The Great Chilean Earthquake An earthquake is the shaking of the earth by seismic waves radiating away from the disturbance, most commonly fault movement. The great Chilean earthquakes origin was of the coast of Chile at a subduction zone, referred to as a hot spot for seismic activity. A subduction zone is a region on the crust of the earth where two tectonics plate meet one another. The area where the two plates meet is called a plate boundary. When two plates meet at a subduction zone, they converge towards each other, and one these tectonic plates come into contact with each other, one bends and slides underneath another, resulting in one curving down to the mantle. In this circumstance when subduction is taking place the denser plate is the one that sinks beneath the other. On the earth’s surface there are two main types of crust; the oceanic and the continental. The continental isn’t as dense as the oceanic making it slide above while the oceanic subducts down, in a convection motion to recycle itself then be remade when it pushes itself up. The place the denser medium goes towards is the mantle that consists of molten rock and it accounts to 84% of earths volume. Subduction only takes effect when two plates of different density collide, for if two continental crusts converge and push together neither will subduct, so it will be like a car crash where the two mediums smash into each other but neither subducts, as an example of this event look to the Himalayas that were
Plate tectonics is a theory that Earth’s crust is broken up into plates that float along the mantle. The plates act like a broken egg shell around the yolk or mantle, outer core, and inner core. Scientist Alfred Wegener didn’t have a scientific reason to explain how the continents moved. These plates are moving very slowly and in a very, very, very long time, Earth will look different than what the continents look like now. The Nazca Plate is moving southeast and will cause a collision with the South American Plate.
The Valdivia Earthquake occurred on the 22nd of May 1960 in Valdivia, Chile. It is the most powerful earthquake ever recorded with a magnitude of 9.5. The earthquake resulted in many natural disasters not only in other parts of Chile but in other countries as well.
This earthquake left 2 million homeless and $600 million in damage this earthquake led to a tsunami 15 hours later a 35 foot wave smashed into hilo (the big island of hawaii) hawaii is more than 6 thousand miles away from chile. 1,600 homes were destroyed and 185 and more are dead ore missing. 1 day later a deadly 18 foot wave smashed into japan. this earthquake lasted for 11 minutes. this earthquake was big enough it rang the world for days like a bell. The earthquake hit at 7:11 pm approximately 100 miles (160 km) off the coast of Chile, parallel to the city of Valdivia. The shock is generally agreed to have had a magnitude of 9.5, though some studies alternately proposed that it may have been 9.4 or 9.6. A series of foreshocks the previous
What is an earthquake and why do they happen? : An earthquake is vibrating of the ground caused by the rapid breaking and motion of large parts of the earth’s rocky outermost crust. Earthquakes
Have you ever felt the strongest earthquake happen? Well, the people in Chile had. An earthquake is a sudden and violent shaking of the ground, causing great damage. The earthquake’s magnitude reached up to 9.5; a magnitude is the great size or extent of something. This earthquake was the strongest and most powerful earthquake to ever exist, and to be fully recorded.
The 2015 Illapel earthquake occurred 46 Km offshore from Illapel, Chile on September 16 with a moment magnitude of 8.3,and lasting three minutes. Several aftershocks of magnitude over 6 have taken place so far.The Chilean government reported 13 deaths and 6 missing.Another 34 people were injured.Illapel, an inland city of some 30,000 residents, was reported immediately to be without electricity or drinking water.Two days after the quake, about 90,000 people were still without electricity.
In the article there were many interviews about the victims of the earthquake. The earthquake killed thousands of people. When the earthquake occurred the people of Mexico could feel the ground shaking and were scared. They took cover and then saw all of the damage. The city hall collapsed during the earthquake as well. All of the natives were shocked to see the damage and did not have the money to repair. A lot of allies of Mexico are helping them get through the tragedy. The police are still searching for
Earthquakes are a common natural disaster that have a great impact on our population."A earthquake is the shaking of the earth surface, it releases energy in the lithosphere creating seismic waves"(The Science of earth). A seismic area refers to the frequency type and size of the quake. This is measured
Subduction zones are also where Earth’s deepest ocean trenches are located and where deep earthquakes happen. The trenches form because as one plate subducts under another, it is bent downward. Earthquakes occur as the two plates scrape against each other and as the subducting plate
An earthquake, as the Cambridge dictionary says, it’s a sudden movement of the earth’s surface, sometimes causing great damage. In this research paper I will be talking about the earthquakes in America that have caused the most damage economy wise in the past century.

Currently, Chile is experiencing very intense wild fires, and some cities are still trying to rebuild their lives after the earthquake in December. Amidst these natural disasters, Chile is also getting ready for its 2017 precedent election in November. Currently, most news reports claim that the left-wing party in Chile is being favored, but Chile is also experiencing a decrease in the citizens participation in voting. There are many theories about why this may be happening, and the most popular seems to be that the Chilean people are losing trust for their government. Because I will be in Chile during the semester that the election will take place, I feel like this will be most significant challenge between protests and speeches. There
Sediments had accumulated in the subduction zone so; here the oceanic plate was submerging. The hard layer of sediments was several kilometers thick above the plates. Many splay faults had been extending from the plate borders have been found in the stratum of the sediments.
The pieces that make up the crust and mantle are called tectonic plates. They’re always slowly moving, and they can slide past each other or even bump into one another. The edges of these pieces, or plates, are called plate boundaries. They have lots of faults, which are the surfaces where they slip past each other, and these faults are where most earthquakes happen.
An Earthquake is the shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. The sudden shaking of the ground that occurs when masses of rock change position below the Earth's surface is called an earthquake. The shifting masses send out shock waves that may be powerful enough to alter the surface of the Earth, thrusting up cliffs and opening great cracks in the ground.
