Northern California Earthquakes Report

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.

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.

The San Francisco earthquake on April 18, 1906 was one of the most devastating earthquakes felt by a lot of states. At 5:15 am, this earthquake which registered at 8.25 on the Richter Scale shook San Francisco, California. The earthquake lasted less than a minute and it did a lot of destruction in that period of time. The most destructive part during the San Francisco earthquake was the fires which began after, as a result of the earthquake. The fires killed about 3,000 people and left 400,000 homeless (San Francisco Earthquake). The San Francisco earthquake epicenter was located near San Andreas fault and as a result, the damages caused by the earthquake was felt many miles along the San Andreas fault line. The city of San Francisco was known for its culture and economy, and because of the impact of the earthquake and fire, the city was in total disaster. Because of the magnitude of the earthquake and the amount of damage it did to the city of San Francisco, a lot of data and digital images have been collected so that it can be used for references and be displayed at its anniversary.

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.

Over more than 50 decades there has been multiple earthquakes that have been caused by the activity that takes place beneath and above the surface of the earth. For every earthquake there are various effects and consequences, these are generally not preventable but teachable moments. As we study and explore landforms we learn and better understand how today 's structures came about, what took place decades ago and where do we go from here. Thanks to the technology and inquiring minds we are able to study past events like the 1906 San Francisco earthquake and the 1964 Alaska earthquake. In comparing these two events we can get an overview of what happened and better prepare ourselves for something like that in the future.

The tectonic setting for the 1906 San Francisco Earthquake was in the outermost shell of earth consisting of rigid plates that have been moving for hundreds of millions of years. Two of these moving plates meet in western California; the boundary between them is a zone of faults, the principal one being the San Andreas fault. The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accommodating horizontal relative motions (usgs.gov).

A ‘hazard’ can be defined as a geophysical process operating within the lithosphere, atmosphere, hydrosphere or biosphere which could potentially lead to the loss of human life or property. However, an earthquake only becomes hazardous and therefore needs management if it occurs within close proximity to a vulnerable population. To some extent, any human settlement around the world situated close to or on top of an area of seismic activity is vulnerable. However, not all nations suffer equal devastation.

With more than 2,000 faults throughout California, an earthquake can happen at any time throughout the year. The Uniform California Earthquake Rupture Forecast estimates that within the next 30 years, the likelihood of a 6.7M or greater earthquake in California is 99.7%. Will you be prepared when it happens? Will you be able to rebuild your home?

The Northridge earthquake in 1994 caused widespread damage to not only the northern ridge area of Los Angeles but created major transportation issues for surrounding communities.

Oklahoma has been on the spotlight for the last few years owing to the increase in earthquakes. Particularly, 2014 served a wake-up call for stakeholders such as government, researchers and oil and gas industry members as a result of a sharp rise in earthquakes reported in the area. The year saw Oklahoma receiving more earthquakes than compared to California, a region that is more culpable to the earthquakes scene. In adition, 2014 also marked the largest earthquake reported in the history of the region, reporting a massive 5.6 magnitude. With these developments, continous research has been conducted and the review of peer and academic journals written by past reseaerchers and academic institutions collected to add on the data required to unearth the cause of the frequency of registered earthquakes as well as the underlying factors that contribute to seismic activity.

The main topic of this article is the possibility of larger earthquakes on the San Andreas Fault. These earthquakes would stem from small scale earthquakes in the Salton Sea near southern California. There is reason to believe that the Salton Sea area could be having more of an impact on how the San Andreas Fault reacts over time.

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.

Earthquakes are one of many natural disasters that occurs around the world. This natural disaster causes both destruction of the Earth’s surface and its lithosphere. The cause of these violent natural disasters is when two tectonic plates, slide past each other at a transform plate boundary. Before the plates slide past each other, they get stuck and cannot move. Stress forms and when it becomes too great, a rapid release of energy causes the earthquakes to happen, which produces seismic waves. Seismic waves cause vibrations which can cause faults to form or a crack in the Earth’s lithosphere. Earthquakes have an impact on buildings by the waves causing vibrations that can be so violent, they can crumble a building.

An earthquake is the shaking of the earth’s surface, resulting from the sudden release of energy, which creates seismic waves within the earth’s lithosphere. One of the most dangerous and most destructive natural occurrences on Earth is known as earthquakes. Earthquakes are sudden violent shakings of the Earth’s ground. Earthquakes are sudden vibrations in the surface of the Earth caused by the force and pulling of rocks between faults. Each earthquake is different and can range in size from weak ones, which cannot be felt, to violent enough to destroy whole cities and people. The seismic activity of an earthquake refers to the frequency type and size of the area in which an earthquake can occur, experienced over a period.
