Psychology and Geology

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 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

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.

• 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 San-Francisco earthquake caused quite a lot of damage in the area, but what is an earthquake? An earthquake is the movement of tectonic plates along a transform boundary and what plate is California sitting on? The Pacific Plate which is not connected to the North American plate and the plate boundary is a transform boundary. Earthquakes occur so often there that people say it is like a rainstorm that is ignored. The place where the Pacific Plate is grinding along with the North American Plate is called the San Andreas Fault. As stated before the earthquake had a magnitude of 7.8 which caused so much destruction a fire broke out. Nobody really knows where the fire started but it burned for 7 days and scorched over 500 city blocks leaving the once proud and powerful city into dust. The combination of the earthquake and fire is said to have killed “ Over 700 deaths by the earthquake and fire is now believed to be an understatement the total loss of life by a factor of 3 or 4.” (The Great 1906 San-Francisco Earthquake.)

The Loma Prieta earthquake was one of the most destructive earthquakes in California history. The Loma Prieta earthquake happened on Tuesday, October 17, 1989, at 5:04 pm. It was a 6.9 magnitude earthquake on the Richter Scale. It lasted approximately 15 seconds. The epicenter of this massive earthquake was located in the forest of the Nisene Marks State Park, near Loma Prieta peak in the Santa Cruz mountains. The epicenter is approximately 60 miles south of the big town of San Francisco. Loma Prieta was triggered by a slip along the famous San Andreas Fault. Also, the quake caused damage

The 9th of February 1971 an earthquake occurred in the lower parts of the San Gabriel Mountains in southern California. The San Fernando earthquake was measured to have a magnitude of around 6.5, which caused severe damage to buildings and major freeways in the Los Angeles area. Two huge health care buildings in San Fernando caused the majority of deaths when they collapsed at both sides. The epicenter of the earthquake was located in the mountains and the most severe damages occurred in northern San Fernando Valley. However, the event impacted other densely populated areas in Los Angeles and caused huge difficulty for transportation as a result of failure in several roadways and freeway interchanges.

Natural disasters are a huge challenge for the planet because of the adverse effects that are associated with them. One of the major earthquakes to have shaken the earth is the Great Sendai Earthquake or Great Tōhoku Earthquake that occurred in 2011. The event started when a powerful earthquake hit the northeastern Japan on March 11, 2011, and resulted in a widespread damage on land. A series of massive tsunamis later devastated many parts of the coastal regions of the country with the worst affected being the Tohoku region. The tsunami further resulted in a major nuclear accident that damaged distant regions on a power station located along the coast. The economic effects of the tsunami qualify it as one of the major natural disasters because it affected Japan’s economic stability as the country ended up resorting to importing as an alternative to cover the loss.

On Friday March 11th, 2011 at 2:46 pm, the fifth largest earthquake recorded since 1900 with a magnitude of 9.0, 1.7 Richter scale points greater than the devastating Vancouver Island earthquake of 1946, struck the coast of Japan, 231 miles northeast of Tokyo1, causing a devastating regional and global catastrophe.

The 1906 San Francisco earthquake struck the coast of Northern California at 5:12 a.m. on April 18 with an estimated moment magnitude of 7.8 and a maximum Mercalli intensity of XI . Severe shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in the city and lasted for several days. As a result, about 3,000 people died and over 80% of the city of San Francisco was destroyed. The events are remembered as one of the worst and deadliest natural disasters in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high in the lists of American urban disasters.

Living in Japan I knew we would experience earthquakes but I never thought I’d experience one so devastating to the whole country and nearby countries. March 11, 2011 was suppose to be a normal Friday, but at exactly 2:46pm, after I got home from school, everything changed. We were hit by a massive earthquake. I was terrified, so many thought were going through my head. I didn’t know if my friends and family were okay. I was leaning against the wall watching my cabinets open and cups fly out and picture frames fall and break. I could see the towers behind my house swaying back and forth as loud sirens went off all over the base. It was like this for 2 minutes. The longest and most terrifying 2 minutes of my life. Throughout the day there were many aftershocks. It felt like they were never going to end. Later that day a nuclear power plant exploded and the air was

The Loma Prieta earthquake occurred on October 17, 1989 at 5:04 p.m. It had a moment magnitude of 6.9, and lasted 15 to 20 seconds. The epicenter was near Loma Prieta, and this earthquake again caused severe damage to the San Francisco Bay Area, this time claiming 63 lives but almost 4,000 people were injured as a result of the earthquake.

In March of 2011, a magnitude 9 earthquake hit Japan, releasing a dangerous tsunami. Japan was not expecting the magnitude of the earthquake and tsunami, and endured much hardship after the disaster. The effects of the tsunami can still be seen in Japan today through its residents, economy, and through actions that have been taken to further protect residents from future disasters. Though the Japan 2011 tsunami is one of the most destructive tsunamis ever recorded, dangerous tsunamis continue to take place across the globe. The Japan 2011 tsunami not only affected the inhabitants of Japan, but also affected people around the world. After disasters such as this, each area must endure the aftermath of the disaster and recover from the effects.
