1960: The First Earthquake In Chile

This lab uses earthquake data to construct profiles of two convergent boundaries: the Tonga Trench and the Peru-Chile Trench. Where two tectonic plates converge, if one or both of the plates is an oceanic lithosphere, a subduction zone will form. When crust is formed at a mid-ocean ridge, it is hot and buoyant meaning it has a low density. As it spreads away from the ridge and cools and contracts, or becomes denser, it is able to sink into the hotter underlying mantle. When two oceanic plates collide, the younger of the two plates, because it is less dense will ride over the edge of the older plate. The density of the

Before the quake hit the day before, there were a series of shocks that tipped off to people of Chile that something was coming. The day that the earthquake hit, it was a rated a 9.5 on the Richter Scale. The intensity of this caused thousands of buildings to be destroyed and 2,000,000 people left homeless. The population of the city had greatly decreased and the city also needed to pay for the damage to be repaired. It would be 800 million American dollars to complete the cleanup and repairs of the city almost completely. This earthquake was called “The Great Chilean Earthquake” because of the total destruction and because of the expansion of it where other countries received the aftershocks and effects. Japan had received a tsunami a day later, killing 138 people and leaving 1600 homes destroyed. Japan was left to pay 34 million dollars for damage

On August 24, 2014 a magnitude 6.0 earthquake occurred in and around the city of Napa, CA. The earthquake killed one person and injured over 150 people. And these people were treated at Queen of the Valley Medical Center in Napa [1]. More and more earthquakes occurred on this earth. So this grasps people’s attention.

The first major earthquake in this series was in December 1811 where the center of the earthquake was said to be started in northeast Arkansas; the people of Arkansas were the first to be shake. How did all this start? Earthquakes start when rock beneath the earth’s surface shifts in a swift and sudden way. I believe we see the earth changing overtime, but its overtime where as an earthquake is not. An earthquake is under the surface and we only see the effects of one. How do we know the New Madrid Earthquake occurred? It’s a tough question, but there’s enough documentation at our fingertips to answer the question. Many of the people that lived during the earthquake shared their experience, Crist wasn’t the only one. And that’s how we can say it’s

The right figure gives a more specific visualization of the Juan de Fuca plate currently been forced to slip under the North American plate in an area known as the Cascadia Subduction Zone. Along the boundary of these two plates, a section has become locked yet they are still moving toward each other. As a result, stress has accumulated for centuries and when that stress relieved, it will cause the largest and most powerful earthquake called a megathrust earthquake of magnitude 9.0 or higher. The last earthquake which was caused by the relieved of this stress with similar magnitude happened in 1700. The scientists were able to determine this date through sediment samples that indicated the coast’s seismic past, taken from the sea floor off the coast of Vancouver Island. Therefore, scientist were able to outline that earthquakes occur every 500 to 1000 years.The risk for a possible megathrust earthquake to happen is increasing and it is coming faster than predicted because the stress hasn’t been released recently and the Juan de Fuca and the North American Plates are constantly moving. Right now, Vancouver Island has been tilted higher and squeezed by a few centimetres eastward every year. In the next 50 years, when the strain released, an earthquake called the “Big One” will rip down the west coast from British Columbia to northern California,

Northern California. High intensity shaking was felt stretching from Salinas Valley to Eureka on the North Coast. The San Francisco earthquake of 1906 was one of the worst and most fatal earthquakes in both California’s and the United States’ history.

One of the most significant earthquakes to hit the San Fernando Valley in the past was the 1971 San Fernando/ Sylmar earthquake. On February 9, 1971 at about 6 o’clock the cities of San Fernando and Sylmar experienced an earthquake that ruptured along the Sierra Madre Fault Zone (Oakeshott, Gordon B). The epicenter of this earthquake was reported to be in the San Gabriel Valley Mountains above the valley. The citizens of both cities felt tremendous shaking. The magnitude of the earthquake was measured as a 6.6 on the Richter scale and the shaking had the intensity of a level 11 (extreme) on the Modified Mercalli system (U.S. Geological Survey). The shaking of this 6.6 magnitude earthquake lasted about 12 seconds with a very strong ground motion. The source of this faulting was located about five miles to the north of the San Fernando valley. The surface faulting of this earthquake was reported to be seen along the surface of the San Fernando fault zone from a point south of Sylmar, the faulting stretched 6 miles more as far as east to the little Tujunga Canyon, also more surface faulting was reported more east as well. In total the maximum surface rupture was 12 miles and the amount of slip was about 6 feet (U.S. Geological Survey). The type of fault scientist label this earthquake to be was an oblique-slip or also known as a thrust. The depth of this earthquake was 13km (8.1 mi) and the peak acceleration was when it reached the Pacoima dam having the speed of 1.25g (U.S.

In what season did the earthquake of 62 CE occur? The earthquake of 62 CE occurred around noon on a winter’s day.

This earthquake occurred on July 27th, 1976 northern eastern part of China in Tangshan. The earthquake had a magnitude of 7.5, but there was a major aftershock 15 hours later. The actual number of people dead was never really confirmed, but people say that over 244,000 people were killed.

These earthquakes were followed on Sunday, November 1, 1755, by a cataclysmic shock and tsunami that killed an estimated 70,000 people, leveling the city of Lisbon, Portugal, while many of its residents were in church. This event marks the beginning of the modern era of seismology, prompting numerous studies into the effects, locations, and timing of earthquakes.

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

In both articles devastating earthquakes occurred. Both ended up taking many lives with them. The earthquake in Nepal killed over 3,000 people, and the earthquake in Chile killed around 10 people and caused over 1 million to evacuate. The magnitudes were very close, Nepal: 7.8, Chile: 8.3. There were more casualties in Nepal because the building there aren’t reinforced to protect from natural disasters. However, there were still casualties in Chile because some of the houses were reinforced but not very well or the houses and building could be located in areas where the earthquake was more powerful. Buildings still crumbled in Chile but thankfully there weren’t very many casualties. Both of the quakes also had powerful aftershocks. In Chile

An 8.8 Richter scale earthquake hits the central-south region of Chile. Talca is among the most hardly hit cities, following Concepcion and Constitución. Around 50% of the city centre infrastructure results seriously damaged, especially old adobe houses. Among the affected buildings, institutional, historical and civic amenities are left at the brink of destruction.

On the 22nd of May 1960, the world’s largest earthquake which was documented occurred very close to Valdivia, Chile. The earthquake struck with a force of 9.5 magnitude. The earthquake pushed up a small area of the South Pacific Ocean, creating a massive tsunami travelling at 200 miles per hour across the ocean causing major damage to other countries and islands like Hawaii, Japan, the Philippines as well as the entire West Coast of the United States.

Who would have know that the worst earthquake in Mexico history would have have effected 32 years later? That this earthquake kill so many people and left so many homeless on the streets? Because that late afternoon there whole world turn upside with each step on the way there whole world collapse. This earthquake left people to struggle while the President Enrique Peña Nieto did nothing to help them out. The people were digging through the rock pile looking for kids or people. Not only did it affect the people in Mexico City but also Morelos, Puebla state, Guerrero state and Oaxaca. People are joining together to become this strong establishment for each other. While people were looking-for-hope they did one Frida-Sofia she build the hope
