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.…
Volcanic dust exploded in the upper atmosphere, affecting incoming solar radiation and the Earth's climate for several years. This outbreak led to a series of large tsunami waves, some with a height of almost 40 meters (over 120 feet) above sea level, killing more than 36,000 people in coastal towns and villages along the Straits of Probe islands of Java and Sumatra. Tsunami waves were recorded and observed throughout the Indian Ocean, the…
Earthquakes beneath the ocean floor, volcanic eruptions and anything that displace large amount of water can cause tsunami.…
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.…
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.…
As a member of the government Disaster Management Task Force, a geographical report has been required to be written which analyses the impact of two natural disasters and evaluates which was the most severe. The two chosen natural disasters includes the 2011 Japanese tsunami/earthquake and the 2010 Haiti earthquake. Disaster 1 – Japanese Tsunami and Earthquake On Friday the 11th of March 2011, a magnitude 9.0 Earthquake struck coastal waters, along a subduction zone, surrounding Japanese islands. At the time of the Earthquake, no one expected what was about to occur, one of the most devastating tsunamis to have ever hit Japan.…
The Earth is 71% oceans. There can be no surprise then that the oceans affects human existence every day. Oceans are a source of economy, leisure, and sustenance. They are also a powerful force to be respected and studied. When the oceans unleash their power and volume in the form of tsunamis the effects are almost always devastating for mankind. These events have changed the course of life on earth more than once. Tsunamis can be triggered by bolide impacts and earthquakes as well as underwater rockslides. Tsunamis have caused mass extinction events, led to significant numbers of human casualties, and produced crippling economic damage. In my lifetime I have witnessed, from afar, the effects of two different tsunamis.…
Lahars travel in the valley bottoms much like pyroclastic flows and kill by suffocation or flooding. Tsunamis can be extremely dangerous also. Tsunamis are giant waves generated either by an earthquake or entire flank of a volcano crashing into to the water. Many tsunamis occur without notice and many die from flooding on the coastline. Non-explosive eruptions can also present dangers.…
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.…
One physical factor of an earthquake is the possibility of lowland coastal areas being open to tsunami threats. The Boxing Day Tsunami of 2004, claimed 300,000 people due to the earthquake of magnitude 9.0 triggering a slip in the…
