Earthquakes
The earth is a very unique place with very intense catastrophes that occur throughout its lifespan. Some of these catalysts have the ability to completely alter the earth in ways that no man made invention could do. Earthquakes are among those catastrophes that cause unimaginable amounts of damage in what seems like no time at all. Earthquakes are caused by a collision of two plates in the earth. The collision will then send seismic waves across the surface of the earth destroying anything in its path. When earthquakes occur in the ocean, the collision can create a fault in the earth 's floor. The pressure from the seismic waves, combined with the shifting of plates will typically causes tsunamis as well.

This quake was documented on 22 of May 1960 and was a magnitude of 9.2 by the U.S. Geological Survey and was said to be the largest earthquake of the 20th century (Lutgens, Tarbuck, & Tasa, 2015). The earthquake started off of the coast of Chile, and sent the seismic force inward toward the city of Valdivia. The fault where the plates collided to cause this earthquake was estimated to be anywhere from 560-620 miles long, and ran across the stretch of the Nazca …show more content…

Once the earthquake hit, 15 hours after, it created tsunamis, which swept over coastal areas of Hawaii. It destroyed buildings and facilities along the shoreline. The effects of the tsunami caused by this earthquake caused millions of dollars of damage to Hilo Bay on the main island in Hawaii (Fujii, & Satake, 2013). The force of the earthquake was large enough to force this tidal wave all the way across Hawaii and into the Japanese islands. The main island that was hit with the tsunami was the Japanese island of Honshu, the effect of the wave hit this island almost 22 hours after the original earthquake off of the shores of Chile. On the alternate side of the wave, off of Long Beach, California, boats and ships were greatly damaged however no deaths were recorded in this area. Although it is not confirmed, two days later a volcano by the name of Cordon-Caulle erupted in Los Lagos after 40 years of inactivity (Fujii, & Satake, 2013).. The effects of the earthquake are believed to be what has caused the eruption creating an even larger death

  • 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.

    Earthquakes, by Webster’s dictionary definition, are, “a shaking or trembling of the earth that is volcanic or tectonic in origin.” World Book Encyclopedia reports scientists believe that more than 8,000 earthquakes occur each day without causing damage. A little more than 1,000 each year are strong enough to be felt. Earthquakes occur in the general sense, anywhere on land. Other earthquakes go by different names, such as volcanic eruptions and tsunamis, large tidal wave storms that occur underwater, primarily in the Pacific Ocean.

  • 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.

  • The Tohoku Earthquake In Japan

    1793 Words  | 4 Pages

    TOHOKU, Japan, Friday, Mar. 11 -Yesterday, a 9.0 magnitude Earthquake struck the east of Tohoku, Japan. The epicentre of the earthquake was located approximately 72 km east of Tohoku (38.3 degrees North latitude and 142.4 degrees East longitude), or 130 km east of Sendai as shown by the X in figure 3 below. The focus of the earthquake was 24.4 km under the epicentre. The earthquake therefore caused a tsunami due to the displacing of water above the Pacific Plate. The earthquake and tsunami together have caused approximately 20,000 deaths, 6152 injuries and 2500 people missing. Approximately 90% of these deaths were by drowning. Approximately 140,000 people have been displaced and over 500,000 buildings and structures have been destroyed or damaged. The early warning system of Japan stopped many bullet trains, and many residents received texted warnings of the earthquake and tsunami on their mobile phones giving them time to evacuate. Figures 1 and 2 show exactly how destructive the tsunami caused by the Tohoku Earthquake was.

  • The Northridge California Earthquake

    Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...

  • Effects of the Great Kanto Earthquake in Japanese History

    1580 Words  | 4 Pages

    The Great Kanto Earthquake also known as the Tokyo-Yokohama Earthquake of 1923 hit the metropolitan area of Kanto on September 1st, 1923 around 11:58 pm. It was a 7.9 on the Richter magnitude scale, killing over one-hundred and forty thousand people due to its high magnitude and the time it happened. The earthquake struck around lunch time, when many Japanese people were at home cooking at their charcoal or gas fueled stoves. At the moment the earthquake hit, it knocked down buildings that caught flames from the stoves that fell over, enflaming the city. The fire was swept up and able to spread due to the gusts of wind that occurred for two days afterwards, resulting in firestorms. Charles Blauvelt experienced the ordeal of the fire describing the flames as “[covering] the whole city [as they] burned all day and night.” In addition to the firestorms and the earthquake itself, there was a shock because of all the fallen debris which triggered tsunamis to fill and flood Japanese cities. These tsunamis, that were about thirty feet tall, destroyed central Tokyo and immensely added to the death toll.

    It was known as the great Alaska earthquake. On March 27, 1964, an earthquake with a magnitude of 9.2 struck the Prince William Sound region of Alaska. This earthquake is the second largest earthquake ever recorded in the world, the first as a magnitude 9.2 in Chile in 1960. In other words, this earthquake released 10 million times more energy than the atomic bomb dropped on Hiroshima Japan. Equally important, this (Abby Lautt) earthquake produced landslides and caused catastrophic damage covering an area of 130,000 square kilometers, which is the entire state of Alaska, parts of Canada and Washington. The earthquake lasted approximately four minutes with eleven substantial after shock occurring over the next 24hrs causing damages in the amount of almost $400,000 and killed 131 people.

    Earthquakes happen about 20,000 times a year worldwide. They can destroy almost anything.In 2011, Japan had 9.1 magnitude earthquake, close to the highest magnitude of 9.2 in Alaska. They suffered tremendous damage from such a strong earthquake. The year before Haiti suffered from a 7.0 magnitude earthquake, still quite high compared to small tremors at magnitude 0-2. Japan recovered and rebuilt much faster than haiti did though. Haiti isn't even quite done recovering yet. The earthquakes had such different effects on the countries because of their economy, the condition of their people, and population rates.

    In Heinrich von Kleist’s, The Earthquake in Chile, illustrates the story of star-crossed lovers brought together through a natural disaster. The description of the earthquake presents itself as a scene from hell. The relation between the destructiveness of the earthquake and the image of hell of apocalyptic literature presents the end of the world for the people of Chile. Kleist uses imagery to portray post earthquake Chile as the Garden Eden, the presence of a pomegranate tree symbolizes the start a new life and foreshadows the inevitable end for Josepha and Jeronimo. By introducing a pomegranate tree , Kleist frames the effects of the earthquake as an opportunity for and altruistic community. The symbolism of the pomegranate tree in the “Garden of Eden” symbolizes fertility for the rebirth of the Chilean community. Heinrich von Kleist’s, The Earthquake in Chile, presents the destructiveness of an earthquake as a transition from the image of hell to an opportunity to rebuild the community.

    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.

  • Earthquakes Hazards And Disaster

    1192 Words  | 3 Pages

    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).
