Introduction
“The Pressure and Release Model understands a disaster as the intersection between socio-economic pressure and physical exposure. Risk is explicitly defined as a function of the perturbation, stressor or stress and the vulnerability of the exposed unit” (Coll, 2017). The disaster I have chosen to apply the Pressure and Release model to is Hurricane Harvey, Texas. I will discuss this disaster in relation to the pressure and release model which includes vulnerability and physical exposure. Inequalities and root causes lead to unequal social conditions, this makes a certain area more vulnerable to natural hazards (Tapsell et al., 2017). It also affects the impact the hazard has on many people and their ability to prepare for the hazard.

Root causes are described as “interrelated set of widespread and general processes within a society and world economy” (Coll, 2017). The root cause that is made clear here is the dysfunction of the local government and economy (Gabbatt, 2017). Root causes reflect the poorly distribution of power within the Texan society. Another factor that impacted the vulnerability of Houston is the fact that they are governed by nine separate local county governments which failed to communicate to construct an efficient plan for when a natural disaster would happen (Gabbatt, 2017). The economic system in Houston played another major role in the process of vulnerability. The low tax business strategy approach of Houston lead to the rapid urbanisation of the area (Gabbatt, 2017). Most of their tax income came from property tax. This was a big incentive for the economy, which meant development was allowed to happen where development wanted to happen (Gabbatt, 2017). The political structures were not thinking of the growing impact of these developments had on Texas when they were happening (Gabbatt, …show more content…
“To understand ways in which dynamic pressures channel root causes to unsafe conditions requires researching how dynamic pressures play out on the ground” (Coll, 2017). The most evident unsafe condition in relation to Hurricane Harvey is the lack of disaster preparedness and dangerous location. Considering lack of disaster preparedness Houston Texas failed to keep their drainage systems up to date as the city urbanised (Gabbatt, 2017). Regarding dangerous location, much of the city of Houston Texas is built on low lying land in the Gulf Coastal Plain (Gabbatt, 2017). As Houston Texas urbanised, space to build houses became limited and some began to develop inside and close to the boundary of Texas’ biggest reservoirs (Kimmelman, 2017). Concerning poor infrastructure, the immense increase in housing and footpaths meant hundreds of miles of concrete with badly planned drainage systems (Gabbatt, 2017). In relation to poor infrastructure, drainage systems are in place but often entail directing the excess water into places that have already reached their capacity (Gabbatt, 2017). The impermeable roads and paths built on the coastal prairie and the wetlands of the gulf almost guarantee flooding to occur (Gabbatt, 2017). This left Houston Texas vulnerable in terms of social protection. Regarding distinctive topography, Texas has a very low lying coastal plain
New Orleans, Louisiana lies at the second lowest elevation among major cities in the United States. It is a city surrounded by water, making it almost like an island. To counter this dangerous combination of the low elevation along with the lakes, rivers and swamps surrounding it, the Army Corps of Engineers built a series of levees around the city to foster its protection. It is these very same levees however that might doom the city should a Category 3 hurricane ever hit. Our statistical analyses examined the current belief that there is a 39% probability that New Orleans will be hit by a major hurricane and based on the resulting Z-score, rejected that belief. We did find however that the probability, while not 39%, was still in the 30th percentile range, which should still be a major cause for concern among the leaders and residences of the city of New Orleans.
Rather than working with nature through multi-tiered flood control with spillways and reservoirs, levees disallowed the river to naturally flood, deteriorated the natural ecosystem, and ultimately weakened the city’s defenses against the hurricane (Kelman). Culture and society further interacted, as beliefs in man’s power over nature and racial discrimination promoted levee expansion and racial segregation, creating a city of racially differentiated risk (Spreyer 4). As a result, inundation mostly impacted the lower land neighborhoods that housed poor people of color. Society and nature interfaced in the application of levees that contained nature’s forces. Ultimately, nature won out: the hurricane overpowered the levees and breached the Industrial Canal, disproportionally flooding the mostly black, low-elevation neighborhoods of New Orleans (Campanella
The oil boom is a driving force for urbanization, because it leads to population growth in cities like Houston, Dallas-Fort Worth, San Antonio, and Austin. Houston, the largest city in Texas, is one of the world leaders in the petrochemical industry, and its port provides access to the world market. Dallas is the commercial center of the city of Texas, with an emphasis on banking and real estate development. San Antonio of the economy focused on national bases, educational institutions, tourism and medical research. Together, these cities became political position and can help us understand the political economy of the state as a
In the late summer of 2005, a terrible tragedy occurred that changed the lives of many in the south-east region of the United States. A Category 3, named storm, named Hurricane Katrina, hit the Gulf Coast on the 29th of August and led to the death of 1,836 and millions of dollars’ worth of damage (Waple 2005). The majority of the damage occurred in New Orleans, Louisiana. Waple writes in her article that winds “gusted over 100 mph in New Orleans, just west of the eye” (Waple 2005). Not only was the majority of the damage due to the direct catastrophes of the storm but also city’s levees could no longer hold thus breaking and releasing great masses of water. Approximately, 80% of the city was submerged at sea level. Despite the vast amount of damage and danger all throughout the city, officials claimed that there was work being done to restore the city of New Orleans as a whole but many parts, and even the people, of the city were overlooked while areas of the city with higher economic value, and more tourist traffic, were prioritized along with those individuals.
Hurricane Harvey is located in Houston, Texas. It was the first major hurricane to make landfall in the United States since Wilma in 2005, ending a record 12- years period with no major hurricanes making landfall in the country. The sprawling and soaked Houston metro area and other deluge towns in southeast Texas braced for devastating floods and pummeling rainfall on Sunday as tropical storm Harvey stalled over land and drenched dogged searchers and anxious residents. Houston, Texas has set up shelters for people to stay out of the weather with good food, clean and fresh water, and dry, clean clothes. It is getting bigger and it has been confirmed that there will be more flooding close by to that area.

They found that various socio-demographic predictors of flood risk impact the difference across flood zone categories. The main residents in inland flood zones are non-Hispanic Black and Hispanic, while coastal flood zones have more higher median income and housing value residents. I considered the study a valuable reference for future flood hazard research and comprehensive public policy making. Social groups with higher vulnerability also tends to stay instead of moving away, for they do not have the affordability for moving to other neighborhood, giving up what they have and almost start from scratch. Thus, they are actually the group of people that suffers the most and paying the most towards natural events. It is also important for the government to create a official help system to improve their resilience.
Most of the destructions from the events of August 29th 2005, when Katrina Hit the City Of New Orleans, were not only caused by the storm itself; but also, by failure of the engineering of the levee system protecting the entire infrastructure of the city. The years of poor decision making and avoidance of the levee system led to one of the most catastrophic events in the history of the United States. Throughout our research, we have identified three key players in charge of the levee system design, construction and maintenance. These three organizations are the Unites States Corps of Engineers, the New Orleans Levee District and the Louisiana Department of Transportation. The consequences of the hurricane showed the organizations negligence in the design, construction and maintenance of the protective walls. Later independent sresearch showed that more than 50 levees and food walls failed during the passage of the hurricane. This failure caused the flooding of most of New Orleans and all of ST. Bernard Parish. The Unites States Corps of Engineers had been in charge of the of the levee system and flood walls construction since the 1936 flood act. According to the law, the Louisiana Department of Transportation is in charge to inspect the overall design and engineering practices implemented in the construction of the system. Once the levee systems were finished, they were handed over to the New Orleans Levee District for regular maintenance and periodically inspections. The uncoordinated actions of these three agencies resulted in the complete failure of a system that was supposed to protect the people of New Orleans. The evidence is clear that this catastrophic event did not happened by chance. The uncoordinated response of these...
By August 28, evacuations were underway across the region. That day, the National Weather Service predicted that after the storm hit, “most of the [Gulf Coast] area will be uninhabitable for weeks…perhaps longer.” New Orleans was at particular risk. Though about half the city actually lies above sea level, its average elevation is about six feet below sea level–and it is completely surrounded by water. Over the course of the 20th century, the Army Corps of Engineers had built a system of levees and seawalls to keep the city from flooding. The levees along the Mississippi River were strong and sturdy, but the ones built to hold back Lake Pontchartrain, Lake Borgne and the waterlogged swamps and marshes to the city’s east and west were much less reliable. Even before the storm, officials worried that those levees, jerry-built atop sandy, porous, erodible soil, might not withstand a massive storm surge. Neighborhoods that sat below sea level, many of which housed the city’s poorest and most vulnerable people, were at great risk of
Hurricane Harvey was one of the most devastating hurricanes to strike the United States in several years. Harvey resulted in over eighty fatalities and over 150 billion dollars in damages. This proves to be one of the most destructive hurricanes to be recorded. The overwhelming damage was caused by many different aspects; however, three of the greatest aspects are: varying weather patterns throughout the storm, the city structure of Houston, Texas, and the lack of evacuation. Each of these factors affected the city in a different way, but all resulted in a common outcome, devastation.
Imagine that a family is sitting at home watching a calm game of baseball, when suddenly they realize that a massive wall of water is approaching the neighborhood. Where did this flash flood come from, a reader might ask? The wall of water was made by the raging winds and immense power of Hurricane Andrew. Hurricane Andrew was the second most expensive storm in history that destroyed over 250,000 homes in the states of Florida and Louisiana alone. Hurricane Andrew was not predicted to make landfall, so when it did many civilians did not have any ideas that the Hurricane was coming until it was almost too late. Hurricane Andrew also caused many short and long term effects in the ecosystem and local economies.
Hurricane Katrina was one of the most devastating natural disasters to happen in the United States. The storm resulted in more then US$100 billion in damage when the cities flood protection broke and 80% of the city was flooded (1). The protection failure was not the only cause for the massive flooding, the hurricanes clockwise rotation pulled water from north of New Orleans into the city. 330,000 homes were destroyed and 400,000 people from New Orleans were displaced, along with 13,00 killed (1). Although the population quickly recovered, the rate of recovery slowed down as the years went on leading us to believe not everyone
On August 29, 2005 Hurricane Katrina made landfall on the Gulf Coast of the United States. The storm was measured as a category three hurricane which had reached winds of approximately one hundred and forty miles per hour. The storm had initially measured almost four hundred miles across affecting the areas of Alabama, Mississippi and Louisiana. Of these three affected areas, Louisiana contained the largest amount of damage; however, one city in particular suffered the greatest damage and was the primary focus of this disaster. That was the city of New Orleans. The city of New Orleans was at an incredibly high risk for a few reasons. One reason was that New Orleans was surrounded by significant bodies of water. Each of these bodies of water had contained levees that were built in the twentieth century, where some were stronger than others. Those levees that were not built properly held the greatest risk of being breached and causing treacherous flooding as well. Another factor included New Orleans being located below sea level, which had included the “city’s poorest and most vulnerable pe...
Hazards pose risk to everyone. Our acceptance of the risks associated with hazards dictates where and how we live. As humans, we accept a certain amount of risk when choosing to live our daily lives. From time to time, a hazard becomes an emergent situation. Tornadoes in the Midwest, hurricanes along the Gulf Coast or earthquakes in California are all hazards that residents in those regions accept and live with. This paper will examine one hazard that caused a disaster requiring a response from emergency management personnel. Specifically, the hazard more closely examined here is an earthquake. With the recent twenty year anniversary covered by many media outlets, the January 17, 1994, Northridge, California earthquake to date is the most expensive earthquake in American history.
