Seismology: Earth's Tectonic Phenomenon Patterns

Decent Essays
For my “specialty,” I had seismology. Seismology is the branch of geology that studies earthquake behaviors. In this case, I had to deal with earthquakes and the movement of Earth’s tectonic plates. My plan was to look at where the map had different elevation patterns, so I can differentiate them into groups. I found 3 different categories, and identified them as Type 1, Type 2, and Type 3. My first category is a blue (X) to represent the boundaries outside the Pacific, South American, and Pacific Plate. I noticed that type 1 was found deeper as further into the plate. My second category is a red star to symbolize frontiers around the North American Plate and the outskirts of the African Plate. I classified the pattern as type 3, showing sporadic …show more content…
My group and I worked together well to collect the different data we received from the previous map. We were at a disadvantage because another group member and myself were assigned the same specialty; Seismology. Our first step was to look at the areas where the map is constant to make a grouping for sections on the plate boundary. Based on this method, we discovered four different type of formations from our legend. Our first type is seismology; which appears further from the plate. The second type, is volcanology, which presented as clusters. The third type; geography, starts deep below sea level then gradually rises. The last type is Geochronology, found on the Nazca plate; the closer you get to the land, the older the rock formation. Since the Nazca plate is a fairly simple plate, it was easy to make four different categories to combine our …show more content…
Which is an oceanic tectonic plate located in the eastern Pacific Ocean basin right off the west coast of South America. The never-ending subduction found along the Peru- Chile Trench in the Nazca Plate under the South American Plate is the sole reason for the Andean orogeny. The Nazca Plate is surrounded by the Pacific Plate on the west, and on the south the Antarctic Plate through the East Pacific Rise and the Chile Rise. Due to the movement of the Nazca plate over numerous hotspots, volcanic islands have been created sub-ducted under South America. Shallow earthquakes are caused by faults and the movements of the continental plates, these earthquakes have their focus near the surface of the earth. Because these types of earthquakes are of a large spread, they cause greater damage at the earth’s crust. Roughly 75% of the world’s energy released from earthquakes are from shallow ones. As for deep earthquakes, they occur in sub-ducting oceanic plates, moving beneath the continental plates. They happen with larger magnitudes, as a ton of energy is released by the collision of the plates. Geologists often use triangulation as a way of finding the locations of Earthquakes. Triangulation is a way of determining something 's location using different locations. The four different types of earthquake waves are P and S wave, Surface wave and the Rayleigh wave. The faster of the waves is known as the primary wave (P

    3. Surface waves: Primary and secondary waves affect the surface resulting in the generation of waves called surface waves. These waves are considered to be the most destructive waves. Volcanoes Plate movement can also cause another natural disaster called volcano. Under certain conditions, when plates are pushed or pulled together, volcanoes are created thus, both earthquakes and volcanoes tend to occur in the same place.…

    As tectonic plates grind against each other, they build up pressure, causing stress (Thompson 15). Stress on Earth is so great that they need a way to release all the pressure (Thompson 15). Stand-up energy will be released at the weakest point of Earth 's crust, which is on a fault (Thompson 15). The bursts of energy cause a section of the fault to break loose and the two halves bounce past each other (Thompson 16). The release of this burst of energy comes in waves of motion called seismic waves (Thompson 16).…

    Earthquakes may be caused by the movements of magma within a volcano’s chamber, but also vice versa with heavy seismic shifts cracking open into the inside of a nearby volcano. Both volcanoes and earthquakes can associated with tectonic plate movements as well. According to the National Oceanic and Atmospheric Association, “the Ring of Fire is a string of underwater volcanoes and earthquake sites around the edges of the Pacific Ocean.” Most of the Earth 's volcanoes and earthquakes occur around the Pacific Ring of Fire because that is the location of most of the Earth 's subduction zones. Subduction is when a tectonic plate sinks beneath another, and a subduction zone is the area in which subduction occurs. In this case, dense oceanic plates sink beneath the less dense continental plates.…

    There is something about volcanoes that genuinely terrifies people all around the world. Though the dangerous landforms have the power to destroy a civilization and force many to restart their lives over, many only know what they see. Do volcanoes have the power to cause destruction, terror, and earthquakes? Yes, but these landforms do so much more than that. Volcanoes have the power to create new landforms, fertilize soil, create minerals and stones, and contribute to global cooling.…

    Volcanoes Volcanoes are magnificent yet dangerous structures created by the forces of nature when Earth’s tectonic plates diverge and collide against each other letting the Earth vent out pent up gases, magma, rock, and ash. There are three types of volcanoes called Shield, Stratovolcanoes, and Cinder cones. Volcanoes are further labeled as active, dormant, or extinct depending on recent activity. The magma underneath the Earth’s mantle is responsible for the explosion and creation of volcanoes around the world. About 90 percent of all volcanoes on Earth are found in the Ring of Fire located in the Pacific Ocean.…

    At which point this geological region evidently experienced uplift. This uplift was due to a mountain building episode that occurred between the Silurian and the mid-metazoic. This event occurred when a continental crust collided with oceanic crust, at a convergent boundary, it causes crust to displace inland on the continental crust while the oceanic crust falls below the other plate via subduction. When subduction occurs the pressure from below causes volcanoes and mountains to form further inland. This would also explain why the rock formation in the Quaternary time period was a pyroclastic…

    By definition, an earthquake is a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth’s crust or volcanic action (dictionary.com). Earthquakes occur among many places on earth and to a variety of different degrees. Earthquakes are specifically common in the San Francisco Bay region in California. Scientists have made great strides in the process of learning about earthquakes and continue to do more work that will help them learn about earthquakes in the future. Earthquakes occur when two fault planes strike one another resulting in the shaking of the earth.…

    Characterize earthquake magnitudes The distribution of these earthquake sizes in a region generally follows the following distribution: log⁡〖λ_m 〗=a-bm (2.1) λ_m is the rate of earthquakes with magnitudes greater than m. Parameter a value indicates the overall rate of earthquakes in a region. Parameter b value indicates the relative ratio of small and large magnitudes (typical b values are approximately equal to 1). This equation results from the Gutenberg-Richter law because Gutenberg and Richter first studied observations of earthquake magnitudes. This equation can also lead to the cumulative distribution function (CDF) for the magnitudes of earthquakes. There is also some limit on the upper bound of earthquake magnitudes in specific region.…

    trembling or shaking of the ground is the result of the violent shifting of massive rocks underneath the Earth’s surface called tectonic plates (“My Big Book of Knowledge” 26). Earthquakes can happen on a very high scale, causing between 30,000 and 830,000 casualties during a single earthquake. Earthquakes can be much more dangerous than hurricanes as they can’t be predicted, but, all the same, there are many striking similarities between both. To begin with, both are formed in very different ways. An earthquake happens because of a sudden release of energy in the Earth’s crust that creates seismic waves.…

    The movement of earth's crust is capable of shifting huge volumes of water, then it unleashes great and powerful waves. Among nature's most powerful forces of destruction, these waves are called tsunamis. The Japanese term means "harbour waves". Tsunamis are a series of large ocean waves of extremely long wavelength and a period which is suddenly displaced on a massive scale by an underwater disturbance such as an earthquake occurring on or near the seabed or a volcanic eruption. Tsunamis hit the coastal regions approximately 10 times each year.…
