The New Madrid Fault

The San Andreas fault line has caused constant development nightmares for large urban areas such as San Francisco as well as the other cities built on top of it. Fault lines are one of the side effects of the earth’s tectonic plates shifting that can result in devastating earthquakes. Some of the most devastating earthquakes in our modern era have occurred along the San Andreas fault line due to a dense population. The most notable and destructive earthquake on the San Andreas fault line occurred in San Francisco in 1906. The reason this earthquake was so deadly was because of its magnitude and the city’s poor planning. This earthquake was a wakeup call for San Francisco and force the city to revolutionize its knowledge on earthquakes and how to protect their city. Today San Francisco is one of the most well prepared cities for an earthquake and has made great discoveries in earthquake safety measures. The 1906 earthquake in San Francisco has drastically changed how the city has developed its zoning and building code policies, and its earthquake research.

About 4000 people were killed over 9000 that were injured that was this famous event you might ask? It was the loma prieta earthquake, also known as the world series earthquake. Taking place in san francisco 1898 this was one of the strongest earthquakes ever recorded in the bay area. This earthquake caused an estimate of 5.6 billion dollars for the total damage it had done .The person the was interviewed for this event was Mr.Demichel.he was about 10 when he felt the earthquake.

The three faults being considered are thought to have influenced the character of some 120,000 square miles. The Big Pine, Garlock, and San Andreas faults are all mutually active, deep, long, and steep and noted as being conjugate shears. In concert, the faults have defined a primary strain pattern of relative east-west extension and north-south shortening of the area of 120,000 square miles. The large region is noted for its deformity, with the source of this being a northeast-southwest counterclockwise compressive couple. The compressive couple was potentially supported through drag as a result of the deep-seated movement of rock material from the Pacific region (Hill & Dibblee, 1953). The interaction of the faults in the San Andreas region since the Jurassic period have served to shape and contour the present geology of the land, while a study of the paleontology of the region likewise requires such knowledge to effectively determine conditions at any given point in time.

The city has a mild year-round climate with an average of 201 days above 70 degrees. A sign of global warming is that the average surface temperature of the water has increased 3 degrees since 1950. San Diego lies on approximately 200 deep canyons and hills, creating small pockets of natural open space scattered throughout the city and giving it a mountainous geography. Due to this scattered open space, it causes a significant change in climate over short geographical distances. The San Diego River runs through the middle of San Diego while several reservoirs lie between and also separate the developed areas. The city also runs through two fault zones, the Rose Canyon and Point Loma faults, which are part of the San Andreas Fault system. It

Kathryn Schulz has provided insight of the dangers of the Cascadia Subduction Zone and the lack of our countries preparedness. Seismologist has detected and proven probability of an enormous earthquake and/or tsunami that is over due to take place along the western coast line and yet the lack of preparedness is evident. Thousands of lives will be lost due to unpreparedness.

California’s unique geography as a state makes it a very appealing place to call home. From the odd east to west transverse San Gabriel mountain ranges of the Los Angeles Basin, to the bumpy coastal ranges of the Bay Area, any person can find a compatible topographic terrain to their liking. California may seem to be the perfect place to live with its ideal climate and extensive geographic features. However, due to California’s location over the shifting continental plates, coupled with its enormous and also multiple faults, at any time this great state can fall victim to a seismic disaster. After examining evidence from both Rong-Gong Lin’s II Los Angeles Times article of April 18, 2016 and the NOVA videos Killer Quake ( 2006), Earthquake (2007), as well as Geologic Journey II – Episode 3 (The Pacific Rim: Americas) – Part 3 (San Francisco) and The Great San Francisco Earthquake (American Experience ~ 2005), one can take a comparative account of the three major earthquakes of California’s past. Although each earthquake was very devastating on is own; the Great Quake 0f 1906, the Loma Prieta quake of 1989, and the NorthRidge quake of 1994 each amounted to an extensive forfeiture of property and life. Each of these earthquakes created much suffering and loss. It is imperative for each citizen of this great state to understand the damage that a California quake can actually do and be prepared; for the threat of one always looms.

According to the research report, it will cause thousands of people die, towns submerged, buildings and bridges damaged once a huge earthquake and tsunamis happened on the Pacific Northwest area near American coast. And losses will be estimated at over 5 billion dollar US dollars. This shocking article was composed by seismic safety advisory committee in Oregon. According to materials, a super-strong earthquake once happened in A.D. 1700 Cascadia Subduction Zone (CSZ) on the Pacific Northwest coast. There are some experts forecast that another super-huge earthquake will occur in the future. The report has shown that once the earthquake occurs, the regions from North California to British Columbia Coastal region will suffer devastation, cause heavy casualties. Water and electricity shortage issues definitely follow this heavy disaster, meanwhile, communication and heating system and gas supply will definitely broken off in the light of this earthquake. The CSZ is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. It separates the Juan de Fuca (Juan

• This earthquake may not have released all of the strain stored in its rocks next to the fault this reveals a potential earthquake in the Santa Cruz Mountains in the near future. The occurrence of the earthquake showed that the Earth did not exhaust all its strain and hence other earthquakes could be expected. However, the dates could not be predicted. The extent of the damage could have been much more devastating for the region, but with the earthquake occurring near the coast this made half of the felt area westward in the Pacific Ocean. The occurrence of aftershocks ten days later reinforces the unpredictability nature and hence makes Geology to be a study that is always evolving. In conclusion, the Earth and the study of cannot be exhausted as every natural occurrence provides a new puzzle to be solved.

Type of event, training, or exercise: (actual event, table top, functional or full-scale exercise, pre-identified planned event, training, seminar, workshop, drill, game, etc.)

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

In recorded history, there have been 151 earthquakes in Nevada that were a magnitude of 3.5 or higher. As previously mentioned, the mountain ranges of Nevada are typically bound on one side or the other by a fault. There are quaternary faults that range in ages from less than 150 years to around 1.8 million years in existence. The property damage in Nevada from earthquakes was .2 million dollars between 1196 and 2014 based on information from department of energy for the state. As we studied in our textbook, earthquakes can by a number of things, such as shifting faults, or volcanic

Minimal impact to the inhabitants of Missouri was due to the sparse population at the time. Although a large earthquake is possible, scientists estimate the chances of a 7-8 magnitude earthquake occurring in the New Madrid Seismic Zone in a 50 year period is about ten percent. The Missouri Geological Survey (MGS) reminds people that prior preparation and knowledge are essential to getting through any natural disaster. The MGS also works with the U.S. Geological Survey to increase information about earthquakes occurring in the central United States (Earthquakes).

Have you noticed the amount of natural disasters that have occurred lately? Recently, natural disasters have been happening such as hurricane Harvey, Irma, and the 7.1 magnitude earthquake Mexico experienced. Sadly, California could be next to be hit from an earthquake.

The San Andreas Fault is one of the most widely studied faults in the world. Scientists use an array of methods in collecting data and providing analysis of fault characteristics both past and present. Presently there are many differing hypothesis and models used to describe crustal movements and deformation within the Pacific and North American plate boundary. Historical earthquakes along this fault have proven to be rather large and devastating. This is important since the San Andreas Fault runs along many highly populated areas throughout Northern and Southern California. Through further research and analysis of this fault system scientists hope to solve

State thesis&main points: So, in the speech, I am going to introduce how the earthquakes cause the damage to human; tell about the earthquakes prediction and why we need to have a rescue plan.
