Los Angeles Earthquake Report

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.

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.

Recently, District of North Vancouver has released the results of a detailed five-year study that models a shallow 7.3 magnitude earthquake, with epicentre in the Strait of Georgia, risk in the municipality. Although this might not be the worst-case scenario,it still provides useful information in terms of determining the vulnerability of North Vancouver facing an earthquake. The bright side of the evaluation is that majority of people live in wood frame houses, which are inherently better able to withstand earthquake damage and most are built on stable, solid ground. That would be especially important if an earthquake struck at night, when most people are home.The dark side is that areas likely to be most impacted by ground shaking and soil failure in an earthquake, especially buildings in several low-lying waterfront areas would likely be topple as sandy soils were subject to liquefaction just like the below figure has shown where the red parts indicate areas near the shore or the waterfront is facing structural failure and danger of collapse. Looking to the upper regions, it is shown in this scenario that these areas would receive no significant structural damage when experienced a 7.3 magnitude earthquake. In general, North Vancouver is less dangerous under the condition

Last night a magnitude 7.0 earthquake struck the greater salt lake area causing severe damage to a number of vital areas in the valley. Experts have pointed to the I-80 and 1300 East as the epicenter of this quake. There is severe damage to buildings in this immediate area as many building here were built with un-reinforced brick. Many of the roads including the I-80 are inaccessible making travel in the area very difficult to navigate. Another tragedy in this event is the damage to the area around many of the hospitals in the north east part of the valley. While the hospitals themselves did not suffer as much damage the roads leading up to them did not fare as well. If we look further to the west at the airport, there is considerable damage

In order to survive during an earthquake, you must be very aware of how exactly to react and what to do in order to survive. The California Department of Public Health informs families to make a plan to evacuate their homes and find a safe place to go after the first sign of an earthquake (Earthquakes). This is the right thing to do, but people need to know where to go and how fast they need to act. Currently “California does not have an operational earthquake early warning system” (California Seismic Safety Commission) which could warn people when they need to evacuate before the earthquake even hits. I believe that the government of California needs to bring the early warning system back into their safety procedures. The government could also make clear where citizens from each county should go short term and long term in the case of an earthquake. Evacuation plans need to be made for when the earthquake is occurring when people need to find cover where nothing is going to fall on them. Plans for after the initial shaking need to be made as well, telling people to start heading inland toward surrounding states. This plan, however, requires the public to avoid driving over fault lines that could potentially move again. The San Andreas fault system is more than 800 miles long (Oskin), therefore people will need a set evacuation plan in order to know how to evacuate properly. The

One of the most significant earthquakes to hit the San Fernando Valley in the past was the 1971 San Fernando/ Sylmar earthquake. On February 9, 1971 at about 6 o’clock the cities of San Fernando and Sylmar experienced an earthquake that ruptured along the Sierra Madre Fault Zone (Oakeshott, Gordon B). The epicenter of this earthquake was reported to be in the San Gabriel Valley Mountains above the valley. The citizens of both cities felt tremendous shaking. The magnitude of the earthquake was measured as a 6.6 on the Richter scale and the shaking had the intensity of a level 11 (extreme) on the Modified Mercalli system (U.S. Geological Survey). The shaking of this 6.6 magnitude earthquake lasted about 12 seconds with a very strong ground motion. The source of this faulting was located about five miles to the north of the San Fernando valley. The surface faulting of this earthquake was reported to be seen along the surface of the San Fernando fault zone from a point south of Sylmar, the faulting stretched 6 miles more as far as east to the little Tujunga Canyon, also more surface faulting was reported more east as well. In total the maximum surface rupture was 12 miles and the amount of slip was about 6 feet (U.S. Geological Survey). The type of fault scientist label this earthquake to be was an oblique-slip or also known as a thrust. The depth of this earthquake was 13km (8.1 mi) and the peak acceleration was when it reached the Pacoima dam having the speed of 1.25g (U.S.

Earthquakes are environmental catastrophes which are unpreventable by human beings. While major earthquakes are not predictable, they could be further understood through scientific analysis of infrastructure evidence made by seismologists. The Hayward Fault in northern California poses a great seismic hazard for a megathrust earthquake. This paper utilizes environmental evidence along the fault line to further understand the nature of this major fault and the probability of a major earthquake occurrence.

On April 18, 1906 a magnitude 7.8 earthquake struck the city of San Francisco, California at 5:18 in the morning. Major fires followed the quake, and burned down the city for several days, as the firefighters had no water source to kill the fires. How did this earthquake happen? The answer: The 1906 earthquake occurred because of movement along the San Andreas Fault. Earthquakes are constantly happening in different places and because of various reasons. Scientists are constantly working to understand earthquakes and the reasons for their occurrences. Although some people think earthquakes have simple causes, they may be interested to know that earthquakes are caused by movement along faults, hydraulic fracking, and volcanic eruptions.

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.

More than 25,000 residents are now displaced. People are forced to move out of their homes to find better living conditions. Former residents do not want to deal with major highways blocked off by collapsed buildings and the loss of their precious Cathedral. As a result of both earthquakes, the town is crumbled and needs serious help. Those affected are fleeing the region without a place to go. Local shelters are now filled with about 15,000 residents. Some are calling the earthquake “apocalyptic” because of the massive life altering

Most of Mexico City’s habitants have experienced the phenomenon since they were kids. Somehow they are used to it, and they feel prepared in case of a seismic alert. But some of them, like me, are not. I was new in the city, when around 5 AM, the seismic

Murakami Haruki had a method with his stories, that captivated his audiences through the complexities of his plots as well as the obscure meanings within them. One of his stories, in the set of after the quake takes place in February 1995, after the disastrous Kobe earthquake. In this story, “Super-frog saves Tokyo”, Murakami chronicles the reactions of a disaster such as the Kobe earthquake through the narrative of a frog trying to save Japan from a worm that will cause an even more disastrous earthquake. Through this narrative, the portrayal of the animal protagonist, can be interpreted as a portend for both disaster as well as transformation. Through the use of Katagiri’s encounter with the frog, Murakami shows the instability of life and

It is awesome that you are an Emergency Manager in California. I am a former NASAR SARTECH II, K-9 Handler. When I lived in California one of the myths I was always scared of is, “when would the San Andreas cut off part of California as it slides into the ocean.” Being from the east coast, this scared me on every rumble. However, I learned the scare is in the disasters of structures and not in the Earth opening up a mouth to swallow me whole. San Bernardino is probably one of the best places to see the plate boundary in the city. It seems like every time the plates move, the roads traveling along the fault are destroyed. It is hard for many people to understand a transform fault like San Andreas. The best analogy I have heard is, “imagine sliding

Purpose: Everyone will think that we are living in a peaceful state now and ignore to pay attention to the natural disaster information. On the contrary, this thought in your mind will reduce your sense of crisis. Believe or not, increase a sense of crisis of the earthquake and learn more earthquake information can decrease the damage when the earthquakes occur in our life

An earthquake is the vibration of the Earth produced by the rapid release of energy. Most earthquakes occur at a plate boundary, usually along the Circum-Pacific belt. They tend to be caused by the slippage along large fracture in the Earth’s crust, such as a fault for example. However, they can also occur from a volcanic eruption, or an atomic explosion. There are two different types of shocks to a major earthquake; there is a foreshock and an aftershock. The foreshock concedes of smaller earthquakes that precede a major one by some time period, and an aftershock that concedes of small earthquakes due to the adjustment of the crust after the major earthquake. Earthquakes affect numerous things, from soil liquefaction to construction, and the rupture of power, gas, and water lines. There are two ways to measuring the size of an earthquake, those are intensity and magnitude. The intensity is a measure of the degree of an earthquake shaking at a given locale based on the amount of damage, measured through the Modified Mercalli Intensity Scale which bases of the surveys of those whom were affected, and ranges from 1 to a 12. The magnitude is the total amount of energy released at the source of an earthquake, which tends to be measured on the Richter magnitude scale. This method is based on the amplitude of the largest seismic wave, and ranges from a -2 to infinity. Unfortunately there
