1: Introduction
Earthquakes are one of the most destructive natural disasters. They can cause many other natural disasters for example, tsunamis, avalanches or volcanic eruptions. Earthquakes occur when one tectonic plate collides with another.
There are 15 main different tectonic plates spread around the globe. Earthquakes can be recorded with seismometers. The magnitude of Richter is the most common scale. Earthquakes are movements of the Earth caused by the release of stress accumulated by geologic faults or by volcanic activity. In the last years, many scientists think that drilling for oil and gas (fracking) causes earthquakes too. There are three different types of earthquakes that will be defined in this discussion.

Volcanoes:
When violent volcanic eruptions happen, impulsive disturbances are susceptible of generating an Earthquake or a Tsunami. Tsunamis generated by Volcanoes are infrequently.

Meteorite impact:
Asteroids and meteors colliding with earth are really rare but the “scientists realize that if these celestial bodies should strike the ocean, a large volume of water would undoubtedly be displaced to cause a tsunami.” Meteor impact is the less common factor that could generate a tsunami. Tsunami generated by meteoric impacts is very rare.

Landslides:
Icefalls, rock falls and underwater slumps or landslides could move water that could cause a tsunami. It is rather rare that a landslide cause a tsunami.

Earthquakes:
Tectonically movements of plates that generate tsunami can create a fault that could cause a Tsunami. Earthquakes are the most common generator of tsunamis.

The tallest tsunami ever recorded was 1,720 feet tall, which is approximately the height of one tower of the World Trade Center. This occurred in 1958 when a landslide fell into a fjord in Alaska.

    Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...

  • The Cascadia Earthquake: A Disaster that Could Happen

    2015 Words  | 5 Pages

    The scenario mentioned above was based on the rupture located along the Cascadia fault line. This fault system runs from Northern California to Vancouver Island about 700 miles off the shore (FOX5). Scientists use to believe that the San Andreas Fault was where a large earthquake tsunami would originate, but recently their attention has shifted to the Cascadia subduction zone which is now said to be much more dangerous than previously thought (FOX5). Recent earthquake events have added even more tension and possibility for a large-scale tsunami. On March 10, 2014, a 6.8 magnitude earthquake struck off the coast of Northern California, which put a lot of stress on the Mendocino Triple Junction (Davidson). The Mendocino Triple Junction is where three tectonic plates collide, and is very unstable (Davidson). This junction has all this built up pressure and is about ready to explode. Scientists believe that this junction will be the origin of a tear along the 680-mile long Cascadia Subduction Zone. (Davidson). The disaster that follows will be considered the United State’s largest modern-day earthquake.

    Tsunamis can go the same speed as a jetliner and that massive wave can out run the fastest runner. When there is a lot of waves at once, or the water goes back that is a sign that a tsunami is coming. If that tsunami is far then people need to get to the tallest and strongest building there is in the city that way they are safe and helicopter can pick them up. Tsunamis can wipe out an entire city or 1/4 of the country. Tsunamis can last up to an hour, or more.

  • The Cause Of The Sumatra Tsunami

    1424 Words  | 3 Pages

    A tsunami is a series of waves “created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite” (ready.gov). Tsunami waves are quite different from normal waves. Once a tsunami is set in motion there is no way to really “prevent” it fully, or to stop such an event. Precautionary steps can be taken, such as in Japan where a sea wall was built to protect people and property. However, this was a futile attempt since in 2011 a tsunami was able to surge over the wall, with the water building up and rushing over the top. The lesson learned is that one should not

    Floods and washing away of homes was caused by the rupture of the Fujinuma irrigation dam in Sukagawa. The flooding of the dam caused the drowning of many people and was a factor in the 90% deaths by drowning. Soil liquefaction is caused by applied strength from an earthquake and is where soil behaves as if it is liquid, and at a water purification centre in Tohoku, the soil sank 1 metre. Many coastal towns and cities were destroyed as a result of the tsunami that followed the initial ground shaking. The tsunami even spread to locations across the world such as Hawaii, Ecuador, Chile, Peru, Antarctica, California, Oregon and the Galapagos Islands. However, there were no deaths due to these

  • The Symlar San Fernando Valley Earthquake of 1971

    1771 Words  | 4 Pages

    Earthquakes are best described as a shaking or vibration of the ground caused by breaking of rock. Sometimes they are very strong and other times you would hardly notice them. This shaking occurs when stress that builds up in the crust is suddenly released as the crust breaks free and/or slides against the other pieces of crust. Earthquakes may also be thought of as the breaking of a popsicle stick by applying pressure to both ends at the same time. Should you try this experiment , you will feel the pressure build up as you apply more force until the stick snaps. When the stick snaps you will feel an instant of pain at your fingers as the stress reduces and energy waves move throughout the stick. When the earth's crust is placed under similar types of stress, binding as the stress builds, it will also snap and release the energy into the surrounding rocks, 'ooch'. Thinking about earthquakes will become more clear if you try another experiment.

    Psychology is the study of the mind and the behavior of mammals. Geology is a science that deals with the history of the earth and its life, recorded in rocks. The earth is consistently moving its tectonic plates. Therefore, there may be over 100 earthquakes a day; most of these earthquakes go unnoticed by humans on the crust of the earth. Other earthquakes for example, the one in 2011 located in Japan and the Loma Prieta earthquake of 1989 (Earth- Marshak). Unfortunately, many people died in horrific ways during these deadly earthquakes, leaving thousands diagnosed with psychological disorders such as, Posttraumatic Stress Disorder and Specific Phobias directly related to the natural environment of the earth.

    While the early warning saved thousands of people, the Japan’s Meteorological Agency underestimated this earthquake as the subduction zone of Japan should not produce the magnitude 9.0 quake (Oskin, 2013a). The Tohoku Earthquake and its tsunami approximately killed 16 thousand people, injured 6 thousand people and around 3 thousand people were missing. Most people died from drowning. Around 300 thousand buildings, 4000 roads, 78 bridges, and many more were affected by the earthquake, tsunami, and fires from leaking oils and gas. Electricity, telecommunication, and railways were severely damaged. The debris of 25 million tons was generated and carried out to the sea by water (BBC News, 2012). The country’s authorities estimated more than 309 billion US dollars of damages. Landslides occurred in Miyagi and liquefaction in Chiba, Tokyo, Odaiba, and Urayasu (USGS, 2013). Furthermore, the tsunami destroyed protective tsunami seawalls. Approximately 217 square miles of Japan covered in water (Oskin,

    As the tectonic plates slide over each other, they cause earthquakes. Earthquakes produce various damaging effects, this includes damage to structures of buildings, bridges and other standing formations which then result in injuries and people getting killed, wildlife getting disrupted as well as humans. An earthquake can affect the earth as it’s easier to let the lava come out of the earth. Tsunamis- Can cause financial problems such as home loss, job loss which will then result in being homeless, loss of crops and food supplies which causes a lot of harm to us ‘humans’. A tsunami is a series of waves that send surges of water that can travel thousands of miles.

    Earthquakes are vibrations felt at the surface of the earth which are caused by disturbances of the energy in the earth's interior. These vibrations are known as seismic waves. (Skinner Robinson McVerry 1) There are different type sof seisimc waves such as Primary (P) waves, whcih travel the fastest, Secondary (S) waves which cause the earth to vibrate vertically, Surface (L) waves. P and S waves are "affected by changes in the density and the rigidity of the materials through which they pass." (Columbia Encyclopedia) Earthquakes vary in their intensity and duration. Often times they are strong enough to cause massive destriction. Tall buildings often suffer as a result of these natural disasters. In recent years this has become a larger and larger threat with both the number of large buildings, and their number of occupants increasing. In an effort to try to minimize the damage caused by earthquakes many some engineers focus primarily on designing and constructing earthquake resistant buildings. Earthquake engineers have gathered much of their information from analyzing past earthquakes, and learning which buildings can and can't withstand the tremors. The goals of these engineers is to design buildings that can withstand moderate earthquakes and obtain minimal damage, and that the buildings will not collapse lowering the probability of human deaths.

  • Earthquake in Japan

    726 Words  | 2 Pages

    There was a multitude of causes of the disaster in Japan. The first cause was a 9.0 magnitude earthquake that occurred off the coast of Japan. Japan is located in “The Ring of Fire,” an area in the Pacific Ocean that has multiple faults and earthquakes (Pedersen 13). Tectonic plates shifted off the North Pacific coast of Japan and created a massive earthquake. The next cause was a thirty-three foot wall of water that swept over cities and farmland in Japan (Branigan 2). Martin Fackler, a journalist, stated, “The quake churned up a devastating tsunami” (Fackler 3). The tsunami reached speeds of 497 miles per hour while approaching Japan (Fackler 3). The third and final reason of the disaster was that the cooling systems at multiple nuclear power plants failed. At Fukushima, a nuclear power plant in Sendai, Japan, the radioactive rods began to overheat due to the absence of water, which cools it. Explosions occurred at three of the reactors, which spewed radiation into the air (“Comparing nuclear power plant crises”). In conclusion, the earthquake, tsunami, and nuclear power plant issues were the causes of the disaster in Japan, but they also had a myriad of effects.

    Earthquakes belong to the class of most disastrous natural hazards. They result in unexpected and tremendous earth movements. These movements results from dissemination of an enormous amount of intense energy in form of seismic waves which are detected by use of seismograms. The impact of earthquakes leaves behind several landmarks including: destruction of property, extensive disruption of services like sewer and water lines, loss of life, and causes instability in both economic and social components of the affected nation (Webcache 2).
