Salton Sea Earthquake

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.

According to Townend and Zoback (2004) the San Andreas Fault (SAF) region has been noted for its possession of stress orientations in addition to the lack of a distinct heat flow anomaly at the trace of the fault. These findings indicate that there are average shear tractions that are less than 20-25 MPa in the seismogenic upper crust. Oftentimes, shear tractions measure approximately 5 times greater than in the SAF. Due to the presence of high

Fault. As I researched, the reality of the potential effects to our state came into light. To be perfectly honest, I don’t think I had ever even heard of the New Madrid Fault. It could have been mentioned in my 7th grade Earth Science class, but that’s been a few years ago. As my internet investigation into the New Madrid Fault unfurled, the predictions of a massive earthquake happening in the region within the next 50 years was mentioned a number of times. So I thought I would begin my research into the history of the New Madrid Fault in regards to our state. Which lead me to think is our state prepared for an earthquake? What would the response be, not only from an emergency management point of view, but I will draw from my experience as a member of the Air National Guard.

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.

The earthquake was located on the San Andreas fault which is a seismic zone between two of the earth’s tectonic plates. Seismic events which occur is caused as a result of the earth’s tectonic plates moving against each other and this can cause huge earthquakes and volcanoes (“Young”). The transform boundary passes through California and this is where the Pacific and North American plates move past each other without colliding. The event in which this occurred was the San Andreas fault (“Young”). When the plates move past each other and the resistance builds up, this causes an earthquake like the 1906 San Francisco earthquake. This earthquake caused a separation and displacement in the landscape which was seen over several kilometers

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.)

d) The fault that is considered the most dangerous today in Southern California is San Jacinto. There are more people living on this fault, which means that if a deadly earthquake hits then it would affect a lot of people and there would be a lot of damage. The fault is 130 miles long.

I have read many books on seismology and am fascinated about the geology of our planet and the Gaia theory. (That our planet is alive and moving) I think the class will find the topic interesting because everyone lives in the Bay Area and will be directly affected by a major earthquake in the Bay Area. The three main points I will discuss are: 1) What are earthquake Faults? 2) Which Fault in the Bay Area is the most dangerous, and 3)

The state of California is home to notorious fault lines such as the infamous San Andreas fault. In Northern California, there are six significant Bay Area active faults: Calaveras, Concord-Green Valley, Greenville, Hayward, Rodgers Creek, and San Gregorio Fault [1]. After the Loma Prieta earthquake of 1989, propagating from the Santa Cruz Mountains, caused approximately $6 Billion dollars in damages [2]. Many infrastructure agencies altered their design and operations standards to prepare themselves for the next major earthquake. The Bay Area Rapid Transit system (BART) and The Pacific Gas and Electric Company (PG&E) have made changes so above and below ground infrastructures are prepared to withstand potential damages from seismic

California is due to be hit by an earthquake with an high magnitude of 8.0 comparable to the 1906 San Francisco 7.6 earthquake.

Earthquake Hazards occur when there are adverse effects on human activities. This can include surface faulting, ground shaking and liquefaction. In this essay I will be discussing the factors that affect earthquakes, whether human such as population density, urbanisation and earthquake mitigation or physical such as liquefaction, magnitude, landslides and proximity to the focus.

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
