How Are Earthquakes Affected By Plate Tectonics

842 Words4 Pages

What are earthquakes? Earthquakes are the sudden, rapid shaking of the earth, caused by the breaking and shifting of rock as it releases pressure that has accumulated over a long time. So pretty much shaking movement of the earth’s surface. All earthquakes aren’t the same, they vary in size, magnitude and intensity. The magnitude and intensity of an earthquake is determined by the Richter Scale and the Mercalli Scale. Earthquakes are caused by the plate tectonics crashing into one another. Without the plate tectonics, there would be no continents, no large mountain ranges and Earth would be submerged to a depth several thousand feet. Most of the world’s sea creatures would be fine, but many humans cannot survive this. Tectonic plates produce …show more content…

Eschool Today states that these horrific disasters are formed when a vast amount of energy and pressure has built up from the tectonic plates. The movement from the tectonic plates causes immense tension in the plates and there is massive pressure on the fault lines. This intense pressure resulting from energy build up causes the fault lines to give away. Then plates move against, apart or over one another. Now there is an earthquake. Earthquakes sizes can be determined by a seismograph. A seismograph can detect strong earthquakes from anywhere in the world. An earthquake can also be measured by the Richter Scale, but it is hardly used anymore. The Richter scale has been replaced by the Moment Magnitude Scale, which is more accurate. There are seven major plate tectonics and each of them are under a continent or ocean. The different plates are called the African Plate, the Antarctic Plate, the Australian Plate, the Eurasian Plate, the North American Plate, the Pacific Plate and the South American Plate. Next, in the article, Why Earthquakes Are Shaking North Texas: Scientists Investigate Links to Disposal Wells, Sheyda Aboii and Terrence Henry state that more earthquakes are happening in my location (Texas) because of disposal wells being built. Before these wells were built, Texas hardly had any earthquakes, but as more wells are being built, more earthquakes are happening

- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of earth. Tectonic processes reshape continents and also cause earthquakes - Tectonic plates- plates caused by convection currents in the mantle that causes earthquakes. - Ocean basins form where continents crack and pull apart. - Magma – is molten rock

The asthenosphere is making convection currents. Since the convection currents are always moving it causes the asthenosphere to move and bend because it is ductile. When the asthenosphere moves which is under the tectonic plates it will cause an earthquake or more specifically the Alaskan Way

Earthquakes. They shake buildings, they wobble structures, they dismantle even the most stable construction. They leave people without homes, destroy possessions. The San Francisco earthquake in 1906 left at least half of the population homeless.

The two plates that moved were the North American tectonic plate and the Pacific tectonic plate. The plates moved about 15 feet, this is huge because the average movement of tectonic plates during an earthquake is only 2 inches. The earthquake only lasted a minute but it quickly destroyed the city. The earthquake

How the Science of earthquakes was started in North America after the California Earthquake of 1906 The California earthquake of April 18, 1906 is one of the most significant earth quakes of all time. The 7.9 magnitude earthquake ruptured the northernmost 477 kilometers of the San Andreas Fault from the northwest of San Juan Bautista to the triple Junction of Cape Mendocino. The earthquake caused severe damage with reports indicating that it caused more than 3,000 deaths and destroyed more than 28,000 buildings (Borcherdt, & Gibbs, 1976).

While the Salem Witch Trials, the topic of Arthur Miller’s play The Crucible, is one of the more famous examples of American witch hunts, many other witch hunts were equally as terrible, such as the Lavender Scare. The Crucible is a historical drama that begins with Reverend Parris finding his daughter, Betty, his niece, Abigail, and several other girls dancing in the forest. When Betty becomes very sick afterward, the townspeople begin to look to witchcraft as the answer, and Abigail begins accusing people of witchcraft. Similarly, The Lavender Scare involved the prosecution of queer people due to the short-sightedness of Americans from 1945-1960s. People during this time believed that members of the LGBTQ+ community could spread their homosexuality

little movement from the tectonic caused big things such as earthquake, but what exactly is San Andreas Fault? San Andreas fault is major fracture of the Earth’s crust in extreme western north America (Brittanica). San Andreas fault have caused so many earthquakes in U.S.A, causing many destruction, and causing lost of lifes. Now, What made Northridge Earthquake so destructive? While the Northridge earthquake was happening Californian people couldn’t predict it (u-s-history.com).

They have the same impact like secondary hazard. They are tsunamis, secondary hazard, that causes after the earthquake, tsunami had killed a lot of people and destroy area around there. The effect for Valdivia earthquake are too big so they’re traveled across to the Pacific Ocean and traveled along to the southern Chile, Hawaii, Philippine, Japan and etc, with the speed are over than 200 miles per hour. While the effect for Alaska is also big, that why this incident which is caused tsunami and massive landslides are also affect a lot in Canada to Hawaii.

Recently, on January 7th 2016, there was an earthquake caused by fracking, in Oklahoma, where earthquakes are rare. This particular quake was a 4.8 on the Richter Scale, which is the highest ever recorded. It occurred in the center of the state, was felt all over. Also, within the past week, there have been more than 20 quakes all over the state. in recent years, since 2011, earthquakes have occurred more and more often.

A report from U.S. Geological Survey “Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells,” This Hydraulic fracking fluid is being injected into the ground and is essentially liberating the faults allowing earthquakes to happen more frequently, causing damage across the states and most common in Oklahoma, Texas and

These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.

Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
