can cause earthquakes and volcanic eruptions. Another factor in this formula for earthquakes are something called faults. Faults are large fractures in the Earths crust. These fractures are found at the edges of the tectonic plates. This is where most earthquakes happen. When an

An average of two tsunamis occur every year through the world that damages the land nearest to it. Also on average every fifteen years a destructive ocean-wide tsunami occurs.

The U.S. west coast is very vulnerable to tsunamis. If a big quake hits Oregon’s fault, then it can generate tsunami waves up to 98 ft high. A tsunami in this region can threaten lives and damage the area from California to Alaska. Future tsunamis in the Cascadian Subduction Zone off the Pacific Northwest are possible.

Once the tsunami finally reaches the coast, a tsunami may be seen as a falling tide or series of waves with a towering height of thirty meters. Before a tsunami wave hits, you’ll see that the water in the ocean is moving away, which means you will be able to see the ocean floor. It is most likely that the first tsunami wave is small and not big like everyone expects the first wave to be, and more waves each a different size arrive at the coast every ten to sixty minutes. A fun fact about tsunamis is that the tsunami waves can go faster than how the average human runs and can easily drown and kill you. Dangers from tsunamis can still happen for hours after the first tsunami wave arrived at the coast. Tsunamis are not like normal waves, what normal waves do is curl up for a while and then break and from what i know tsunamis do not do that therefore tsunamis are not like normal waves you see at a lake or in the ocean. Places that have been hit by the gigantic tsunami waves like coast may wear away into nothing. Just a single tsunami can cause flooding in hundreds of meters inland. Tsunamis are so powerful that they are able to crush buildings and houses and kill millions of people. Tsunamis have

The tsunami in Thailand that occurred on December 26, 2004, was by far the largest tsunami catastrophe in human history. It was triggered by a magnitude 9.1-9.3 earthquake along the Indian-Australian seduction zone off the northern coast of Sumatra. The tsunami waves traveled primarily in the east to west direction and caused major damage along the coasts of southern Thailand. Unpredictably, it was a violent earthquake beneath the sea that initiated the massive waves and struck more than a dozen countries in Southern Asia. It also destroyed thousands of miles of coastline and even submerged entire islands permanently.

Enormous forces that had been building up deep within the earth for hundreds or perhaps thousands of years were suddenly released on December 26, 2004, unleashing the energy of 475,000 kilotons of TNT or 23,000 Hiroshima-sized atomic bombs. This event would come to be known as the 2004 Indian Ocean Tsunami, and it would result in a death toll of 283,000, the deadliest tsunami in history. This report examines information surrounding how nature generates such a deadly phenomenon and its aftermath.

Tsunamis are caused by underwater earthquakes that displaces a large amount of water. The December 26, 2004 earthquake caused a deadly tsunami that is one of the most destructive tsunamis to ever happen. The 9.1-9.3 earthquake lasted for ten minutes and caused a fault line that stretched 750 miles to move up 40 feet. This movement of the earth pushed boulders
