New Madrid earthquake of 1811-1812 was known to be “one of the most powerful earthquake felt throughout the Eastern United State”(2,75) . “December 16, 1811 at 2 a.m”(1). , the first earthquake had struck in the Northern part of Arkansas through Missouri. “This earthquake occurred in Central Mississippi Valley”(2,2) . New Madrid fault is located in the northern part of Missouri and southern part of Illinois. On the morning of December 16, 1811, when the earthquake struck; “people were scared”(10,26) , they ran out of their houses as the trees were falling onto the ground and the ground was breaking up. After the earthquake ended, around 7 a.m., one of the largest aftershock occurred and it was known to be a destructive shock because
The Long Point Fault is located in Harris County, which covers 83,450 square miles located with in Houston, Teaxas City Limits. Research specifies that there are three sections of the Long Point fault that appear to be active; some sections of the Long Point fault have averaged more than 2 cm per year of vertical offset over the last 20 years. Evidence of the faults concludes it is a natural fault. The reason for activity is not caused by man, even though man’s activities are not helping the issues, but clearly humans are not the initial cause, biological activity can be in fact an adiitional cause for its movement. A brief description of the type of fault and its relationship with the strata and the faults beneath the Houston area, are at depths of 1,000 to 4,000 m. They have been well-defined through the study of well logs and seismic lines. Studies have resuted in assumuptions that some of these subsurface faults penetrate younger sediments at shallower depths, and contain faults that have of set the present land surface to produce recognizable scarps.

In 1910 a series of fifty-two earthquakes struck Arizona between September 10th-23rd and it caused much of the Flagstaff residents to flee the area as even strong households cracked and chimneys crumbled. The fifty-two earthquakes were all light-shock earthquakes with magnitudes between 4.0-4.2 that came right after another. If only one earthquake occurred in that timespan then it is likely that only objects would be knocked from shelves but no damage would be done to infrastructure, but the earthquakes happened right after another causing significant slight
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.
An earthquake felt throughout the Midwest on June 18 was a shaky reminder that earthquakes can occur anywhere.
Imagine if a 9.0 earthquake struck the West Coast today, resulting in a giant tsunami. Coastal towns would be washed away or completely isolated, and electricity would be lost (FOX5). There would be $70 billion in damage and people would only have 15 minutest to evacuate or move to higher ground resulting in 10,000 deaths (FOX5). This sounds like a plot for a scary movie, but this is actually a reality. The Oregon Coast in located on a subduction zone, which makes it very susceptible to major earthquakes and tsunamis. With the Cascadia subduction zone running along he West Coast the threat of a major tsunami is very real.
When the quake, registering 6.1 on the Richter scale, first struck, it was thought to be centered along the Old Whittier Fault. However, after extensive study, it was determined that it was actually the result of a "new" fault, or a fault that had not previously been discovered by scientists.
1906 San Francisco Earthquake Jared E. Gatchalian San Jose State University. 1906 San Francisco Earthquake The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damage and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco.
In the southern region of Los Diablos streets and freeways throughout the county suffered surface buckling and fractures due to widespread shaking from major super-quakes with partially severed bridges and freeway overpasses.
Heaven is a place on earth. In the hit Netflix original television series Black Mirror, specifically the episode “San Junipero,” individuals are allotted 5 hours a week to enter a virtual reality to live as a younger version of themselves. Individuals can then choose to ‘pass over’ or upload their consciousness into a cloud and become permanent residents of the town, San Junipero. The show centers around two women who become lovers connected by their want of nostalgia. Nostalgia defined by Svetlana Boym is a “longing for a home that no longer exists or has never existed… a sentiment of loss and displacement” (XIII). San Junipero, has allowed two broken people connected by nostalgia to live together forever in a utopia but in reality, San Junipero
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...

The Golden Gate Bridge is a major tourist attraction in San Francisco, California. It is one of the longest suspension bridges in the world and it’s also the top suicide location in the world.The Golden Gate Bridge is a symbol of Northern California. The bridge serves as a means of transportation.
The Tangshan earthquake was the second deadliest earthquake on record. It began in Tangshan, China at 3:42 on July 28, 1976 and took many lives. The citizens and their families were asleep when a 7.8 magnitude earthquake began to violently shake the ground beneath them. Earthquakes in China average at around 4.7 magnitude so, this one unordinary. The earthquake was caused when two underground plates moved past one another and eventually broke from all of the built up pressure. Citizens were unable to scramble to safety in time because the novice systems failed to detect the earthquake in time. Tangshan officials relied on surveying the land and how the storm altered the surrounding environment. Because of the power of this earthquake, it caused
Earthquakes occur around us all the time. Most are too small to notice and cause little to no damage. However, every so often large earthquakes do occur. Large earthquakes leave catastrophic damage a...
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).
