Los Angeles is one of the largest cities in the United States and one with the highest risk of earthquakes. Los Angeles is an urban environment that has high infrastructure which increases hazards associated with earthquakes. There are many factors that lead to the current knowledge of past, current, and future earthquakes occurrences. We are better able to understand where and why earthquakes are likely to occur and to be proactive to their hazards. Los Angeles is located approximately 60 miles from the largest and most active fault line in the United States. The San Andreas Fault line is the boundary between the Pacific Plate and the North American Plate. These tectonic plates slide past each other breaking rock, creating shaking and seismic waves in every direction. This shaking is what we know as earthquakes and the seismic waves are how they are rated based on severity. The L.A. area is located where slip rate of the plates is well known. The slip rates of the San Andreas Fault is calculated by its size and the rate that one plate moves compared to the other. The soft soil and near surface materials have low wave velocity which create more shaking as compared to hard rock. Observing the shear wave velocity can assist in estimating potential seismic activity. Energy released from slipping rocks on the fault line can travel many miles. The location at which this slip occurs is known as the focus and epicenter is directly above the focus on the earth’s surface. Earthquakes can create aftershocks that can produce more earthquakes for several months. Earthquake shaking hazards can be calculated based on earthquake history, fault slip rates, and can be used to predict earthquake probabilities and hazard zones. L.A.’s urban environment creates higher hazard zones and can cause more damage per capita. There are three main hazards zones that have been created for…...

Tennessee Hazard Assessment

...Hazard Assessment for Memphis, Tennessee Environmental Geology April 24, 2012 Hazard Assessment for Memphis, Tennessee A natural disaster is defined as any event or force of nature that has catastrophic consequences (“natural disaster”). The only reason that these events are considered to have catastrophic consequences is because people are negatively affected by these natural events. If people were not present during these events, they would not be considered catastrophic. The more people affected means the event would be considered more catastrophic. Tennessee is the 17th most populated state, with approximately 6.4 million residents (Infoplease.com). Within the state, Shelby county covers the most area, (755 square miles), and is also the most populated county, with approximately 927,644 people residing there (Infoplease.com). Shelby county includes the city of Memphis. Memphis is the most populated city within Tennessee with at least 645,000 residents (Infoplease.com). I have attached several maps in order to see different parts of the land. Map I shows where the county lines are located within Tennessee. You can also see where Memphis is located within the county. Map II shows the elevation levels of the state. As you can see in that map, Memphis is located within the lowest elevation levels of the state. Map III shows the rivers that run throughout the state. The main river that runs between the Tennessee, Arkansas, and Missouri borders is the Mississippi River.......

Earthquake Hazard

...The city I chose for my hazard analysis is Los Angeles CA and the hazard that is the highest risk to the city is an earthquake. L.A. is the second largest city in the United States; it encompasses over 498 square miles and is surrounded by mountains and ocean. L.A. is a very urban environment, its high concentration of infrastructure makes it vulnerable to earthquakes, but at the same time it also gives it the resources it needs to respond to earthquakes or any other hazards. L.A. has had a few large scale earthquakes in the last decades and some geological experts predict it will suffer a major quake in the near future. How it has responded to those disasters in the past is what has laid the foundation as to how the city will deal with future earthquakes or other hazards and attempt to minimize their impact on the city. Los Angeles lies around 60 miles from the San Andreas Fault. This fault line is one the most active fault lines in the world and as such is capable of producing severe earthquakes. And even though Los Angeles doesn’t lie directly underneath it like the city of San Francisco, the fault line does pose a great danger to the city. But even more of a threat to the city is the many unknown smaller fault lines that run beneath it. With a population of over 4 million people, a large size earth quake would cause substantial damage and injure or kill a large number of people. L.A. has had around six major earthquakes that were 6.0 or stronger in the last hundred......

...The Philadelphia Water Department, Baxter Water Treatment Plant Anthony Vega, Denise Youmans, Christopher Williams, Stephen Glenn, Darnell Jessie Immaculata University EPM 301 Report Summary The purpose of this assessment is designed to look at the hazard vulnerability and exploitation potential surrounding The Philadelphia Water Department, Baxter Water Treatment Plant located at 9001 State Road in Philadelphia, Pa. The treatment plant must be prepared for every emergency when considering the safety of the community. This assessment is a detailed analysis of the possible catastrophic events that could occur in or near the water treatment plant and an inquisition into the possible contingency plans in the event that a catastrophe occurs. This assessment is designed to identify and assess hazards to which the Baxter Treatment Plant is ill-prepared to respond and strengthen these weak areas. Methods We, as a group, conducted site visits and surveys of the property. A point of contact was established within the Philadelphia Water Department, but the Water Department policies dictate that written approval for a site visit must be approved by higher level management. These policies and the limited amount of time in the accelerated semester did not allow us to complete an internal site visit. As a contingency, we evaluated the site from the exterior. Physical surveillance was conducted allowing us to observe the visible security of the premises. The building is......

...JP MORGAN & CHASE CO. TURNS BLIND EYE TO PONZI SCHEME: MORAL HAZARD PROBLEM Banks have been at the forefront of the financial system for as long as they have existed and have captured the attention of stakeholders on both controversial grounds as well as being undisputed with regards to the many helpful services they provide. JP Morgan & Chase is one such bank, surrounded by hostile news articles and excessive scrutiny but rightfully so as it has of recent been the topic of much controversy as turning a blind eye to the moral codes established by the Securities and Exchange Commission (SEC) and assisting Ponzi Scheme masterminds in swindling unsuspecting investors. On January 7th, 2014, JP Morgan was accused of assisting its high profile client of two decades, Bernard Madoff, a mastermind ponzi schemer in executing his goal of duping investors into parting with their savings worth a whopping $17.3billion of which included pension funds that belonged to JPM shareholders. The bank was fined a penalty of close to $2billion stemming from two felony violations of the Bank Secrecy Act, which is a federal law that requires banks to alert authorities to suspicious activity. The bank was further required to pay $543million in resolving private claims over losses tied to the scheme. A reported $9.5billion has been recovered whilst almost $4.9billion has been returned to investors. It can be agreed that this by far does not compensate for the losses the investors incurred.......

Hazards & Vulnerability

...Hazard & Vulnerability of Dhaka City 5 page ■ Dhaka City Population Area Urbanization River ■ Recent few incidents case study ■ Historical Hazard ■ Analysis and severity of hazards & vulnerability Bangladesh is a unitary, independent and sovereign Republic known as the People’s Republic of Bangladesh. Bangladesh emerged as an independent country on March 26, 1971. The war of liberation ended on 16 December 1971 with the victory of Bangladesh forces and the surrender of the occupying Pakistani Army in Dhaka, the capital of Bangladesh. From its beginning as a small city with a few thousand people, Dhaka actually experienced dramatic turns upward and today it has become one of the fastest growing mega cities of the world. Its existence as a major urban agglomeration has been consistent over a period of 400 years. Even the most developed cities in the world today cannot boast 400 years of uninterrupted and organised existence that Dhaka does as a historic city. In the 16th century during the reign of Mughal Emperor Akbar it was a thana or military outpost having a population of only 3000 people with an area of 2 km² (UNEP, 2005). Then turning Dhaka into a capital city of the eastern province in 1608 by Subedar Islam Khan was epoch making. Since then Dhaka has experienced actual urbanisation and trends of development. Area Dhaka is located in central Bangladesh at 23°42′0″N 90°22′30″E, on the eastern banks of the Buriganga River. The...

Hazards

...MGT2396 - Occupational Health & Safety Assignment #4 - Find the Hazards Hazard #1 Describe the Hazard: There are various electrical wires hanging from the ceiling, one being an electrical outlet. These hanging wires are near various metal and wood beams, we can assume that these wires are live carrying an electrical current. What type of Hazard: Electrical safety. Possible outcome if left unaddressed: If the employees whom work for this company need to use the electrical outlets, they would need to use the ladder to access them as they are hanging from the ceiling. This causes danger as the metal latter and the employee would be perfect conductors for the electricity. The voltage of the electricity and the available electrical current has enough power to cause death by electrocution (Hazards). All electrical systems have the potential to cause harm. Electricity can be either static or dynamic. Dynamic electricity is the uniform motion of electrons through a conductor Conductors are materials that allow the movement of electricity, most metals and the human body are conductors (Warehouse Hazards). If this is hazard is unaddressed it could result in injury, fire and even death. When electrical current travels through our bodies, it can interfere with the normal electrical signals between the brain and our muscles. Hazard #2 Describe the Hazard: Wooden planks are being stored in the ceiling rafters, these wood planks are being held up by other wood......

Hazards

...“Discuss the view that the impact of earthquake hazards depends primarily on human factors (40)”.  I agree to some extent about the statement above and that human factors can affect the impact of an earthquake hazard. A hazard is an object or process that has the potential to cause harm. Ground shaking, ground displacement and flooding are some of the hazards that are produced during an earthquake. In relation to the question above the type and severity of the impact can be affected by physical factors (such as the magnitude and frequency of the quake) as well as human factors (population density and education). I will be discussing the question using the following case studies, Sichuan, Indonesia and L’Aquila. On the 12th May 2008 an earthquake occurred at 2:28pm in Sichuan because the pressure resulting from the Indian plate colliding with the Eurasian was sent along the Longmenshan fault line that runs through Sichuan. The earthquake lasted 120 seconds and reached 7.9 on the Richter scale, one of the deadliest to strike China in recent years and its effects were felt as far away as Taiwan, Thailand and Bangladesh. Although the area has a long history of tectonic activity, it seems it was not prepared for an event of this magnitude. With a population consisting of 87.26m people the death toll stood at nearly 70 thousand along with 374,000 people injured and 5m left homeless. Making this Chinas worst earthquake since 1976 when 240,000 people were killed in Tangshan.......

Moral Hazard

...Introduction Moral hazard arises when an entity protected from risk may behave differently than they would bear all the consequences of risk. Moral hazard increases because individual people and institutions do not assume the consequences of their actions and, therefore, tend to behave less careful than would be the case bear the full consequences. An example is the behavior of the driver of the car, which in the absence of insurance is driving more carefully and ensure that the car is parked in a safe place and, above all, remember to lock the car. A special case of moral hazard is the principal-agent issue, which concerns the relationship between the party ordering the actions (the principal) and the party that is actively executing an agreement (the agent). To perform the contract, the principal entrusts control of your property agent but does not control his behavior fully. This raises the asymmetry of information and the possibility of conflict if the agent will act in their interests, using the resources of principal. The most common example is an employer-employee relationship or owner-management company. In some corporations dispersed owners or shareholders are not able to effectively monitor management actions because managers face the temptation to strive for rapid improvements in business performance and payment of wages at the expense of their development in future years Olympus Case Olympus story begins with the common problems we face the Japanese managers...

Future Hazards

...positive affect on crisis planning and response in the decades to come. The positive affects stems from the mass-media’s ability to quickly produce and distribute information leading to increased awareness of the risks and hazard perceptions. This should sequentially require Governments to act and take a more proactive stance against technological disasters and prepare for future crisis in a more organised manner. The article concludes by pointing out that disaster planning cannot be evaluated just in terms of reducing traditional kinds of loss. Account must be made of future hazards. Planning and response measures need to be realistic and recognise the limits to what can be achieved and projected. Nevertheless, the author believes that what has been projected is a realistic picture of what one might expect to happen in the 21st century. 3.0 MAJOR COMMENTS One of the main key learning points of this article is to highlight societies increasing vulnerability from both natural and technological hazards, especially with respect to increasing urbanisation and its concentration of people in hazardous areas. Cities are more complex to organise and creates a reliance on specialist technology leaving societies vulnerability to more and worse hazards in the future. There is also the beginning of recognition of the fact that natural disasters will generate or magnify concurrent technological disasters. Figures released by the World Health Organisation (WHO) in 1999,......
