Purpose: To investigate tsunamis Introduction:I have always been fascinated by tsunamis. I have to say that when I vacationed in Hawaii and snorkeled in the Pacific Ocean, I did give a fleeting thought to tsunamis. In the last activity, I mentioned that the characteristics and behaviors of waves that you learned from the video could be applied to other waves. As you complete this activity, I want you to think about the similarities between the rogue tsunamis and the common waves we have studied.Materials:none Procedure: 1. Answer the question based on your exploration on the tsunami website. 2. Submit the assignment according to the directions below.…
The earthquake occurred at a relatively shallow depth at 20miles below the surface of the Pacific Ocean. This, combined with the high magnitude, caused the tsunami.…
As early as 426 B.C.[->1] the Greek[->2] historian Thucydides[->3] inquired in his book History of the Peloponnesian War[->4] about the causes of tsunami, and was the first to argue that ocean earthquakes must be the cause.[5]HYPERLINK \l "cite_note-Smid.2C_T._C._103f.-5"[6]…
2)The Largest and most dangerous of oceanic waves is called tsunami or tidal waves. It’s wave could reach up to thousands of feet tall. 3)Tsunami is word originated from japan, and it’s equivalent in English is called “seismic sea waves.” There are many factors causing Tsunami. Most tsunamis that has…
1. A tsunami is made up of a series of traveling ocean waves of extremely long wavelength.…
A century ago, August 26, 1883, the island of Krakatau (Krakatoa) in Indonesia, the volcano exploded with devastating fury. The eruption was one of the most catastrophic natural disasters in history. The effects were experienced on a global scale. Fine ash from the eruption were carried by winds exceeding as far away as New York level. The explosion was heard over 3000 miles away.…
Earthquakes beneath the ocean floor, volcanic eruptions and anything that displace large amount of water can cause tsunami.…
This electronic source provided me with basic tsunami information. I believe that it is important to have as much information as possible about my topic, so that I am able to get the most out of my project and understand it to the fullest.…
The earthquake caused the Indonesian plate to suddenly jolt upwards at least 5metres. The sudden movement of the plate under the sea caused the giant wave called a tsunami (5-40metres high).…
Tsunami- powerful seismic sea wave that begins over an ocean floor earthquake can reach 30 minutes height when approaching land and can use destruction in coastal areas.…
What are tsunamis, and how can we decrease deaths among the human population? Tsunamis are created when underwater tectonic plates rub up against each other creating potential energy and then when they shift, the potential energy turns into kinetic energy which create a very fast wave. Geoscience helps us to better understand them through many ways. Once a tsunami starts, they won’t stop because of all the energy but there are ways to warn people about them through the uses of geoscience. First, geoscientists can predict when and where a tsunami will be formed based on things like earthquake information, detection buoys, tide gauges, etc. these specific tools allow geoscientists to know when to warn the public to evacuate because of tsunamis.…
This is caused by shallow-focus underwater earthquake; volcanic eruption and large land slide into the sea. The displacement of the water becomes the giant sea wave and they normally have a long wavelength over 100m and low wave height when they are still in the open ocean. When it approaches shallower water near the shoreline the speed and the height increases and it can reach 700km/h. tsunami is one of the most deadly seismic hazards can cause significant damage to buildings and infrastructure. On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami. It killed over 15000 people and the total cost of the disaster was over $300billion and Japan is still recovering today.…
The first of these occurred in the Indian Ocean Tsunami on December 26, 2004. According to the U.S. Geologic Survey, that tsunami was caused by a megathrust earthquake on “on the interface of the India and Burma plates and was cause by the release of stresses that develop as the India plate subducts beneath the overriding Burma plate” (USGS). National Geographic reported that the magnitude 9.0 earthquake generated as much energy as “23,000 Hiroshima-type atomic bombs” (NatGeo). This tectonic event caused tsunami waves that traveled thousands of miles, impacted 11 countries on the Indian Ocean and killed more than 250,000 people. One of the primary contributors to the tsunami death toll was a complete lack of any tsunami warning system in the Indian Ocean. In an article written shortly after the tsunami Waverly Person from the U.S. Geology Survey explained that, in addition to the lack of any sort of warning systems was the inexperience of the inhabitants in the affected countries which caused the staggering death toll. The inhabitants had never learned any of the warning signs, like a swiftly receding shoreline, because Indian Ocean tsunamis are very rare. In the years that have…
The Pacific Ocean is home of the “Ring of Fire.” The Ring of Fire is “a geologically active area where tectonic shifts make volcanoes and earthquakes common.” (National Geographic) These volcanoes were all formed due to something called subduction. Subduction is what happens when the plates hit, the land from one shift under the other, moving kind of like a conveyor belt. Where the plate moves and bends under the other plate, this creates a trench. Trenches are all over the Pacific Ocean. Due to the activeness of the Ring of Fire, about 80% of all tsunamis in the world occur in the Pacific Ocean. A tsunami produces large waves that can be very destructive to the land around it. These occur after a deep water earthquake. With more research, we should be able to better predict this activity and be better prepared on land for large tsunamis.…
A total of 30,828 landslides were triggered from the earthquake with 29 700 000 m3 of dirt being displaced (Xu et al., 2014). The earthquake also trigged a tsunami, with waves reaching 3m in height that destroyed several buildings and killed 3 people (Dell’Amore et al., 2010). The tsunami was unexpected due to the type of earthquake that had occurred. The earthquake was a strike slip earthquake which means the plates slipped horizontally against one another, which normally wouldn’t cause a tsunami due to there being no vertical movement of the plates, which is needed to create tsunamis. A current theory for the cause of the tsunami is multiple underwater landslides (Lovett, 2010).…
